-# How to become a contributor and submit your own code
-
-## Contributor License Agreements
-
-We'd love to accept your patches! Before we can take them, we have to jump a
-couple of legal hurdles.
-
-Please fill out either the individual or corporate Contributor License Agreement
-(CLA).
-
-*   If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an
-    [individual CLA](https://developers.google.com/open-source/cla/individual).
-*   If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a
-    [corporate CLA](https://developers.google.com/open-source/cla/corporate).
-
-Follow either of the two links above to access the appropriate CLA and
-instructions for how to sign and return it. Once we receive it, we'll be able to
-accept your pull requests.
-
-## Are you a Googler?
-
-If you are a Googler, please make an attempt to submit an internal change rather
-than a GitHub Pull Request. If you are not able to submit an internal change a
-PR is acceptable as an alternative.
-
-## Contributing A Patch
-
-1.  Submit an issue describing your proposed change to the
-    [issue tracker](https://github.com/google/googletest).
-2.  Please don't mix more than one logical change per submittal, because it
-    makes the history hard to follow. If you want to make a change that doesn't
-    have a corresponding issue in the issue tracker, please create one.
-3.  Also, coordinate with team members that are listed on the issue in question.
-    This ensures that work isn't being duplicated and communicating your plan
-    early also generally leads to better patches.
-4.  If your proposed change is accepted, and you haven't already done so, sign a
-    Contributor License Agreement (see details above).
-5.  Fork the desired repo, develop and test your code changes.
-6.  Ensure that your code adheres to the existing style in the sample to which
-    you are contributing.
-7.  Ensure that your code has an appropriate set of unit tests which all pass.
-8.  Submit a pull request.
-
-## The Google Test and Google Mock Communities
-
-The Google Test community exists primarily through the
-[discussion group](http://groups.google.com/group/googletestframework) and the
-GitHub repository. Likewise, the Google Mock community exists primarily through
-their own [discussion group](http://groups.google.com/group/googlemock). You are
-definitely encouraged to contribute to the discussion and you can also help us
-to keep the effectiveness of the group high by following and promoting the
-guidelines listed here.
-
-### Please Be Friendly
-
-Showing courtesy and respect to others is a vital part of the Google culture,
-and we strongly encourage everyone participating in Google Test development to
-join us in accepting nothing less. Of course, being courteous is not the same as
-failing to constructively disagree with each other, but it does mean that we
-should be respectful of each other when enumerating the 42 technical reasons
-that a particular proposal may not be the best choice. There's never a reason to
-be antagonistic or dismissive toward anyone who is sincerely trying to
-contribute to a discussion.
-
-Sure, C++ testing is serious business and all that, but it's also a lot of fun.
-Let's keep it that way. Let's strive to be one of the friendliest communities in
-all of open source.
-
-As always, discuss Google Test in the official GoogleTest discussion group. You
-don't have to actually submit code in order to sign up. Your participation
-itself is a valuable contribution.
-
-## Style
-
-To keep the source consistent, readable, diffable and easy to merge, we use a
-fairly rigid coding style, as defined by the
-[google-styleguide](https://github.com/google/styleguide) project. All patches
-will be expected to conform to the style outlined
-[here](https://google.github.io/styleguide/cppguide.html). Use
-[.clang-format](https://github.com/google/googletest/blob/master/.clang-format)
-to check your formatting
-
-## Requirements for Contributors
-
-If you plan to contribute a patch, you need to build Google Test, Google Mock,
-and their own tests from a git checkout, which has further requirements:
-
-*   [Python](https://www.python.org/) v2.3 or newer (for running some of the
-    tests and re-generating certain source files from templates)
-*   [CMake](https://cmake.org/) v2.6.4 or newer
-
-## Developing Google Test and Google Mock
-
-This section discusses how to make your own changes to the Google Test project.
-
-### Testing Google Test and Google Mock Themselves
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test and GoogleMock's own
-tests. For that you can use CMake:
-
-    mkdir mybuild
-    cd mybuild
-    cmake -Dgtest_build_tests=ON -Dgmock_build_tests=ON ${GTEST_REPO_DIR}
-
-To choose between building only Google Test or Google Mock, you may modify your
-cmake command to be one of each
-
-    cmake -Dgtest_build_tests=ON ${GTEST_DIR} # sets up Google Test tests
-    cmake -Dgmock_build_tests=ON ${GMOCK_DIR} # sets up Google Mock tests
-
-Make sure you have Python installed, as some of Google Test's tests are written
-in Python. If the cmake command complains about not being able to find Python
-(`Could NOT find PythonInterp (missing: PYTHON_EXECUTABLE)`), try telling it
-explicitly where your Python executable can be found:
-
-    cmake -DPYTHON_EXECUTABLE=path/to/python ...
-
-Next, you can build Google Test and / or Google Mock and all desired tests. On
-\*nix, this is usually done by
-
-    make
-
-To run the tests, do
-
-    make test
-
-All tests should pass.
-
-### Regenerating Source Files
-
-Some of Google Test's source files are generated from templates (not in the C++
-sense) using a script. For example, the file
-include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-You don't need to worry about regenerating the source files unless you need to
-modify them. You would then modify the corresponding `.pump` files and run the
-'[pump.py](googletest/scripts/pump.py)' generator script. See the
-[Pump Manual](googletest/docs/pump_manual.md).

-## Welcome to **Google Test**, Google's C++ test framework!
-
-This repository is a merger of the formerly separate GoogleTest and GoogleMock
-projects. These were so closely related that it makes sense to maintain and
-release them together.
-
-Please subscribe to the mailing list at googletestframework@googlegroups.com for
-questions, discussions, and development.
-
-### Getting started:
-
-The information for **Google Test** is available in the
-[Google Test Primer](googletest/docs/primer.md) documentation.
-
-**Google Mock** is an extension to Google Test for writing and using C++ mock
-classes. See the separate [Google Mock documentation](googlemock/README.md).
-
-More detailed documentation for googletest is in its interior
-[googletest/README.md](googletest/README.md) file.
-
-## Features
-
-*   An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
-*   Test discovery.

-# Googletest Mocking (gMock) Framework
-
-### Overview
-
-Google's framework for writing and using C++ mock classes. It can help you
-derive better designs of your system and write better tests.
-
-It is inspired by:
-
-*   [jMock](http://www.jmock.org/),
-*   [EasyMock](http://www.easymock.org/), and
-*   [Hamcrest](http://code.google.com/p/hamcrest/),
-
-and designed with C++'s specifics in mind.
-
-gMock:
-
-   provides a declarative syntax for defining mocks,
-   can define partial (hybrid) mocks, which are a cross of real and mock
-    objects,
-   handles functions of arbitrary types and overloaded functions,
-   comes with a rich set of matchers for validating function arguments,
-   uses an intuitive syntax for controlling the behavior of a mock,
-   does automatic verification of expectations (no record-and-replay needed),
-   allows arbitrary (partial) ordering constraints on function calls to be
-    expressed,
-   lets a user extend it by defining new matchers and actions.
-   does not use exceptions, and
-   is easy to learn and use.
-
-Details and examples can be found here:
-
-*   [gMock for Dummies](docs/for_dummies.md)
-*   [Legacy gMock FAQ](docs/gmock_faq.md)
-*   [gMock Cookbook](docs/cook_book.md)
-*   [gMock Cheat Sheet](docs/cheat_sheet.md)
-
-Please note that code under scripts/generator/ is from the [cppclean
-project](http://code.google.com/p/cppclean/) and under the Apache
-License, which is different from Google Mock's license.
-
-Google Mock is a part of
-[Google Test C++ testing framework](http://github.com/google/googletest/) and a
-subject to the same requirements.

-
-### Defining a Mock Class
-
-#### Mocking a Normal Class {#MockClass}
-
-Given
-
-```cpp
-class Foo {
-  ...
-  virtual ~Foo();
-  virtual int GetSize() const = 0;
-  virtual string Describe(const char* name) = 0;
-  virtual string Describe(int type) = 0;
-  virtual bool Process(Bar elem, int count) = 0;
-};
-```
-
-(note that `~Foo()` **must** be virtual) we can define its mock as
-
-```cpp
-#include "gmock/gmock.h"
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(int, GetSize, (), (const, override));
-  MOCK_METHOD(string, Describe, (const char* name), (override));
-  MOCK_METHOD(string, Describe, (int type), (override));
-  MOCK_METHOD(bool, Process, (Bar elem, int count), (override));
-};
-```
-
-To create a "nice" mock, which ignores all uninteresting calls, a "naggy" mock,
-which warns on all uninteresting calls, or a "strict" mock, which treats them as
-failures:
-
-```cpp
-using ::testing::NiceMock;
-using ::testing::NaggyMock;
-using ::testing::StrictMock;
-
-NiceMock<MockFoo> nice_foo;      // The type is a subclass of MockFoo.
-NaggyMock<MockFoo> naggy_foo;    // The type is a subclass of MockFoo.
-StrictMock<MockFoo> strict_foo;  // The type is a subclass of MockFoo.
-```
-
-**Note:** A mock object is currently naggy by default. We may make it nice by
-default in the future.
-
-#### Mocking a Class Template {#MockTemplate}
-
-Class templates can be mocked just like any class.
-
-To mock
-
-```cpp
-template <typename Elem>
-class StackInterface {
-  ...
-  virtual ~StackInterface();
-  virtual int GetSize() const = 0;
-  virtual void Push(const Elem& x) = 0;
-};
-```
-
-(note that all member functions that are mocked, including `~StackInterface()`
-**must** be virtual).
-
-```cpp
-template <typename Elem>
-class MockStack : public StackInterface<Elem> {
-  ...
-  MOCK_METHOD(int, GetSize, (), (const, override));
-  MOCK_METHOD(void, Push, (const Elem& x), (override));
-};
-```
-
-#### Specifying Calling Conventions for Mock Functions
-
-If your mock function doesn't use the default calling convention, you can
-specify it by adding `Calltype(convention)` to `MOCK_METHOD`'s 4th parameter.
-For example,
-
-```cpp
-  MOCK_METHOD(bool, Foo, (int n), (Calltype(STDMETHODCALLTYPE)));
-  MOCK_METHOD(int, Bar, (double x, double y),
-              (const, Calltype(STDMETHODCALLTYPE)));
-```
-
-where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
-
-### Using Mocks in Tests {#UsingMocks}
-
-The typical work flow is:
-
-1.  Import the gMock names you need to use. All gMock symbols are in the
-    `testing` namespace unless they are macros or otherwise noted.
-2.  Create the mock objects.
-3.  Optionally, set the default actions of the mock objects.
-4.  Set your expectations on the mock objects (How will they be called? What
-    will they do?).
-5.  Exercise code that uses the mock objects; if necessary, check the result
-    using googletest assertions.
-6.  When a mock object is destructed, gMock automatically verifies that all
-    expectations on it have been satisfied.
-
-Here's an example:
-
-```cpp
-using ::testing::Return;                          // #1
-
-TEST(BarTest, DoesThis) {
-  MockFoo foo;                                    // #2

-### Setting Default Actions {#OnCall}
-
-gMock has a **built-in default action** for any function that returns `void`,
-`bool`, a numeric value, or a pointer. In C++11, it will additionally returns
-the default-constructed value, if one exists for the given type.
-
-To customize the default action for functions with return type *`T`*:
-
-```cpp
-using ::testing::DefaultValue;
-
-// Sets the default value to be returned. T must be CopyConstructible.
-DefaultValue<T>::Set(value);
-// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
-//  T MakeT();
-DefaultValue<T>::SetFactory(&MakeT);
-// ... use the mocks ...
-// Resets the default value.
-DefaultValue<T>::Clear();
-```
-
-Example usage:
-
-```cpp
-  // Sets the default action for return type std::unique_ptr<Buzz> to
-  // creating a new Buzz every time.
-  DefaultValue<std::unique_ptr<Buzz>>::SetFactory(
-      [] { return MakeUnique<Buzz>(AccessLevel::kInternal); });
-
-  // When this fires, the default action of MakeBuzz() will run, which
-  // will return a new Buzz object.
-  EXPECT_CALL(mock_buzzer_, MakeBuzz("hello")).Times(AnyNumber());
-
-  auto buzz1 = mock_buzzer_.MakeBuzz("hello");
-  auto buzz2 = mock_buzzer_.MakeBuzz("hello");
-  EXPECT_NE(nullptr, buzz1);
-  EXPECT_NE(nullptr, buzz2);
-  EXPECT_NE(buzz1, buzz2);
-
-  // Resets the default action for return type std::unique_ptr<Buzz>,
-  // to avoid interfere with other tests.
-  DefaultValue<std::unique_ptr<Buzz>>::Clear();
-```
-
-To customize the default action for a particular method of a specific mock
-object, use `ON_CALL()`. `ON_CALL()` has a similar syntax to `EXPECT_CALL()`,
-but it is used for setting default behaviors (when you do not require that the
-mock method is called). See [here](cook_book.md#UseOnCall) for a more detailed
-discussion.
-
-```cpp
-ON_CALL(mock-object, method(matchers))
-    .With(multi-argument-matcher)   ?
-    .WillByDefault(action);
-```
-
-### Setting Expectations {#ExpectCall}
-
-`EXPECT_CALL()` sets **expectations** on a mock method (How will it be called?
-What will it do?):
-
-```cpp
-EXPECT_CALL(mock-object, method (matchers)?)
-     .With(multi-argument-matcher)  ?
-     .Times(cardinality)            ?
-     .InSequence(sequences)         *
-     .After(expectations)           *
-     .WillOnce(action)              *
-     .WillRepeatedly(action)        ?
-     .RetiresOnSaturation();        ?
-```
-
-For each item above, `?` means it can be used at most once, while `*` means it
-can be used any number of times.
-
-In order to pass, `EXPECT_CALL` must be used before the calls are actually made.
-
-The `(matchers)` is a comma-separated list of matchers that correspond to each
-of the arguments of `method`, and sets the expectation only for calls of
-`method` that matches all of the matchers.
-
-If `(matchers)` is omitted, the expectation is the same as if the matchers were
-set to anything matchers (for example, `(_, _, _, _)` for a four-arg method).
-
-If `Times()` is omitted, the cardinality is assumed to be:
-
-*   `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
-*   `Times(n)` when there are `n` `WillOnce()`s but no `WillRepeatedly()`, where
-    `n` >= 1; or
-*   `Times(AtLeast(n))` when there are `n` `WillOnce()`s and a
-    `WillRepeatedly()`, where `n` >= 0.
-
-A method with no `EXPECT_CALL()` is free to be invoked *any number of times*,
-and the default action will be taken each time.
-
-### Matchers {#MatcherList}
-
-<!-- GOOGLETEST_CM0020 DO NOT DELETE -->
-
-A **matcher** matches a *single* argument. You can use it inside `ON_CALL()` or
-`EXPECT_CALL()`, or use it to validate a value directly using two macros:
-
-<!-- mdformat off(github rendering does not support multiline tables) -->
-| Macro                                | Description                           |
-| :----------------------------------- | :------------------------------------ |
-| `EXPECT_THAT(actual_value, matcher)` | Asserts that `actual_value` matches `matcher`. |
-| `ASSERT_THAT(actual_value, matcher)` | The same as `EXPECT_THAT(actual_value, matcher)`, except that it generates a **fatal** failure. |
-<!-- mdformat on -->
-
-Built-in matchers (where `argument` is the function argument, e.g.
-`actual_value` in the example above, or when used in the context of
-`EXPECT_CALL(mock_object, method(matchers))`, the arguments of `method`) are
-divided into several categories:
-
-#### Wildcard
-
-Matcher                     | Description
-:-------------------------- | :-----------------------------------------------
-`_`                         | `argument` can be any value of the correct type.
-`A<type>()` or `An<type>()` | `argument` can be any value of type `type`.
-
-#### Generic Comparison
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                | Description                                         |
-| :--------------------- | :-------------------------------------------------- |
-| `Eq(value)` or `value` | `argument == value`                                 |
-| `Ge(value)`            | `argument >= value`                                 |
-| `Gt(value)`            | `argument > value`                                  |
-| `Le(value)`            | `argument <= value`                                 |
-| `Lt(value)`            | `argument < value`                                  |
-| `Ne(value)`            | `argument != value`                                 |
-| `IsFalse()`            | `argument` evaluates to `false` in a Boolean context. |
-| `IsTrue()`             | `argument` evaluates to `true` in a Boolean context. |
-| `IsNull()`             | `argument` is a `NULL` pointer (raw or smart).      |
-| `NotNull()`            | `argument` is a non-null pointer (raw or smart).    |
-| `Optional(m)`          | `argument` is `optional<>` that contains a value matching `m`. |
-| `VariantWith<T>(m)`    | `argument` is `variant<>` that holds the alternative of type T with a value matching `m`. |
-| `Ref(variable)`        | `argument` is a reference to `variable`.            |
-| `TypedEq<type>(value)` | `argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded. |
-<!-- mdformat on -->
-
-Except `Ref()`, these matchers make a *copy* of `value` in case it's modified or
-destructed later. If the compiler complains that `value` doesn't have a public
-copy constructor, try wrap it in `ByRef()`, e.g.
-`Eq(ByRef(non_copyable_value))`. If you do that, make sure `non_copyable_value`
-is not changed afterwards, or the meaning of your matcher will be changed.
-
-#### Floating-Point Matchers {#FpMatchers}
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                          | Description                        |
-| :------------------------------- | :--------------------------------- |
-| `DoubleEq(a_double)`             | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal. |
-| `FloatEq(a_float)`               | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
-| `NanSensitiveDoubleEq(a_double)` | `argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
-| `NanSensitiveFloatEq(a_float)`   | `argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
-<!-- mdformat on -->
-
-The above matchers use ULP-based comparison (the same as used in googletest).
-They automatically pick a reasonable error bound based on the absolute value of
-the expected value. `DoubleEq()` and `FloatEq()` conform to the IEEE standard,
-which requires comparing two NaNs for equality to return false. The
-`NanSensitive*` version instead treats two NaNs as equal, which is often what a
-user wants.
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                                           | Description              |
-| :------------------------------------------------ | :----------------------- |
-| `DoubleNear(a_double, max_abs_error)`             | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
-| `FloatNear(a_float, max_abs_error)`               | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
-| `NanSensitiveDoubleNear(a_double, max_abs_error)` | `argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-| `NanSensitiveFloatNear(a_float, max_abs_error)`   | `argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
-<!-- mdformat on -->
-
-#### String Matchers
-
-The `argument` can be either a C string or a C++ string object:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                 | Description                                        |
-| :---------------------- | :------------------------------------------------- |
-| `ContainsRegex(string)` | `argument` matches the given regular expression.   |
-| `EndsWith(suffix)`      | `argument` ends with string `suffix`.              |
-| `HasSubstr(string)`     | `argument` contains `string` as a sub-string.      |
-| `MatchesRegex(string)`  | `argument` matches the given regular expression with the match starting at the first character and ending at the last character. |
-| `StartsWith(prefix)`    | `argument` starts with string `prefix`.            |
-| `StrCaseEq(string)`     | `argument` is equal to `string`, ignoring case.    |
-| `StrCaseNe(string)`     | `argument` is not equal to `string`, ignoring case. |
-| `StrEq(string)`         | `argument` is equal to `string`.                   |
-| `StrNe(string)`         | `argument` is not equal to `string`.               |
-<!-- mdformat on -->
-
-`ContainsRegex()` and `MatchesRegex()` take ownership of the `RE` object. They
-use the regular expression syntax defined
-[here](../../googletest/docs/advanced.md#regular-expression-syntax).
-`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide strings as
-well.
-
-#### Container Matchers
-
-Most STL-style containers support `==`, so you can use `Eq(expected_container)`
-or simply `expected_container` to match a container exactly. If you want to
-write the elements in-line, match them more flexibly, or get more informative
-messages, you can use:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                                   | Description                      |
-| :---------------------------------------- | :------------------------------- |
-| `BeginEndDistanceIs(m)` | `argument` is a container whose `begin()` and `end()` iterators are separated by a number of increments matching `m`. E.g. `BeginEndDistanceIs(2)` or `BeginEndDistanceIs(Lt(2))`. For containers that define a `size()` method, `SizeIs(m)` may be more efficient. |
-| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
-| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
-| `Each(e)` | `argument` is a container where *every* element matches `e`, which can be either a value or a matcher. |
-| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the *i*-th element matches `ei`, which can be a value or a matcher. |
-| `ElementsAreArray({e0, e1, ..., en})`, `ElementsAreArray(a_container)`, `ElementsAreArray(begin, end)`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
-| `IsSubsetOf({e0, e1, ..., en})`, `IsSubsetOf(a_container)`, `IsSubsetOf(begin, end)`, `IsSubsetOf(array)`, or `IsSubsetOf(array, count)` | `argument` matches `UnorderedElementsAre(x0, x1, ..., xk)` for some subset `{x0, x1, ..., xk}` of the expected matchers. |
-| `IsSupersetOf({e0, e1, ..., en})`, `IsSupersetOf(a_container)`, `IsSupersetOf(begin, end)`, `IsSupersetOf(array)`, or `IsSupersetOf(array, count)` | Some subset of `argument` matches `UnorderedElementsAre(`expected matchers`)`. |
-| `Pointwise(m, container)`, `Pointwise(m, {e0, e1, ..., en})` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
-| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
-| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under *some* permutation of the elements, each element matches an `ei` (for a different `i`), which can be a value or a matcher. |
-| `UnorderedElementsAreArray({e0, e1, ..., en})`, `UnorderedElementsAreArray(a_container)`, `UnorderedElementsAreArray(begin, end)`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `UnorderedPointwise(m, container)`, `UnorderedPointwise(m, {e0, e1, ..., en})` | Like `Pointwise(m, container)`, but ignores the order of elements. |
-| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(ElementsAre(1, 2, 3))` verifies that `argument` contains elements 1, 2, and 3, ignoring order. |
-| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater(), ElementsAre(3, 2, 1))`. |
-<!-- mdformat on -->
-
-**Notes:**
-
-*   These matchers can also match:
-    1.  a native array passed by reference (e.g. in `Foo(const int (&a)[5])`),
-        and
-    2.  an array passed as a pointer and a count (e.g. in `Bar(const T* buffer,
-        int len)` -- see [Multi-argument Matchers](#MultiArgMatchers)).
-*   The array being matched may be multi-dimensional (i.e. its elements can be
-    arrays).
-*   `m` in `Pointwise(m, ...)` should be a matcher for `::std::tuple<T, U>`
-    where `T` and `U` are the element type of the actual container and the
-    expected container, respectively. For example, to compare two `Foo`
-    containers where `Foo` doesn't support `operator==`, one might write:
-
-    ```cpp
-    using ::std::get;
-    MATCHER(FooEq, "") {
-      return std::get<0>(arg).Equals(std::get<1>(arg));
-    }
-    ...
-    EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
-    ```

-| :------------------------------ | :----------------------------------------- |
-| `Field(&class::field, m)`       | `argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |
-| `Key(e)`                        | `argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`. |
-| `Pair(m1, m2)`                  | `argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
-| `Property(&class::property, m)` | `argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_. |

-#### Multi-argument Matchers {#MultiArgMatchers}
-
-Technically, all matchers match a *single* value. A "multi-argument" matcher is
-just one that matches a *tuple*. The following matchers can be used to match a
-tuple `(x, y)`:
-
-Matcher | Description
-:------ | :----------
-`Eq()`  | `x == y`
-`Ge()`  | `x >= y`
-`Gt()`  | `x > y`
-`Le()`  | `x <= y`
-`Lt()`  | `x < y`
-`Ne()`  | `x != y`
-
-You can use the following selectors to pick a subset of the arguments (or
-reorder them) to participate in the matching:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                    | Description                                     |
-| :------------------------- | :---------------------------------------------- |
-| `AllArgs(m)`               | Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`. |
-| `Args<N1, N2, ..., Nk>(m)` | The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`. |
-<!-- mdformat on -->
-
-#### Composite Matchers
-
-You can make a matcher from one or more other matchers:
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher                          | Description                             |
-| :------------------------------- | :-------------------------------------- |
-| `AllOf(m1, m2, ..., mn)` | `argument` matches all of the matchers `m1` to `mn`. |
-| `AllOfArray({m0, m1, ..., mn})`, `AllOfArray(a_container)`, `AllOfArray(begin, end)`, `AllOfArray(array)`, or `AllOfArray(array, count)` | The same as `AllOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `AnyOf(m1, m2, ..., mn)` | `argument` matches at least one of the matchers `m1` to `mn`. |
-| `AnyOfArray({m0, m1, ..., mn})`, `AnyOfArray(a_container)`, `AnyOfArray(begin, end)`, `AnyOfArray(array)`, or `AnyOfArray(array, count)` | The same as `AnyOf()` except that the matchers come from an initializer list, STL-style container, iterator range, or C-style array. |
-| `Not(m)` | `argument` doesn't match matcher `m`. |

-| :---------------------- | :------------------------------------ |
-| `MatcherCast<T>(m)`     | casts matcher `m` to type `Matcher<T>`. |
-| `SafeMatcherCast<T>(m)` | [safely casts](cook_book.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
-| `Truly(predicate)`      | `predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor. |

-| `Matches(m)(value)` | evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor. |
-| `ExplainMatchResult(m, value, result_listener)` | evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |

-**Notes:**
-
-1.  The `MATCHER*` macros cannot be used inside a function or class.
-2.  The matcher body must be *purely functional* (i.e. it cannot have any side
-    effect, and the result must not depend on anything other than the value
-    being matched and the matcher parameters).
-3.  You can use `PrintToString(x)` to convert a value `x` of any type to a
-    string.

-### Actions {#ActionList}
-
-**Actions** specify what a mock function should do when invoked.
-
-#### Returning a Value
-
-<!-- mdformat off(no multiline tables) -->
-|                             |                                               |
-| :-------------------------- | :-------------------------------------------- |
-| `Return()`                  | Return from a `void` mock function.           |
-| `Return(value)`             | Return `value`. If the type of `value` is     different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed. |
-| `ReturnArg<N>()`            | Return the `N`-th (0-based) argument.         |
-| `ReturnNew<T>(a1, ..., ak)` | Return `new T(a1, ..., ak)`; a different      object is created each time. |
-| `ReturnNull()`              | Return a null pointer.                        |
-| `ReturnPointee(ptr)`        | Return the value pointed to by `ptr`.         |
-| `ReturnRef(variable)`       | Return a reference to `variable`.             |
-| `ReturnRefOfCopy(value)`    | Return a reference to a copy of `value`; the  copy lives as long as the action. |

-#### Side Effects
-
-<!-- mdformat off(no multiline tables) -->
-|                                    |                                         |
-| :--------------------------------- | :-------------------------------------- |
-| `Assign(&variable, value)` | Assign `value` to variable. |
-| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
-| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
-| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
-| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
-| `SetArgPointee<N>(value)` | Assign `value` to the variable pointed by the `N`-th (0-based) argument. |
-| `SetArgumentPointee<N>(value)` | Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0. |
-| `SetArrayArgument<N>(first, last)` | Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range. |
-| `SetErrnoAndReturn(error, value)` | Set `errno` to `error` and return `value`. |
-| `Throw(exception)` | Throws the given exception, which can be any copyable value. Available since v1.1.0. |

-
-#### Using a Function, Functor, or Lambda as an Action
-
-In the following, by "callable" we mean a free function, `std::function`,
-functor, or lambda.
-
-<!-- mdformat off(no multiline tables) -->
-|                                     |                                        |
-| :---------------------------------- | :------------------------------------- |
-| `f` | Invoke f with the arguments passed to the mock function, where f is a callable. |
-| `Invoke(f)` | Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor. |
-| `Invoke(object_pointer, &class::method)` | Invoke the method on the object with the arguments passed to the mock function. |
-| `InvokeWithoutArgs(f)` | Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
-| `InvokeWithoutArgs(object_pointer, &class::method)` | Invoke the method on the object, which takes no arguments. |
-| `InvokeArgument<N>(arg1, arg2, ..., argk)` | Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments. |
-<!-- mdformat on -->
-
-The return value of the invoked function is used as the return value of the
-action.
-
-When defining a callable to be used with `Invoke*()`, you can declare any unused
-parameters as `Unused`:
-
-```cpp
-using ::testing::Invoke;
-double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
-...
-EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
-```
-
-`Invoke(callback)` and `InvokeWithoutArgs(callback)` take ownership of
-`callback`, which must be permanent. The type of `callback` must be a base
-callback type instead of a derived one, e.g.
-
-```cpp
-  BlockingClosure* done = new BlockingClosure;
-  ... Invoke(done) ...;  // This won't compile!
-
-  Closure* done2 = new BlockingClosure;
-  ... Invoke(done2) ...;  // This works.
-```
-
-In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference,
-wrap it inside `ByRef()`. For example,
-
-```cpp
-using ::testing::ByRef;
-using ::testing::InvokeArgument;
-...
-InvokeArgument<2>(5, string("Hi"), ByRef(foo))
-```
-
-calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
-value, and `foo` by reference.
-
-#### Default Action
-
-<!-- mdformat off(no multiline tables) -->
-| Matcher       | Description                                            |
-| :------------ | :----------------------------------------------------- |
-| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
-<!-- mdformat on -->
-
-**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
-composite action - trying to do so will result in a run-time error.

-| :----------------------------- | :------------------------------------------ |
-| `DoAll(a1, a2, ..., an)`       | Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
-| `IgnoreResult(a)`              | Perform action `a` and ignore its result. `a` must not return void. |
-| `WithArg<N>(a)`                | Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
-| `WithArgs<N1, N2, ..., Nk>(a)` | Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
-| `WithoutArgs(a)`               | Perform action `a` without any arguments. |

-<!-- mdformat on -->
-
-The `ACTION*` macros cannot be used inside a function or class.
-
-### Cardinalities {#CardinalityList}
-
-These are used in `Times()` to specify how many times a mock function will be
-called:
-
-<!-- mdformat off(no multiline tables) -->
-|                   |                                                        |
-| :---------------- | :----------------------------------------------------- |
-| `AnyNumber()`     | The function can be called any number of times.        |
-| `AtLeast(n)`      | The call is expected at least `n` times.               |
-| `AtMost(n)`       | The call is expected at most `n` times.                |
-| `Between(m, n)`   | The call is expected between `m` and `n` (inclusive) times. |
-| `Exactly(n) or n` | The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0. |
-<!-- mdformat on -->
-
-### Expectation Order
-
-By default, the expectations can be matched in *any* order. If some or all
-expectations must be matched in a given order, there are two ways to specify it.
-They can be used either independently or together.
-
-#### The After Clause {#AfterClause}
-
-```cpp
-using ::testing::Expectation;
-...
-Expectation init_x = EXPECT_CALL(foo, InitX());
-Expectation init_y = EXPECT_CALL(foo, InitY());
-EXPECT_CALL(foo, Bar())
-     .After(init_x, init_y);
-```
-
-says that `Bar()` can be called only after both `InitX()` and `InitY()` have
-been called.
-
-If you don't know how many pre-requisites an expectation has when you write it,
-you can use an `ExpectationSet` to collect them:
-
-```cpp
-using ::testing::ExpectationSet;
-...
-ExpectationSet all_inits;
-for (int i = 0; i < element_count; i++) {
-  all_inits += EXPECT_CALL(foo, InitElement(i));
-}
-EXPECT_CALL(foo, Bar())
-     .After(all_inits);
-```
-
-says that `Bar()` can be called only after all elements have been initialized
-(but we don't care about which elements get initialized before the others).
-
-Modifying an `ExpectationSet` after using it in an `.After()` doesn't affect the
-meaning of the `.After()`.
-
-#### Sequences {#UsingSequences}
-
-When you have a long chain of sequential expectations, it's easier to specify
-the order using **sequences**, which don't require you to given each expectation
-in the chain a different name. *All expected calls* in the same sequence must
-occur in the order they are specified.
-
-```cpp
-using ::testing::Return;
-using ::testing::Sequence;
-Sequence s1, s2;
-...
-EXPECT_CALL(foo, Reset())
-    .InSequence(s1, s2)
-    .WillOnce(Return(true));
-EXPECT_CALL(foo, GetSize())
-    .InSequence(s1)
-    .WillOnce(Return(1));
-EXPECT_CALL(foo, Describe(A<const char*>()))
-    .InSequence(s2)
-    .WillOnce(Return("dummy"));
-```
-
-says that `Reset()` must be called before *both* `GetSize()` *and* `Describe()`,
-and the latter two can occur in any order.
-
-To put many expectations in a sequence conveniently:
-
-```cpp
-using ::testing::InSequence;
-{
-  InSequence seq;
-
-  EXPECT_CALL(...)...;
-  EXPECT_CALL(...)...;
-  ...
-  EXPECT_CALL(...)...;
-}
-```
-
-says that all expected calls in the scope of `seq` must occur in strict order.
-The name `seq` is irrelevant.
-
-### Verifying and Resetting a Mock
-
-gMock will verify the expectations on a mock object when it is destructed, or
-you can do it earlier:
-
-```cpp
-using ::testing::Mock;
-...
-// Verifies and removes the expectations on mock_obj;
-// returns true if and only if successful.
-Mock::VerifyAndClearExpectations(&mock_obj);
-...
-// Verifies and removes the expectations on mock_obj;
-// also removes the default actions set by ON_CALL();
-// returns true if and only if successful.
-Mock::VerifyAndClear(&mock_obj);
-```
-
-You can also tell gMock that a mock object can be leaked and doesn't need to be
-verified:
-
-```cpp
-Mock::AllowLeak(&mock_obj);
-```
-
-### Mock Classes
-
-gMock defines a convenient mock class template
-
-```cpp
-class MockFunction<R(A1, ..., An)> {
- public:
-  MOCK_METHOD(R, Call, (A1, ..., An));
-};
-```
-
-See this [recipe](cook_book.md#using-check-points) for one application of it.

-<!-- GOOGLETEST_CM0013 DO NOT DELETE -->
-
-### What Is gMock?
-
-When you write a prototype or test, often it's not feasible or wise to rely on
-real objects entirely. A **mock object** implements the same interface as a real
-object (so it can be used as one), but lets you specify at run time how it will
-be used and what it should do (which methods will be called? in which order? how
-many times? with what arguments? what will they return? etc).
-
-**Note:** It is easy to confuse the term *fake objects* with mock objects. Fakes
-and mocks actually mean very different things in the Test-Driven Development
-(TDD) community:
-
-*   **Fake** objects have working implementations, but usually take some
-    shortcut (perhaps to make the operations less expensive), which makes them
-    not suitable for production. An in-memory file system would be an example of
-    a fake.
-*   **Mocks** are objects pre-programmed with *expectations*, which form a
-    specification of the calls they are expected to receive.
-
-If all this seems too abstract for you, don't worry - the most important thing
-to remember is that a mock allows you to check the *interaction* between itself
-and code that uses it. The difference between fakes and mocks shall become much
-clearer once you start to use mocks.
-
-**gMock** is a library (sometimes we also call it a "framework" to make it sound
-cool) for creating mock classes and using them. It does to C++ what
-jMock/EasyMock does to Java (well, more or less).
-
-When using gMock,
-
-1.  first, you use some simple macros to describe the interface you want to
-    mock, and they will expand to the implementation of your mock class;
-2.  next, you create some mock objects and specify its expectations and behavior
-    using an intuitive syntax;
-3.  then you exercise code that uses the mock objects. gMock will catch any
-    violation to the expectations as soon as it arises.
-
-### Why gMock?
-
-While mock objects help you remove unnecessary dependencies in tests and make
-them fast and reliable, using mocks manually in C++ is *hard*:
-
-*   Someone has to implement the mocks. The job is usually tedious and
-    error-prone. No wonder people go great distance to avoid it.
-*   The quality of those manually written mocks is a bit, uh, unpredictable. You
-    may see some really polished ones, but you may also see some that were
-    hacked up in a hurry and have all sorts of ad hoc restrictions.
-*   The knowledge you gained from using one mock doesn't transfer to the next
-    one.
-
-In contrast, Java and Python programmers have some fine mock frameworks (jMock,
-EasyMock, [Mox](http://wtf/mox), etc), which automate the creation of mocks. As
-a result, mocking is a proven effective technique and widely adopted practice in
-those communities. Having the right tool absolutely makes the difference.
-
-gMock was built to help C++ programmers. It was inspired by jMock and EasyMock,
-but designed with C++'s specifics in mind. It is your friend if any of the
-following problems is bothering you:
-
-*   You are stuck with a sub-optimal design and wish you had done more
-    prototyping before it was too late, but prototyping in C++ is by no means
-    "rapid".
-*   Your tests are slow as they depend on too many libraries or use expensive
-    resources (e.g. a database).
-*   Your tests are brittle as some resources they use are unreliable (e.g. the
-    network).
-*   You want to test how your code handles a failure (e.g. a file checksum
-    error), but it's not easy to cause one.
-*   You need to make sure that your module interacts with other modules in the
-    right way, but it's hard to observe the interaction; therefore you resort to
-    observing the side effects at the end of the action, but it's awkward at
-    best.
-*   You want to "mock out" your dependencies, except that they don't have mock
-    implementations yet; and, frankly, you aren't thrilled by some of those
-    hand-written mocks.
-
-We encourage you to use gMock as
-
-*   a *design* tool, for it lets you experiment with your interface design early
-    and often. More iterations lead to better designs!
-*   a *testing* tool to cut your tests' outbound dependencies and probe the
-    interaction between your module and its collaborators.
-
-### Getting Started
-
-gMock is bundled with googletest.
-
-### A Case for Mock Turtles
-
-Let's look at an example. Suppose you are developing a graphics program that
-relies on a [LOGO](http://en.wikipedia.org/wiki/Logo_programming_language)-like
-API for drawing. How would you test that it does the right thing? Well, you can
-run it and compare the screen with a golden screen snapshot, but let's admit it:
-tests like this are expensive to run and fragile (What if you just upgraded to a
-shiny new graphics card that has better anti-aliasing? Suddenly you have to
-update all your golden images.). It would be too painful if all your tests are
-like this. Fortunately, you learned about
-[Dependency Injection](http://en.wikipedia.org/wiki/Dependency_injection) and know the right thing
-to do: instead of having your application talk to the system API directly, wrap
-the API in an interface (say, `Turtle`) and code to that interface:
-
-```cpp
-class Turtle {
-  ...
-  virtual ~Turtle() {};
-  virtual void PenUp() = 0;
-  virtual void PenDown() = 0;
-  virtual void Forward(int distance) = 0;
-  virtual void Turn(int degrees) = 0;
-  virtual void GoTo(int x, int y) = 0;
-  virtual int GetX() const = 0;
-  virtual int GetY() const = 0;
-};
-```
-
-(Note that the destructor of `Turtle` **must** be virtual, as is the case for
-**all** classes you intend to inherit from - otherwise the destructor of the
-derived class will not be called when you delete an object through a base
-pointer, and you'll get corrupted program states like memory leaks.)
-
-You can control whether the turtle's movement will leave a trace using `PenUp()`
-and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and
-`GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the
-turtle.
-
-Your program will normally use a real implementation of this interface. In
-tests, you can use a mock implementation instead. This allows you to easily
-check what drawing primitives your program is calling, with what arguments, and
-in which order. Tests written this way are much more robust (they won't break
-because your new machine does anti-aliasing differently), easier to read and
-maintain (the intent of a test is expressed in the code, not in some binary
-images), and run *much, much faster*.
-
-### Writing the Mock Class
-
-If you are lucky, the mocks you need to use have already been implemented by
-some nice people. If, however, you find yourself in the position to write a mock
-class, relax - gMock turns this task into a fun game! (Well, almost.)
-
-#### How to Define It
-
-Using the `Turtle` interface as example, here are the simple steps you need to
-follow:
-
-*   Derive a class `MockTurtle` from `Turtle`.
-*   Take a *virtual* function of `Turtle` (while it's possible to
-    [mock non-virtual methods using templates](cook_book.md#MockingNonVirtualMethods),
-    it's much more involved).
-*   In the `public:` section of the child class, write `MOCK_METHOD();`
-*   Now comes the fun part: you take the function signature, cut-and-paste it
-    into the macro, and add two commas - one between the return type and the
-    name, another between the name and the argument list.
-*   If you're mocking a const method, add a 4th parameter containing `(const)`
-    (the parentheses are required).
-*   Since you're overriding a virtual method, we suggest adding the `override`
-    keyword. For const methods the 4th parameter becomes `(const, override)`,
-    for non-const methods just `(override)`. This isn't mandatory.
-*   Repeat until all virtual functions you want to mock are done. (It goes
-    without saying that *all* pure virtual methods in your abstract class must
-    be either mocked or overridden.)
-
-After the process, you should have something like:
-
-```cpp
-#include "gmock/gmock.h"  // Brings in gMock.
-
-class MockTurtle : public Turtle {
- public:
-  ...
-  MOCK_METHOD(void, PenUp, (), (override));
-  MOCK_METHOD(void, PenDown, (), (override));
-  MOCK_METHOD(void, Forward, (int distance), (override));
-  MOCK_METHOD(void, Turn, (int degrees), (override));
-  MOCK_METHOD(void, GoTo, (int x, int y), (override));
-  MOCK_METHOD(int, GetX, (), (const, override));
-  MOCK_METHOD(int, GetY, (), (const, override));
-};
-```
-
-You don't need to define these mock methods somewhere else - the `MOCK_METHOD`
-macro will generate the definitions for you. It's that simple!
-
-#### Where to Put It
-
-When you define a mock class, you need to decide where to put its definition.
-Some people put it in a `_test.cc`. This is fine when the interface being mocked
-(say, `Foo`) is owned by the same person or team. Otherwise, when the owner of
-`Foo` changes it, your test could break. (You can't really expect `Foo`'s
-maintainer to fix every test that uses `Foo`, can you?)
-
-So, the rule of thumb is: if you need to mock `Foo` and it's owned by others,
-define the mock class in `Foo`'s package (better, in a `testing` sub-package
-such that you can clearly separate production code and testing utilities), put
-it in a `.h` and a `cc_library`. Then everyone can reference them from their
-tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and
-only tests that depend on the changed methods need to be fixed.
-
-Another way to do it: you can introduce a thin layer `FooAdaptor` on top of
-`Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb
-changes in `Foo` much more easily. While this is more work initially, carefully
-choosing the adaptor interface can make your code easier to write and more
-readable (a net win in the long run), as you can choose `FooAdaptor` to fit your
-specific domain much better than `Foo` does.
-

-
-### Using Mocks in Tests
-
-Once you have a mock class, using it is easy. The typical work flow is:
-
-1.  Import the gMock names from the `testing` namespace such that you can use
-    them unqualified (You only have to do it once per file. Remember that
-    namespaces are a good idea.
-2.  Create some mock objects.
-3.  Specify your expectations on them (How many times will a method be called?
-    With what arguments? What should it do? etc.).
-4.  Exercise some code that uses the mocks; optionally, check the result using
-    googletest assertions. If a mock method is called more than expected or with
-    wrong arguments, you'll get an error immediately.
-5.  When a mock is destructed, gMock will automatically check whether all
-    expectations on it have been satisfied.
-
-Here's an example:
-
-```cpp
-#include "path/to/mock-turtle.h"
-#include "gmock/gmock.h"
-#include "gtest/gtest.h"
-
-using ::testing::AtLeast;                         // #1
-
-TEST(PainterTest, CanDrawSomething) {
-  MockTurtle turtle;                              // #2
-  EXPECT_CALL(turtle, PenDown())                  // #3
-      .Times(AtLeast(1));
-
-  Painter painter(&turtle);                       // #4
-
-  EXPECT_TRUE(painter.DrawCircle(0, 0, 10));      // #5
-}
-```
-
-As you might have guessed, this test checks that `PenDown()` is called at least
-once. If the `painter` object didn't call this method, your test will fail with
-a message like this:
-
-```text
-path/to/my_test.cc:119: Failure
-Actual function call count doesn't match this expectation:
-Actually: never called;
-Expected: called at least once.
-Stack trace:
-...
-```
-
-**Tip 1:** If you run the test from an Emacs buffer, you can hit <Enter> on the
-line number to jump right to the failed expectation.
-
-**Tip 2:** If your mock objects are never deleted, the final verification won't
-happen. Therefore it's a good idea to turn on the heap checker in your tests
-when you allocate mocks on the heap. You get that automatically if you use the
-`gtest_main` library already.
-
-**Important note:** gMock requires expectations to be set **before** the mock
-functions are called, otherwise the behavior is **undefined**. In particular,
-you mustn't interleave `EXPECT_CALL()s` and calls to the mock functions.
-
-This means `EXPECT_CALL()` should be read as expecting that a call will occur
-*in the future*, not that a call has occurred. Why does gMock work like that?
-Well, specifying the expectation beforehand allows gMock to report a violation
-as soon as it rises, when the context (stack trace, etc) is still available.
-This makes debugging much easier.
-
-Admittedly, this test is contrived and doesn't do much. You can easily achieve
-the same effect without using gMock. However, as we shall reveal soon, gMock
-allows you to do *so much more* with the mocks.
-
-### Setting Expectations
-
-The key to using a mock object successfully is to set the *right expectations*
-on it. If you set the expectations too strict, your test will fail as the result
-of unrelated changes. If you set them too loose, bugs can slip through. You want
-to do it just right such that your test can catch exactly the kind of bugs you
-intend it to catch. gMock provides the necessary means for you to do it "just
-right."
-
-#### General Syntax
-
-In gMock we use the `EXPECT_CALL()` macro to set an expectation on a mock
-method. The general syntax is:
-
-```cpp
-EXPECT_CALL(mock_object, method(matchers))
-    .Times(cardinality)
-    .WillOnce(action)
-    .WillRepeatedly(action);
-```
-
-The macro has two arguments: first the mock object, and then the method and its
-arguments. Note that the two are separated by a comma (`,`), not a period (`.`).
-(Why using a comma? The answer is that it was necessary for technical reasons.)
-If the method is not overloaded, the macro can also be called without matchers:
-
-```cpp
-EXPECT_CALL(mock_object, non-overloaded-method)
-    .Times(cardinality)
-    .WillOnce(action)
-    .WillRepeatedly(action);
-```
-
-This syntax allows the test writer to specify "called with any arguments"
-without explicitly specifying the number or types of arguments. To avoid
-unintended ambiguity, this syntax may only be used for methods which are not
-overloaded
-
-Either form of the macro can be followed by some optional *clauses* that provide
-more information about the expectation. We'll discuss how each clause works in
-the coming sections.
-
-This syntax is designed to make an expectation read like English. For example,
-you can probably guess that
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-    .Times(5)
-    .WillOnce(Return(100))
-    .WillOnce(Return(150))
-    .WillRepeatedly(Return(200));
-```
-
-says that the `turtle` object's `GetX()` method will be called five times, it
-will return 100 the first time, 150 the second time, and then 200 every time.
-Some people like to call this style of syntax a Domain-Specific Language (DSL).
-
-**Note:** Why do we use a macro to do this? Well it serves two purposes: first
-it makes expectations easily identifiable (either by `gsearch` or by a human
-reader), and second it allows gMock to include the source file location of a
-failed expectation in messages, making debugging easier.
-
-#### Matchers: What Arguments Do We Expect?
-
-When a mock function takes arguments, we may specify what arguments we are
-expecting, for example:
-
-```cpp
-// Expects the turtle to move forward by 100 units.
-EXPECT_CALL(turtle, Forward(100));
-```
-
-Oftentimes you do not want to be too specific. Remember that talk about tests
-being too rigid? Over specification leads to brittle tests and obscures the
-intent of tests. Therefore we encourage you to specify only what's necessary—no
-more, no less. If you aren't interested in the value of an argument, write `_`
-as the argument, which means "anything goes":
-
-```cpp
-using ::testing::_;
-...
-// Expects that the turtle jumps to somewhere on the x=50 line.
-EXPECT_CALL(turtle, GoTo(50, _));
-```
-
-`_` is an instance of what we call **matchers**. A matcher is like a predicate
-and can test whether an argument is what we'd expect. You can use a matcher
-inside `EXPECT_CALL()` wherever a function argument is expected. `_` is a
-convenient way of saying "any value".
-
-In the above examples, `100` and `50` are also matchers; implicitly, they are
-the same as `Eq(100)` and `Eq(50)`, which specify that the argument must be
-equal (using `operator==`) to the matcher argument. There are many
-[built-in matchers](#MatcherList) for common types (as well as
-[custom matchers](cook_book.md#NewMatchers)); for example:
-
-```cpp
-using ::testing::Ge;
-...
-// Expects the turtle moves forward by at least 100.
-EXPECT_CALL(turtle, Forward(Ge(100)));
-```
-
-If you don't care about *any* arguments, rather than specify `_` for each of
-them you may instead omit the parameter list:
-
-```cpp
-// Expects the turtle to move forward.
-EXPECT_CALL(turtle, Forward);
-// Expects the turtle to jump somewhere.
-EXPECT_CALL(turtle, GoTo);
-```
-
-This works for all non-overloaded methods; if a method is overloaded, you need
-to help gMock resolve which overload is expected by specifying the number of
-arguments and possibly also the
-[types of the arguments](cook_book.md#SelectOverload).
-
-#### Cardinalities: How Many Times Will It Be Called?
-
-The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We
-call its argument a **cardinality** as it tells *how many times* the call should
-occur. It allows us to repeat an expectation many times without actually writing
-it as many times. More importantly, a cardinality can be "fuzzy", just like a
-matcher can be. This allows a user to express the intent of a test exactly.
-
-An interesting special case is when we say `Times(0)`. You may have guessed - it
-means that the function shouldn't be called with the given arguments at all, and
-gMock will report a googletest failure whenever the function is (wrongfully)
-called.
-
-We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the
-list of built-in cardinalities you can use, see
-[here](cheat_sheet.md#CardinalityList).
-
-The `Times()` clause can be omitted. **If you omit `Times()`, gMock will infer
-the cardinality for you.** The rules are easy to remember:
-
-*   If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the
-    `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
-*   If there are *n* `WillOnce()`'s but **no** `WillRepeatedly()`, where *n* >=
-    1, the cardinality is `Times(n)`.
-*   If there are *n* `WillOnce()`'s and **one** `WillRepeatedly()`, where *n* >=
-    0, the cardinality is `Times(AtLeast(n))`.
-
-**Quick quiz:** what do you think will happen if a function is expected to be
-called twice but actually called four times?
-
-#### Actions: What Should It Do?
-
-Remember that a mock object doesn't really have a working implementation? We as
-users have to tell it what to do when a method is invoked. This is easy in
-gMock.
-
-First, if the return type of a mock function is a built-in type or a pointer,
-the function has a **default action** (a `void` function will just return, a
-`bool` function will return `false`, and other functions will return 0). In
-addition, in C++ 11 and above, a mock function whose return type is
-default-constructible (i.e. has a default constructor) has a default action of
-returning a default-constructed value. If you don't say anything, this behavior
-will be used.
-
-Second, if a mock function doesn't have a default action, or the default action
-doesn't suit you, you can specify the action to be taken each time the
-expectation matches using a series of `WillOnce()` clauses followed by an
-optional `WillRepeatedly()`. For example,
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetX())
-     .WillOnce(Return(100))
-     .WillOnce(Return(200))
-     .WillOnce(Return(300));
-```
-
-says that `turtle.GetX()` will be called *exactly three times* (gMock inferred
-this from how many `WillOnce()` clauses we've written, since we didn't
-explicitly write `Times()`), and will return 100, 200, and 300 respectively.
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-     .WillOnce(Return(100))
-     .WillOnce(Return(200))
-     .WillRepeatedly(Return(300));
-```
-
-says that `turtle.GetY()` will be called *at least twice* (gMock knows this as
-we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no
-explicit `Times()`), will return 100 and 200 respectively the first two times,
-and 300 from the third time on.
-
-Of course, if you explicitly write a `Times()`, gMock will not try to infer the
-cardinality itself. What if the number you specified is larger than there are
-`WillOnce()` clauses? Well, after all `WillOnce()`s are used up, gMock will do
-the *default* action for the function every time (unless, of course, you have a
-`WillRepeatedly()`.).
-
-What can we do inside `WillOnce()` besides `Return()`? You can return a
-reference using `ReturnRef(*variable*)`, or invoke a pre-defined function, among
-[others](cook_book.md#using-actions).
-
-**Important note:** The `EXPECT_CALL()` statement evaluates the action clause
-only once, even though the action may be performed many times. Therefore you
-must be careful about side effects. The following may not do what you want:
-
-```cpp
-using ::testing::Return;
-...
-int n = 100;
-EXPECT_CALL(turtle, GetX())
-    .Times(4)
-    .WillRepeatedly(Return(n++));
-```
-
-Instead of returning 100, 101, 102, ..., consecutively, this mock function will
-always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)`
-will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will
-return the same pointer every time. If you want the side effect to happen every
-time, you need to define a custom action, which we'll teach in the
-[cook book](http://<!-- GOOGLETEST_CM0012 DO NOT DELETE -->).
-
-Time for another quiz! What do you think the following means?
-
-```cpp
-using ::testing::Return;
-...
-EXPECT_CALL(turtle, GetY())
-    .Times(4)
-    .WillOnce(Return(100));
-```
-
-Obviously `turtle.GetY()` is expected to be called four times. But if you think
-it will return 100 every time, think twice! Remember that one `WillOnce()`
-clause will be consumed each time the function is invoked and the default action
-will be taken afterwards. So the right answer is that `turtle.GetY()` will
-return 100 the first time, but **return 0 from the second time on**, as
-returning 0 is the default action for `int` functions.
-
-#### Using Multiple Expectations {#MultiExpectations}
-
-So far we've only shown examples where you have a single expectation. More
-realistically, you'll specify expectations on multiple mock methods which may be
-from multiple mock objects.
-
-By default, when a mock method is invoked, gMock will search the expectations in
-the **reverse order** they are defined, and stop when an active expectation that
-matches the arguments is found (you can think of it as "newer rules override
-older ones."). If the matching expectation cannot take any more calls, you will
-get an upper-bound-violated failure. Here's an example:
-
-```cpp
-using ::testing::_;
-...
-EXPECT_CALL(turtle, Forward(_));  // #1
-EXPECT_CALL(turtle, Forward(10))  // #2
-    .Times(2);
-```
-
-If `Forward(10)` is called three times in a row, the third time it will be an
-error, as the last matching expectation (#2) has been saturated. If, however,
-the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK,
-as now #1 will be the matching expectation.
-
-**Note:** Why does gMock search for a match in the *reverse* order of the
-expectations? The reason is that this allows a user to set up the default
-expectations in a mock object's constructor or the test fixture's set-up phase
-and then customize the mock by writing more specific expectations in the test
-body. So, if you have two expectations on the same method, you want to put the
-one with more specific matchers **after** the other, or the more specific rule
-would be shadowed by the more general one that comes after it.
-
-**Tip:** It is very common to start with a catch-all expectation for a method
-and `Times(AnyNumber())` (omitting arguments, or with `_` for all arguments, if
-overloaded). This makes any calls to the method expected. This is not necessary
-for methods that are not mentioned at all (these are "uninteresting"), but is
-useful for methods that have some expectations, but for which other calls are
-ok. See
-[Understanding Uninteresting vs Unexpected Calls](cook_book.md#uninteresting-vs-unexpected).
-
-#### Ordered vs Unordered Calls {#OrderedCalls}
-
-By default, an expectation can match a call even though an earlier expectation
-hasn't been satisfied. In other words, the calls don't have to occur in the
-order the expectations are specified.
-
-Sometimes, you may want all the expected calls to occur in a strict order. To
-say this in gMock is easy:
-
-```cpp
-using ::testing::InSequence;
-...
-TEST(FooTest, DrawsLineSegment) {
-  ...
-  {
-    InSequence seq;
-
-    EXPECT_CALL(turtle, PenDown());
-    EXPECT_CALL(turtle, Forward(100));
-    EXPECT_CALL(turtle, PenUp());
-  }
-  Foo();
-}
-```
-
-By creating an object of type `InSequence`, all expectations in its scope are
-put into a *sequence* and have to occur *sequentially*. Since we are just
-relying on the constructor and destructor of this object to do the actual work,
-its name is really irrelevant.
-
-In this example, we test that `Foo()` calls the three expected functions in the
-order as written. If a call is made out-of-order, it will be an error.
-
-(What if you care about the relative order of some of the calls, but not all of
-them? Can you specify an arbitrary partial order? The answer is ... yes! The
-details can be found [here](cook_book.md#OrderedCalls).)
-
-#### All Expectations Are Sticky (Unless Said Otherwise) {#StickyExpectations}
-
-Now let's do a quick quiz to see how well you can use this mock stuff already.
-How would you test that the turtle is asked to go to the origin *exactly twice*
-(you want to ignore any other instructions it receives)?
-
-After you've come up with your answer, take a look at ours and compare notes
-(solve it yourself first - don't cheat!):
-
-```cpp
-using ::testing::_;
-using ::testing::AnyNumber;
-...
-EXPECT_CALL(turtle, GoTo(_, _))  // #1
-     .Times(AnyNumber());
-EXPECT_CALL(turtle, GoTo(0, 0))  // #2
-     .Times(2);
-```
-
-Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, gMock will
-see that the arguments match expectation #2 (remember that we always pick the
-last matching expectation). Now, since we said that there should be only two
-such calls, gMock will report an error immediately. This is basically what we've
-told you in the [Using Multiple Expectations](#MultiExpectations) section above.
-
-This example shows that **expectations in gMock are "sticky" by default**, in
-the sense that they remain active even after we have reached their invocation
-upper bounds. This is an important rule to remember, as it affects the meaning
-of the spec, and is **different** to how it's done in many other mocking
-frameworks (Why'd we do that? Because we think our rule makes the common cases
-easier to express and understand.).
-
-Simple? Let's see if you've really understood it: what does the following code
-say?
-
-```cpp
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-      .WillOnce(Return(10*i));
-}
-```
-
-If you think it says that `turtle.GetX()` will be called `n` times and will
-return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we
-said, expectations are sticky. So, the second time `turtle.GetX()` is called,
-the last (latest) `EXPECT_CALL()` statement will match, and will immediately
-lead to an "upper bound violated" error - this piece of code is not very useful!
-
-One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is
-to explicitly say that the expectations are *not* sticky. In other words, they
-should *retire* as soon as they are saturated:
-
-```cpp
-using ::testing::Return;
-...
-for (int i = n; i > 0; i--) {
-  EXPECT_CALL(turtle, GetX())
-      .WillOnce(Return(10*i))
-      .RetiresOnSaturation();
-}
-```
-
-And, there's a better way to do it: in this case, we expect the calls to occur
-in a specific order, and we line up the actions to match the order. Since the
-order is important here, we should make it explicit using a sequence:
-
-```cpp
-using ::testing::InSequence;
-using ::testing::Return;
-...
-{
-  InSequence s;
-
-  for (int i = 1; i <= n; i++) {
-    EXPECT_CALL(turtle, GetX())
-        .WillOnce(Return(10*i))
-        .RetiresOnSaturation();
-  }
-}
-```
-
-By the way, the other situation where an expectation may *not* be sticky is when
-it's in a sequence - as soon as another expectation that comes after it in the
-sequence has been used, it automatically retires (and will never be used to
-match any call).
-
-#### Uninteresting Calls
-
-A mock object may have many methods, and not all of them are that interesting.
-For example, in some tests we may not care about how many times `GetX()` and
-`GetY()` get called.
-
-In gMock, if you are not interested in a method, just don't say anything about
-it. If a call to this method occurs, you'll see a warning in the test output,
-but it won't be a failure. This is called "naggy" behavior; to change, see
-[The Nice, the Strict, and the Naggy](cook_book.md#NiceStrictNaggy).

-## Legacy gMock FAQ {#GMockFaq}
-
-<!-- GOOGLETEST_CM0021 DO NOT DELETE -->
-
-### When I call a method on my mock object, the method for the real object is invoked instead. What's the problem?
-
-In order for a method to be mocked, it must be *virtual*, unless you use the
-[high-perf dependency injection technique](#MockingNonVirtualMethods).
-
-### Can I mock a variadic function?
-
-You cannot mock a variadic function (i.e. a function taking ellipsis (`...`)
-arguments) directly in gMock.
-
-The problem is that in general, there is *no way* for a mock object to know how
-many arguments are passed to the variadic method, and what the arguments' types
-are. Only the *author of the base class* knows the protocol, and we cannot look
-into his or her head.
-
-Therefore, to mock such a function, the *user* must teach the mock object how to
-figure out the number of arguments and their types. One way to do it is to
-provide overloaded versions of the function.
-
-Ellipsis arguments are inherited from C and not really a C++ feature. They are
-unsafe to use and don't work with arguments that have constructors or
-destructors. Therefore we recommend to avoid them in C++ as much as possible.
-
-### MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why?
-
-If you compile this using Microsoft Visual C++ 2005 SP1:
-
-```cpp
-class Foo {
-  ...
-  virtual void Bar(const int i) = 0;
-};
-
-class MockFoo : public Foo {
-  ...
-  MOCK_METHOD(void, Bar, (const int i), (override));
-};
-```
-
-You may get the following warning:
-
-```shell
-warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
-```
-
-This is a MSVC bug. The same code compiles fine with gcc, for example. If you
-use Visual C++ 2008 SP1, you would get the warning:
-
-```shell
-warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
-```
-
-In C++, if you *declare* a function with a `const` parameter, the `const`
-modifier is ignored. Therefore, the `Foo` base class above is equivalent to:
-
-```cpp
-class Foo {
-  ...
-  virtual void Bar(int i) = 0;  // int or const int?  Makes no difference.
-};
-```
-
-In fact, you can *declare* `Bar()` with an `int` parameter, and define it with a
-`const int` parameter. The compiler will still match them up.
-
-Since making a parameter `const` is meaningless in the method declaration, we
-recommend to remove it in both `Foo` and `MockFoo`. That should workaround the
-VC bug.
-
-Note that we are talking about the *top-level* `const` modifier here. If the
-function parameter is passed by pointer or reference, declaring the pointee or
-referee as `const` is still meaningful. For example, the following two
-declarations are *not* equivalent:
-
-```cpp
-void Bar(int* p);         // Neither p nor *p is const.
-void Bar(const int* p);  // p is not const, but *p is.
-```

-
-### I can't figure out why gMock thinks my expectations are not satisfied. What should I do?
-
-You might want to run your test with `--gmock_verbose=info`. This flag lets
-gMock print a trace of every mock function call it receives. By studying the
-trace, you'll gain insights on why the expectations you set are not met.
-
-If you see the message "The mock function has no default action set, and its
-return type has no default value set.", then try
-[adding a default action](for_dummies.md#DefaultValue). Due to a known issue,
-unexpected calls on mocks without default actions don't print out a detailed
-comparison between the actual arguments and the expected arguments.
-
-### My program crashed and `ScopedMockLog` spit out tons of messages. Is it a gMock bug?
-
-gMock and `ScopedMockLog` are likely doing the right thing here.
-
-When a test crashes, the failure signal handler will try to log a lot of
-information (the stack trace, and the address map, for example). The messages
-are compounded if you have many threads with depth stacks. When `ScopedMockLog`
-intercepts these messages and finds that they don't match any expectations, it
-prints an error for each of them.
-
-You can learn to ignore the errors, or you can rewrite your expectations to make
-your test more robust, for example, by adding something like:
-
-```cpp
-using ::testing::AnyNumber;
-using ::testing::Not;
-...
-  // Ignores any log not done by us.
-  EXPECT_CALL(log, Log(_, Not(EndsWith("/my_file.cc")), _))
-      .Times(AnyNumber());
-```
-
-### How can I assert that a function is NEVER called?
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .Times(0);
-```
-
-<!-- GOOGLETEST_CM0031 DO NOT DELETE -->
-
-### I have a failed test where gMock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant?
-
-When gMock detects a failure, it prints relevant information (the mock function
-arguments, the state of relevant expectations, and etc) to help the user debug.
-If another failure is detected, gMock will do the same, including printing the
-state of relevant expectations.
-
-Sometimes an expectation's state didn't change between two failures, and you'll
-see the same description of the state twice. They are however *not* redundant,
-as they refer to *different points in time*. The fact they are the same *is*
-interesting information.
-
-### I get a heapcheck failure when using a mock object, but using a real object is fine. What can be wrong?
-
-Does the class (hopefully a pure interface) you are mocking have a virtual
-destructor?
-
-Whenever you derive from a base class, make sure its destructor is virtual.
-Otherwise Bad Things will happen. Consider the following code:
-
-```cpp
-class Base {
- public:
-  // Not virtual, but should be.
-  ~Base() { ... }
-  ...
-};
-
-class Derived : public Base {
- public:
-  ...
- private:
-  std::string value_;
-};
-
-...
-  Base* p = new Derived;
-  ...
-  delete p;  // Surprise! ~Base() will be called, but ~Derived() will not
-                 // - value_ is leaked.
-```
-
-By changing `~Base()` to virtual, `~Derived()` will be correctly called when
-`delete p` is executed, and the heap checker will be happy.
-
-### The "newer expectations override older ones" rule makes writing expectations awkward. Why does gMock do that?
-
-When people complain about this, often they are referring to code like:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.  However, I have to write the expectations in the
-  // reverse order.  This sucks big time!!!
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(2))
-      .RetiresOnSaturation();
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(1))
-      .RetiresOnSaturation();
-```
-
-The problem, is that they didn't pick the **best** way to express the test's
-intent.
-
-By default, expectations don't have to be matched in *any* particular order. If
-you want them to match in a certain order, you need to be explicit. This is
-gMock's (and jMock's) fundamental philosophy: it's easy to accidentally
-over-specify your tests, and we want to make it harder to do so.
-
-There are two better ways to write the test spec. You could either put the
-expectations in sequence:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.  Using a sequence, we can write the expectations
-  // in their natural order.
-  {
-    InSequence s;
-    EXPECT_CALL(foo, Bar())
-        .WillOnce(Return(1))
-        .RetiresOnSaturation();
-    EXPECT_CALL(foo, Bar())
-        .WillOnce(Return(2))
-        .RetiresOnSaturation();
-  }
-```
-
-or you can put the sequence of actions in the same expectation:
-
-```cpp
-using ::testing::Return;
-...
-  // foo.Bar() should be called twice, return 1 the first time, and return
-  // 2 the second time.
-  EXPECT_CALL(foo, Bar())
-      .WillOnce(Return(1))
-      .WillOnce(Return(2))
-      .RetiresOnSaturation();
-```
-
-Back to the original questions: why does gMock search the expectations (and
-`ON_CALL`s) from back to front? Because this allows a user to set up a mock's
-behavior for the common case early (e.g. in the mock's constructor or the test
-fixture's set-up phase) and customize it with more specific rules later. If
-gMock searches from front to back, this very useful pattern won't be possible.
-
-### gMock prints a warning when a function without EXPECT_CALL is called, even if I have set its behavior using ON_CALL. Would it be reasonable not to show the warning in this case?
-
-When choosing between being neat and being safe, we lean toward the latter. So
-the answer is that we think it's better to show the warning.
-
-Often people write `ON_CALL`s in the mock object's constructor or `SetUp()`, as
-the default behavior rarely changes from test to test. Then in the test body
-they set the expectations, which are often different for each test. Having an
-`ON_CALL` in the set-up part of a test doesn't mean that the calls are expected.
-If there's no `EXPECT_CALL` and the method is called, it's possibly an error. If
-we quietly let the call go through without notifying the user, bugs may creep in
-unnoticed.
-
-If, however, you are sure that the calls are OK, you can write
-
-```cpp
-using ::testing::_;
-...
-  EXPECT_CALL(foo, Bar(_))
-      .WillRepeatedly(...);
-```
-
-instead of
-
-```cpp
-using ::testing::_;
-...
-  ON_CALL(foo, Bar(_))
-      .WillByDefault(...);
-```
-
-This tells gMock that you do expect the calls and no warning should be printed.
-
-Also, you can control the verbosity by specifying `--gmock_verbose=error`. Other
-values are `info` and `warning`. If you find the output too noisy when
-debugging, just choose a less verbose level.
-
-### How can I delete the mock function's argument in an action?
-
-If your mock function takes a pointer argument and you want to delete that
-argument, you can use testing::DeleteArg<N>() to delete the N'th (zero-indexed)
-argument:
-
-```cpp
-using ::testing::_;
-  ...
-  MOCK_METHOD(void, Bar, (X* x, const Y& y));
-  ...
-  EXPECT_CALL(mock_foo_, Bar(_, _))
-      .WillOnce(testing::DeleteArg<0>()));
-```
-
-### How can I perform an arbitrary action on a mock function's argument?
-
-If you find yourself needing to perform some action that's not supported by
-gMock directly, remember that you can define your own actions using
-[`MakeAction()`](#NewMonoActions) or
-[`MakePolymorphicAction()`](#NewPolyActions), or you can write a stub function
-and invoke it using [`Invoke()`](#FunctionsAsActions).
-
-```cpp
-using ::testing::_;
-using ::testing::Invoke;
-  ...
-  MOCK_METHOD(void, Bar, (X* p));
-  ...
-  EXPECT_CALL(mock_foo_, Bar(_))
-      .WillOnce(Invoke(MyAction(...)));
-```
-
-### My code calls a static/global function. Can I mock it?
-
-You can, but you need to make some changes.
-
-In general, if you find yourself needing to mock a static function, it's a sign
-that your modules are too tightly coupled (and less flexible, less reusable,
-less testable, etc). You are probably better off defining a small interface and
-call the function through that interface, which then can be easily mocked. It's
-a bit of work initially, but usually pays for itself quickly.
-
-This Google Testing Blog
-[post](https://testing.googleblog.com/2008/06/defeat-static-cling.html) says it
-excellently. Check it out.
-
-### My mock object needs to do complex stuff. It's a lot of pain to specify the actions. gMock sucks!
-
-I know it's not a question, but you get an answer for free any way. :-)
-
-With gMock, you can create mocks in C++ easily. And people might be tempted to
-use them everywhere. Sometimes they work great, and sometimes you may find them,
-well, a pain to use. So, what's wrong in the latter case?
-
-When you write a test without using mocks, you exercise the code and assert that
-it returns the correct value or that the system is in an expected state. This is
-sometimes called "state-based testing".
-
-Mocks are great for what some call "interaction-based" testing: instead of
-checking the system state at the very end, mock objects verify that they are
-invoked the right way and report an error as soon as it arises, giving you a
-handle on the precise context in which the error was triggered. This is often
-more effective and economical to do than state-based testing.
-
-If you are doing state-based testing and using a test double just to simulate
-the real object, you are probably better off using a fake. Using a mock in this
-case causes pain, as it's not a strong point for mocks to perform complex
-actions. If you experience this and think that mocks suck, you are just not
-using the right tool for your problem. Or, you might be trying to solve the
-wrong problem. :-)
-
-### I got a warning "Uninteresting function call encountered - default action taken.." Should I panic?
-
-By all means, NO! It's just an FYI. :-)
-
-What it means is that you have a mock function, you haven't set any expectations
-on it (by gMock's rule this means that you are not interested in calls to this
-function and therefore it can be called any number of times), and it is called.
-That's OK - you didn't say it's not OK to call the function!
-
-What if you actually meant to disallow this function to be called, but forgot to
-write `EXPECT_CALL(foo, Bar()).Times(0)`? While one can argue that it's the
-user's fault, gMock tries to be nice and prints you a note.
-
-So, when you see the message and believe that there shouldn't be any
-uninteresting calls, you should investigate what's going on. To make your life
-easier, gMock dumps the stack trace when an uninteresting call is encountered.
-From that you can figure out which mock function it is, and how it is called.
-
-### I want to define a custom action. Should I use Invoke() or implement the ActionInterface interface?
-
-Either way is fine - you want to choose the one that's more convenient for your
-circumstance.
-
-Usually, if your action is for a particular function type, defining it using
-`Invoke()` should be easier; if your action can be used in functions of
-different types (e.g. if you are defining `Return(*value*)`),
-`MakePolymorphicAction()` is easiest. Sometimes you want precise control on what
-types of functions the action can be used in, and implementing `ActionInterface`
-is the way to go here. See the implementation of `Return()` in
-`testing/base/public/gmock-actions.h` for an example.
-
-### I use SetArgPointee() in WillOnce(), but gcc complains about "conflicting return type specified". What does it mean?
-
-You got this error as gMock has no idea what value it should return when the
-mock method is called. `SetArgPointee()` says what the side effect is, but
-doesn't say what the return value should be. You need `DoAll()` to chain a
-`SetArgPointee()` with a `Return()` that provides a value appropriate to the API
-being mocked.
-
-See this [recipe](cook_book.md#mocking-side-effects) for more details and an
-example.
-
-### I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do?
-
-We've noticed that when the `/clr` compiler flag is used, Visual C++ uses 5~6
-times as much memory when compiling a mock class. We suggest to avoid `/clr`
-when compiling native C++ mocks.

-### Generic Build Instructions
-
-#### Setup
-
-To build Google Test and your tests that use it, you need to tell your build
-system where to find its headers and source files. The exact way to do it
-depends on which build system you use, and is usually straightforward.
-
-### Build with CMake
-
-Google Test comes with a CMake build script (
-[CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
-that can be used on a wide range of platforms ("C" stands for cross-platform.).
-If you don't have CMake installed already, you can download it for free from
-<http://www.cmake.org/>.
-
-CMake works by generating native makefiles or build projects that can be used in
-the compiler environment of your choice. You can either build Google Test as a
-standalone project or it can be incorporated into an existing CMake build for
-another project.
-
-#### Standalone CMake Project
-
-When building Google Test as a standalone project, the typical workflow starts
-with:
-
-    mkdir mybuild       # Create a directory to hold the build output.
-    cd mybuild
-    cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the last command
-with
-
-    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a \*nix system, you should now see a Makefile in the current
-directory. Just type 'make' to build gtest.
-
-If you use Windows and have Visual Studio installed, a `gtest.sln` file and
-several `.vcproj` files will be created. You can then build them using Visual
-Studio.
-
-On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
-
-#### Incorporating Into An Existing CMake Project
-
-If you want to use gtest in a project which already uses CMake, then a more
-robust and flexible approach is to build gtest as part of that project directly.
-This is done by making the GoogleTest source code available to the main build
-and adding it using CMake's `add_subdirectory()` command. This has the
-significant advantage that the same compiler and linker settings are used
-between gtest and the rest of your project, so issues associated with using
-incompatible libraries (eg debug/release), etc. are avoided. This is
-particularly useful on Windows. Making GoogleTest's source code available to the
-main build can be done a few different ways:
-
-*   Download the GoogleTest source code manually and place it at a known
-    location. This is the least flexible approach and can make it more difficult
-    to use with continuous integration systems, etc.
-*   Embed the GoogleTest source code as a direct copy in the main project's
-    source tree. This is often the simplest approach, but is also the hardest to
-    keep up to date. Some organizations may not permit this method.
-*   Add GoogleTest as a git submodule or equivalent. This may not always be
-    possible or appropriate. Git submodules, for example, have their own set of
-    advantages and drawbacks.
-*   Use CMake to download GoogleTest as part of the build's configure step. This
-    is just a little more complex, but doesn't have the limitations of the other
-    methods.
-
-The last of the above methods is implemented with a small piece of CMake code in
-a separate file (e.g. `CMakeLists.txt.in`) which is copied to the build area and
-then invoked as a sub-build _during the CMake stage_. That directory is then
-pulled into the main build with `add_subdirectory()`. For example:
-
-New file `CMakeLists.txt.in`:
-
-```cmake
-cmake_minimum_required(VERSION 2.8.2)
-
-project(googletest-download NONE)
-
-include(ExternalProject)
-ExternalProject_Add(googletest
-  GIT_REPOSITORY    https://github.com/google/googletest.git
-  GIT_TAG           master
-  SOURCE_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-src"
-  BINARY_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-build"
-  CONFIGURE_COMMAND ""
-  BUILD_COMMAND     ""
-  INSTALL_COMMAND   ""
-  TEST_COMMAND      ""
-)
-```
-
-Existing build's `CMakeLists.txt`:
-
-```cmake
-# Download and unpack googletest at configure time
-configure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)
-execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
-  RESULT_VARIABLE result
-  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
-if(result)
-  message(FATAL_ERROR "CMake step for googletest failed: ${result}")
-endif()
-execute_process(COMMAND ${CMAKE_COMMAND} --build .
-  RESULT_VARIABLE result
-  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
-if(result)
-  message(FATAL_ERROR "Build step for googletest failed: ${result}")
-endif()
-
-# Prevent overriding the parent project's compiler/linker
-# settings on Windows
-set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
-
-# Add googletest directly to our build. This defines
-# the gtest and gtest_main targets.
-add_subdirectory(${CMAKE_CURRENT_BINARY_DIR}/googletest-src
-                 ${CMAKE_CURRENT_BINARY_DIR}/googletest-build
-                 EXCLUDE_FROM_ALL)
-
-# The gtest/gtest_main targets carry header search path
-# dependencies automatically when using CMake 2.8.11 or
-# later. Otherwise we have to add them here ourselves.
-if (CMAKE_VERSION VERSION_LESS 2.8.11)
-  include_directories("${gtest_SOURCE_DIR}/include")
-endif()
-
-# Now simply link against gtest or gtest_main as needed. Eg
-add_executable(example example.cpp)
-target_link_libraries(example gtest_main)
-add_test(NAME example_test COMMAND example)
-```
-
-Note that this approach requires CMake 2.8.2 or later due to its use of the
-`ExternalProject_Add()` command. The above technique is discussed in more detail
-in [this separate article](http://crascit.com/2015/07/25/cmake-gtest/) which
-also contains a link to a fully generalized implementation of the technique.
-
-##### Visual Studio Dynamic vs Static Runtimes
-
-By default, new Visual Studio projects link the C runtimes dynamically but
-Google Test links them statically. This will generate an error that looks
-something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
-detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
-'MDd_DynamicDebug' in main.obj
-
-Google Test already has a CMake option for this: `gtest_force_shared_crt`
-
-Enabling this option will make gtest link the runtimes dynamically too, and
-match the project in which it is included.
-
-#### C++ Standard Version
-
-An environment that supports C++11 is required in order to successfully build
-Google Test. One way to ensure this is to specify the standard in the top-level
-project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
-is not feasible, for example in a C project using Google Test for validation,
-then it can be specified by adding it to the options for cmake via the
-`DCMAKE_CXX_FLAGS` option.
-
-### Tweaking Google Test
-
-Google Test can be used in diverse environments. The default configuration may
-not work (or may not work well) out of the box in some environments. However,
-you can easily tweak Google Test by defining control macros on the compiler
-command line. Generally, these macros are named like `GTEST_XYZ` and you define
-them to either 1 or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below. For a complete list, see file
-[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).
-
-### Multi-threaded Tests
-
-Google Test is thread-safe where the pthread library is available. After
-`#include "gtest/gtest.h"`, you can check the
-`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
-`#defined` to 1, no if it's undefined.).
-
-If Google Test doesn't correctly detect whether pthread is available in your
-environment, you can force it with
-
-    -DGTEST_HAS_PTHREAD=1
-
-or
-
-    -DGTEST_HAS_PTHREAD=0
-
-When Google Test uses pthread, you may need to add flags to your compiler and/or
-linker to select the pthread library, or you'll get link errors. If you use the
-CMake script or the deprecated Autotools script, this is taken care of for you.
-If you use your own build script, you'll need to read your compiler and linker's
-manual to figure out what flags to add.
-
-### As a Shared Library (DLL)
-
-Google Test is compact, so most users can build and link it as a static library
-for the simplicity. You can choose to use Google Test as a shared library (known
-as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-    -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags. You'll also need to tell the linker to produce a shared
-library instead - consult your linker's manual for how to do it.
-
-To compile your *tests* that use the gtest shared library, add
-
-    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when using some
-compilers (e.g. GCC), they may become necessary in the future, if we decide to
-improve the speed of loading the library (see
-<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
-to always add the above flags when using Google Test as a shared library.
-Otherwise a future release of Google Test may break your build script.
-
-### Avoiding Macro Name Clashes
-
-In C++, macros don't obey namespaces. Therefore two libraries that both define a
-macro of the same name will clash if you `#include` both definitions. In case a
-Google Test macro clashes with another library, you can force Google Test to
-rename its macro to avoid the conflict.
-
-Specifically, if both Google Test and some other code define macro FOO, you can
-add
-
-    -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell Google Test to change the macro's name from `FOO`
-to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For
-example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
-
-    GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-    TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.

-## Why should test suite names and test names not contain underscore?
-
-Underscore (`_`) is special, as C++ reserves the following to be used by the
-compiler and the standard library:
-
-1.  any identifier that starts with an `_` followed by an upper-case letter, and
-2.  any identifier that contains two consecutive underscores (i.e. `__`)
-    *anywhere* in its name.
-
-User code is *prohibited* from using such identifiers.
-
-Now let's look at what this means for `TEST` and `TEST_F`.
-
-Currently `TEST(TestSuiteName, TestName)` generates a class named
-`TestSuiteName_TestName_Test`. What happens if `TestSuiteName` or `TestName`
-contains `_`?
-
-1.  If `TestSuiteName` starts with an `_` followed by an upper-case letter (say,
-    `_Foo`), we end up with `_Foo_TestName_Test`, which is reserved and thus
-    invalid.
-2.  If `TestSuiteName` ends with an `_` (say, `Foo_`), we get
-    `Foo__TestName_Test`, which is invalid.
-3.  If `TestName` starts with an `_` (say, `_Bar`), we get
-    `TestSuiteName__Bar_Test`, which is invalid.
-4.  If `TestName` ends with an `_` (say, `Bar_`), we get
-    `TestSuiteName_Bar__Test`, which is invalid.
-
-So clearly `TestSuiteName` and `TestName` cannot start or end with `_`
-(Actually, `TestSuiteName` can start with `_` -- as long as the `_` isn't
-followed by an upper-case letter. But that's getting complicated. So for
-simplicity we just say that it cannot start with `_`.).
-
-It may seem fine for `TestSuiteName` and `TestName` to contain `_` in the
-middle. However, consider this:
-
-```c++
-TEST(Time, Flies_Like_An_Arrow) { ... }
-TEST(Time_Flies, Like_An_Arrow) { ... }
-```
-
-Now, the two `TEST`s will both generate the same class
-(`Time_Flies_Like_An_Arrow_Test`). That's not good.
-
-So for simplicity, we just ask the users to avoid `_` in `TestSuiteName` and
-`TestName`. The rule is more constraining than necessary, but it's simple and
-easy to remember. It also gives googletest some wiggle room in case its
-implementation needs to change in the future.
-
-If you violate the rule, there may not be immediate consequences, but your test
-may (just may) break with a new compiler (or a new version of the compiler you
-are using) or with a new version of googletest. Therefore it's best to follow
-the rule.
-
-## Why does googletest support `EXPECT_EQ(NULL, ptr)` and `ASSERT_EQ(NULL, ptr)` but not `EXPECT_NE(NULL, ptr)` and `ASSERT_NE(NULL, ptr)`?
-
-First of all you can use `EXPECT_NE(nullptr, ptr)` and `ASSERT_NE(nullptr,
-ptr)`. This is the preferred syntax in the style guide because nullptr does not
-have the type problems that NULL does. Which is why NULL does not work.
-
-Due to some peculiarity of C++, it requires some non-trivial template meta
-programming tricks to support using `NULL` as an argument of the `EXPECT_XX()`
-and `ASSERT_XX()` macros. Therefore we only do it where it's most needed
-(otherwise we make the implementation of googletest harder to maintain and more
-error-prone than necessary).
-
-The `EXPECT_EQ()` macro takes the *expected* value as its first argument and the
-*actual* value as the second. It's reasonable that someone wants to write
-`EXPECT_EQ(NULL, some_expression)`, and this indeed was requested several times.
-Therefore we implemented it.
-
-The need for `EXPECT_NE(NULL, ptr)` isn't nearly as strong. When the assertion
-fails, you already know that `ptr` must be `NULL`, so it doesn't add any
-information to print `ptr` in this case. That means `EXPECT_TRUE(ptr != NULL)`
-works just as well.
-
-If we were to support `EXPECT_NE(NULL, ptr)`, for consistency we'll have to
-support `EXPECT_NE(ptr, NULL)` as well, as unlike `EXPECT_EQ`, we don't have a
-convention on the order of the two arguments for `EXPECT_NE`. This means using
-the template meta programming tricks twice in the implementation, making it even
-harder to understand and maintain. We believe the benefit doesn't justify the
-cost.
-
-Finally, with the growth of the gMock matcher library, we are encouraging people
-to use the unified `EXPECT_THAT(value, matcher)` syntax more often in tests. One
-significant advantage of the matcher approach is that matchers can be easily
-combined to form new matchers, while the `EXPECT_NE`, etc, macros cannot be
-easily combined. Therefore we want to invest more in the matchers than in the
-`EXPECT_XX()` macros.
-
-## I need to test that different implementations of an interface satisfy some common requirements. Should I use typed tests or value-parameterized tests?
-
-For testing various implementations of the same interface, either typed tests or
-value-parameterized tests can get it done. It's really up to you the user to
-decide which is more convenient for you, depending on your particular case. Some
-rough guidelines:
-
-*   Typed tests can be easier to write if instances of the different
-    implementations can be created the same way, modulo the type. For example,
-    if all these implementations have a public default constructor (such that
-    you can write `new TypeParam`), or if their factory functions have the same
-    form (e.g. `CreateInstance<TypeParam>()`).
-*   Value-parameterized tests can be easier to write if you need different code
-    patterns to create different implementations' instances, e.g. `new Foo` vs
-    `new Bar(5)`. To accommodate for the differences, you can write factory
-    function wrappers and pass these function pointers to the tests as their
-    parameters.
-*   When a typed test fails, the default output includes the name of the type,
-    which can help you quickly identify which implementation is wrong.
-    Value-parameterized tests only show the number of the failed iteration by
-    default. You will need to define a function that returns the iteration name
-    and pass it as the third parameter to INSTANTIATE_TEST_SUITE_P to have more
-    useful output.
-*   When using typed tests, you need to make sure you are testing against the
-    interface type, not the concrete types (in other words, you want to make
-    sure `implicit_cast<MyInterface*>(my_concrete_impl)` works, not just that
-    `my_concrete_impl` works). It's less likely to make mistakes in this area
-    when using value-parameterized tests.
-
-I hope I didn't confuse you more. :-) If you don't mind, I'd suggest you to give
-both approaches a try. Practice is a much better way to grasp the subtle
-differences between the two tools. Once you have some concrete experience, you
-can much more easily decide which one to use the next time.
-
-## I got some run-time errors about invalid proto descriptors when using `ProtocolMessageEquals`. Help!
-
-**Note:** `ProtocolMessageEquals` and `ProtocolMessageEquiv` are *deprecated*
-now. Please use `EqualsProto`, etc instead.
-
-`ProtocolMessageEquals` and `ProtocolMessageEquiv` were redefined recently and
-are now less tolerant of invalid protocol buffer definitions. In particular, if
-you have a `foo.proto` that doesn't fully qualify the type of a protocol message
-it references (e.g. `message<Bar>` where it should be `message<blah.Bar>`), you
-will now get run-time errors like:
-
-```
-... descriptor.cc:...] Invalid proto descriptor for file "path/to/foo.proto":
-... descriptor.cc:...]  blah.MyMessage.my_field: ".Bar" is not defined.
-```
-
-If you see this, your `.proto` file is broken and needs to be fixed by making
-the types fully qualified. The new definition of `ProtocolMessageEquals` and
-`ProtocolMessageEquiv` just happen to reveal your bug.
-
-## My death test modifies some state, but the change seems lost after the death test finishes. Why?
-
-Death tests (`EXPECT_DEATH`, etc) are executed in a sub-process s.t. the
-expected crash won't kill the test program (i.e. the parent process). As a
-result, any in-memory side effects they incur are observable in their respective
-sub-processes, but not in the parent process. You can think of them as running
-in a parallel universe, more or less.
-
-In particular, if you use mocking and the death test statement invokes some mock
-methods, the parent process will think the calls have never occurred. Therefore,
-you may want to move your `EXPECT_CALL` statements inside the `EXPECT_DEATH`
-macro.
-
-## EXPECT_EQ(htonl(blah), blah_blah) generates weird compiler errors in opt mode. Is this a googletest bug?
-
-Actually, the bug is in `htonl()`.
-
-According to `'man htonl'`, `htonl()` is a *function*, which means it's valid to
-use `htonl` as a function pointer. However, in opt mode `htonl()` is defined as
-a *macro*, which breaks this usage.
-
-Worse, the macro definition of `htonl()` uses a `gcc` extension and is *not*
-standard C++. That hacky implementation has some ad hoc limitations. In
-particular, it prevents you from writing `Foo<sizeof(htonl(x))>()`, where `Foo`
-is a template that has an integral argument.
-
-The implementation of `EXPECT_EQ(a, b)` uses `sizeof(... a ...)` inside a
-template argument, and thus doesn't compile in opt mode when `a` contains a call
-to `htonl()`. It is difficult to make `EXPECT_EQ` bypass the `htonl()` bug, as
-the solution must work with different compilers on various platforms.
-
-`htonl()` has some other problems as described in `//util/endian/endian.h`,
-which defines `ghtonl()` to replace it. `ghtonl()` does the same thing `htonl()`
-does, only without its problems. We suggest you to use `ghtonl()` instead of
-`htonl()`, both in your tests and production code.
-
-`//util/endian/endian.h` also defines `ghtons()`, which solves similar problems
-in `htons()`.
-
-Don't forget to add `//util/endian` to the list of dependencies in the `BUILD`
-file wherever `ghtonl()` and `ghtons()` are used. The library consists of a
-single header file and will not bloat your binary.
-
-## The compiler complains about "undefined references" to some static const member variables, but I did define them in the class body. What's wrong?
-
-If your class has a static data member:
-
-```c++
-// foo.h
-class Foo {
-  ...
-  static const int kBar = 100;
-};
-```
-
-You also need to define it *outside* of the class body in `foo.cc`:
-
-```c++
-const int Foo::kBar;  // No initializer here.
-```
-
-Otherwise your code is **invalid C++**, and may break in unexpected ways. In
-particular, using it in googletest comparison assertions (`EXPECT_EQ`, etc) will
-generate an "undefined reference" linker error. The fact that "it used to work"
-doesn't mean it's valid. It just means that you were lucky. :-)
-
-## Can I derive a test fixture from another?
-
-Yes.
-
-Each test fixture has a corresponding and same named test suite. This means only
-one test suite can use a particular fixture. Sometimes, however, multiple test
-cases may want to use the same or slightly different fixtures. For example, you
-may want to make sure that all of a GUI library's test suites don't leak
-important system resources like fonts and brushes.
-
-In googletest, you share a fixture among test suites by putting the shared logic
-in a base test fixture, then deriving from that base a separate fixture for each
-test suite that wants to use this common logic. You then use `TEST_F()` to write
-tests using each derived fixture.
-
-Typically, your code looks like this:
-
-```c++
-// Defines a base test fixture.
-class BaseTest : public ::testing::Test {
- protected:
-  ...
-};
-
-// Derives a fixture FooTest from BaseTest.
-class FooTest : public BaseTest {
- protected:
-  void SetUp() override {
-    BaseTest::SetUp();  // Sets up the base fixture first.
-    ... additional set-up work ...
-  }
-
-  void TearDown() override {
-    ... clean-up work for FooTest ...
-    BaseTest::TearDown();  // Remember to tear down the base fixture
-                           // after cleaning up FooTest!
-  }
-
-  ... functions and variables for FooTest ...
-};
-
-// Tests that use the fixture FooTest.
-TEST_F(FooTest, Bar) { ... }
-TEST_F(FooTest, Baz) { ... }
-
-... additional fixtures derived from BaseTest ...
-```
-
-If necessary, you can continue to derive test fixtures from a derived fixture.
-googletest has no limit on how deep the hierarchy can be.
-
-For a complete example using derived test fixtures, see
-[sample5_unittest.cc](../samples/sample5_unittest.cc).
-
-## My compiler complains "void value not ignored as it ought to be." What does this mean?
-
-You're probably using an `ASSERT_*()` in a function that doesn't return `void`.
-`ASSERT_*()` can only be used in `void` functions, due to exceptions being
-disabled by our build system. Please see more details
-[here](advanced.md#assertion-placement).
-
-## My death test hangs (or seg-faults). How do I fix it?
-
-In googletest, death tests are run in a child process and the way they work is
-delicate. To write death tests you really need to understand how they work.
-Please make sure you have read [this](advanced.md#how-it-works).
-
-In particular, death tests don't like having multiple threads in the parent
-process. So the first thing you can try is to eliminate creating threads outside
-of `EXPECT_DEATH()`. For example, you may want to use mocks or fake objects
-instead of real ones in your tests.
-
-Sometimes this is impossible as some library you must use may be creating
-threads before `main()` is even reached. In this case, you can try to minimize
-the chance of conflicts by either moving as many activities as possible inside
-`EXPECT_DEATH()` (in the extreme case, you want to move everything inside), or
-leaving as few things as possible in it. Also, you can try to set the death test
-style to `"threadsafe"`, which is safer but slower, and see if it helps.
-
-If you go with thread-safe death tests, remember that they rerun the test
-program from the beginning in the child process. Therefore make sure your
-program can run side-by-side with itself and is deterministic.
-
-In the end, this boils down to good concurrent programming. You have to make
-sure that there is no race conditions or dead locks in your program. No silver
-bullet - sorry!
-
-## Should I use the constructor/destructor of the test fixture or SetUp()/TearDown()? {#CtorVsSetUp}
-
-The first thing to remember is that googletest does **not** reuse the same test
-fixture object across multiple tests. For each `TEST_F`, googletest will create
-a **fresh** test fixture object, immediately call `SetUp()`, run the test body,
-call `TearDown()`, and then delete the test fixture object.
-
-When you need to write per-test set-up and tear-down logic, you have the choice
-between using the test fixture constructor/destructor or `SetUp()/TearDown()`.
-The former is usually preferred, as it has the following benefits:
-
-*   By initializing a member variable in the constructor, we have the option to
-    make it `const`, which helps prevent accidental changes to its value and
-    makes the tests more obviously correct.
-*   In case we need to subclass the test fixture class, the subclass'
-    constructor is guaranteed to call the base class' constructor *first*, and
-    the subclass' destructor is guaranteed to call the base class' destructor
-    *afterward*. With `SetUp()/TearDown()`, a subclass may make the mistake of
-    forgetting to call the base class' `SetUp()/TearDown()` or call them at the
-    wrong time.
-
-You may still want to use `SetUp()/TearDown()` in the following cases:
-
-*   C++ does not allow virtual function calls in constructors and destructors.
-    You can call a method declared as virtual, but it will not use dynamic
-    dispatch, it will use the definition from the class the constructor of which
-    is currently executing. This is because calling a virtual method before the
-    derived class constructor has a chance to run is very dangerous - the
-    virtual method might operate on uninitialized data. Therefore, if you need
-    to call a method that will be overridden in a derived class, you have to use
-    `SetUp()/TearDown()`.
-*   In the body of a constructor (or destructor), it's not possible to use the
-    `ASSERT_xx` macros. Therefore, if the set-up operation could cause a fatal
-    test failure that should prevent the test from running, it's necessary to
-    use `abort` <!-- GOOGLETEST_CM0015 DO NOT DELETE --> and abort the whole test executable,
-    or to use `SetUp()` instead of a constructor.
-*   If the tear-down operation could throw an exception, you must use
-    `TearDown()` as opposed to the destructor, as throwing in a destructor leads
-    to undefined behavior and usually will kill your program right away. Note
-    that many standard libraries (like STL) may throw when exceptions are
-    enabled in the compiler. Therefore you should prefer `TearDown()` if you
-    want to write portable tests that work with or without exceptions.
-*   The googletest team is considering making the assertion macros throw on
-    platforms where exceptions are enabled (e.g. Windows, Mac OS, and Linux
-    client-side), which will eliminate the need for the user to propagate
-    failures from a subroutine to its caller. Therefore, you shouldn't use
-    googletest assertions in a destructor if your code could run on such a
-    platform.
-
-## The compiler complains "no matching function to call" when I use ASSERT_PRED*. How do I fix it?
-
-If the predicate function you use in `ASSERT_PRED*` or `EXPECT_PRED*` is
-overloaded or a template, the compiler will have trouble figuring out which
-overloaded version it should use. `ASSERT_PRED_FORMAT*` and
-`EXPECT_PRED_FORMAT*` don't have this problem.
-
-If you see this error, you might want to switch to
-`(ASSERT|EXPECT)_PRED_FORMAT*`, which will also give you a better failure
-message. If, however, that is not an option, you can resolve the problem by
-explicitly telling the compiler which version to pick.
-
-For example, suppose you have
-
-```c++
-bool IsPositive(int n) {
-  return n > 0;
-}
-
-bool IsPositive(double x) {
-  return x > 0;
-}
-```
-
-you will get a compiler error if you write
-
-```c++
-EXPECT_PRED1(IsPositive, 5);
-```
-
-However, this will work:
-
-```c++
-EXPECT_PRED1(static_cast<bool (*)(int)>(IsPositive), 5);
-```
-
-(The stuff inside the angled brackets for the `static_cast` operator is the type
-of the function pointer for the `int`-version of `IsPositive()`.)
-
-As another example, when you have a template function
-
-```c++
-template <typename T>
-bool IsNegative(T x) {
-  return x < 0;
-}
-```
-
-you can use it in a predicate assertion like this:
-
-```c++
-ASSERT_PRED1(IsNegative<int>, -5);
-```
-
-Things are more interesting if your template has more than one parameters. The
-following won't compile:
-
-```c++
-ASSERT_PRED2(GreaterThan<int, int>, 5, 0);
-```
-
-as the C++ pre-processor thinks you are giving `ASSERT_PRED2` 4 arguments, which
-is one more than expected. The workaround is to wrap the predicate function in
-parentheses:
-
-```c++
-ASSERT_PRED2((GreaterThan<int, int>), 5, 0);
-```
-
-## My compiler complains about "ignoring return value" when I call RUN_ALL_TESTS(). Why?
-
-Some people had been ignoring the return value of `RUN_ALL_TESTS()`. That is,
-instead of
-
-```c++
-  return RUN_ALL_TESTS();
-```
-
-they write
-
-```c++
-  RUN_ALL_TESTS();
-```
-
-This is **wrong and dangerous**. The testing services needs to see the return
-value of `RUN_ALL_TESTS()` in order to determine if a test has passed. If your
-`main()` function ignores it, your test will be considered successful even if it
-has a googletest assertion failure. Very bad.
-
-We have decided to fix this (thanks to Michael Chastain for the idea). Now, your
-code will no longer be able to ignore `RUN_ALL_TESTS()` when compiled with
-`gcc`. If you do so, you'll get a compiler error.
-
-If you see the compiler complaining about you ignoring the return value of
-`RUN_ALL_TESTS()`, the fix is simple: just make sure its value is used as the
-return value of `main()`.
-
-But how could we introduce a change that breaks existing tests? Well, in this
-case, the code was already broken in the first place, so we didn't break it. :-)
-
-## My compiler complains that a constructor (or destructor) cannot return a value. What's going on?
-
-Due to a peculiarity of C++, in order to support the syntax for streaming
-messages to an `ASSERT_*`, e.g.
-
-```c++
-  ASSERT_EQ(1, Foo()) << "blah blah" << foo;
-```
-
-we had to give up using `ASSERT*` and `FAIL*` (but not `EXPECT*` and
-`ADD_FAILURE*`) in constructors and destructors. The workaround is to move the
-content of your constructor/destructor to a private void member function, or
-switch to `EXPECT_*()` if that works. This
-[section](advanced.md#assertion-placement) in the user's guide explains it.
-
-## My SetUp() function is not called. Why?
-
-C++ is case-sensitive. Did you spell it as `Setup()`?
-
-Similarly, sometimes people spell `SetUpTestSuite()` as `SetupTestSuite()` and
-wonder why it's never called.
-
-
-## I have several test suites which share the same test fixture logic, do I have to define a new test fixture class for each of them? This seems pretty tedious.
-
-You don't have to. Instead of
-
-```c++
-class FooTest : public BaseTest {};
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-class BarTest : public BaseTest {};
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-you can simply `typedef` the test fixtures:
-
-```c++
-typedef BaseTest FooTest;
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-typedef BaseTest BarTest;
-
-TEST_F(BarTest, Abc) { ... }
-TEST_F(BarTest, Def) { ... }
-```
-
-## googletest output is buried in a whole bunch of LOG messages. What do I do?
-
-The googletest output is meant to be a concise and human-friendly report. If
-your test generates textual output itself, it will mix with the googletest
-output, making it hard to read. However, there is an easy solution to this
-problem.
-
-Since `LOG` messages go to stderr, we decided to let googletest output go to
-stdout. This way, you can easily separate the two using redirection. For
-example:
-
-```shell
-$ ./my_test > gtest_output.txt
-```
-
-## Why should I prefer test fixtures over global variables?
-
-There are several good reasons:
-
-1.  It's likely your test needs to change the states of its global variables.
-    This makes it difficult to keep side effects from escaping one test and
-    contaminating others, making debugging difficult. By using fixtures, each
-    test has a fresh set of variables that's different (but with the same
-    names). Thus, tests are kept independent of each other.
-2.  Global variables pollute the global namespace.
-3.  Test fixtures can be reused via subclassing, which cannot be done easily
-    with global variables. This is useful if many test suites have something in
-    common.
-
-## What can the statement argument in ASSERT_DEATH() be?
-
-`ASSERT_DEATH(*statement*, *regex*)` (or any death assertion macro) can be used
-wherever `*statement*` is valid. So basically `*statement*` can be any C++
-statement that makes sense in the current context. In particular, it can
-reference global and/or local variables, and can be:
-
-*   a simple function call (often the case),
-*   a complex expression, or
-*   a compound statement.
-
-Some examples are shown here:
-
-```c++
-// A death test can be a simple function call.
-TEST(MyDeathTest, FunctionCall) {
-  ASSERT_DEATH(Xyz(5), "Xyz failed");
-}
-
-// Or a complex expression that references variables and functions.
-TEST(MyDeathTest, ComplexExpression) {
-  const bool c = Condition();
-  ASSERT_DEATH((c ? Func1(0) : object2.Method("test")),
-               "(Func1|Method) failed");
-}
-
-// Death assertions can be used any where in a function.  In
-// particular, they can be inside a loop.
-TEST(MyDeathTest, InsideLoop) {
-  // Verifies that Foo(0), Foo(1), ..., and Foo(4) all die.
-  for (int i = 0; i < 5; i++) {
-    EXPECT_DEATH_M(Foo(i), "Foo has \\d+ errors",
-                   ::testing::Message() << "where i is " << i);
-  }
-}
-
-// A death assertion can contain a compound statement.
-TEST(MyDeathTest, CompoundStatement) {
-  // Verifies that at lease one of Bar(0), Bar(1), ..., and

-
-## I have a fixture class `FooTest`, but `TEST_F(FooTest, Bar)` gives me error ``"no matching function for call to `FooTest::FooTest()'"``. Why?
-
-Googletest needs to be able to create objects of your test fixture class, so it
-must have a default constructor. Normally the compiler will define one for you.
-However, there are cases where you have to define your own:
-
-*   If you explicitly declare a non-default constructor for class `FooTest`
-    (`DISALLOW_EVIL_CONSTRUCTORS()` does this), then you need to define a
-    default constructor, even if it would be empty.
-*   If `FooTest` has a const non-static data member, then you have to define the
-    default constructor *and* initialize the const member in the initializer
-    list of the constructor. (Early versions of `gcc` doesn't force you to
-    initialize the const member. It's a bug that has been fixed in `gcc 4`.)
-
-## Why does ASSERT_DEATH complain about previous threads that were already joined?
-
-With the Linux pthread library, there is no turning back once you cross the line
-from single thread to multiple threads. The first time you create a thread, a
-manager thread is created in addition, so you get 3, not 2, threads. Later when
-the thread you create joins the main thread, the thread count decrements by 1,
-but the manager thread will never be killed, so you still have 2 threads, which
-means you cannot safely run a death test.
-
-The new NPTL thread library doesn't suffer from this problem, as it doesn't
-create a manager thread. However, if you don't control which machine your test
-runs on, you shouldn't depend on this.
-
-## Why does googletest require the entire test suite, instead of individual tests, to be named *DeathTest when it uses ASSERT_DEATH?
-
-googletest does not interleave tests from different test suites. That is, it
-runs all tests in one test suite first, and then runs all tests in the next test
-suite, and so on. googletest does this because it needs to set up a test suite
-before the first test in it is run, and tear it down afterwords. Splitting up
-the test case would require multiple set-up and tear-down processes, which is
-inefficient and makes the semantics unclean.
-
-If we were to determine the order of tests based on test name instead of test
-case name, then we would have a problem with the following situation:
-
-```c++
-TEST_F(FooTest, AbcDeathTest) { ... }
-TEST_F(FooTest, Uvw) { ... }
-
-TEST_F(BarTest, DefDeathTest) { ... }
-TEST_F(BarTest, Xyz) { ... }
-```
-
-Since `FooTest.AbcDeathTest` needs to run before `BarTest.Xyz`, and we don't
-interleave tests from different test suites, we need to run all tests in the
-`FooTest` case before running any test in the `BarTest` case. This contradicts
-with the requirement to run `BarTest.DefDeathTest` before `FooTest.Uvw`.
-
-## But I don't like calling my entire test suite \*DeathTest when it contains both death tests and non-death tests. What do I do?
-
-You don't have to, but if you like, you may split up the test suite into
-`FooTest` and `FooDeathTest`, where the names make it clear that they are
-related:
-
-```c++
-class FooTest : public ::testing::Test { ... };
-
-TEST_F(FooTest, Abc) { ... }
-TEST_F(FooTest, Def) { ... }
-
-using FooDeathTest = FooTest;
-
-TEST_F(FooDeathTest, Uvw) { ... EXPECT_DEATH(...) ... }
-TEST_F(FooDeathTest, Xyz) { ... ASSERT_DEATH(...) ... }
-```
-
-## googletest prints the LOG messages in a death test's child process only when the test fails. How can I see the LOG messages when the death test succeeds?
-
-Printing the LOG messages generated by the statement inside `EXPECT_DEATH()`
-makes it harder to search for real problems in the parent's log. Therefore,
-googletest only prints them when the death test has failed.
-
-If you really need to see such LOG messages, a workaround is to temporarily
-break the death test (e.g. by changing the regex pattern it is expected to
-match). Admittedly, this is a hack. We'll consider a more permanent solution
-after the fork-and-exec-style death tests are implemented.
-
-## The compiler complains about "no match for 'operator<<'" when I use an assertion. What gives?
-
-If you use a user-defined type `FooType` in an assertion, you must make sure
-there is an `std::ostream& operator<<(std::ostream&, const FooType&)` function
-defined such that we can print a value of `FooType`.
-
-In addition, if `FooType` is declared in a name space, the `<<` operator also
-needs to be defined in the *same* name space. See https://abseil.io/tips/49 for details.
-
-## How do I suppress the memory leak messages on Windows?
-
-Since the statically initialized googletest singleton requires allocations on
-the heap, the Visual C++ memory leak detector will report memory leaks at the
-end of the program run. The easiest way to avoid this is to use the
-`_CrtMemCheckpoint` and `_CrtMemDumpAllObjectsSince` calls to not report any
-statically initialized heap objects. See MSDN for more details and additional
-heap check/debug routines.
-
-## How can my code detect if it is running in a test?
-
-If you write code that sniffs whether it's running in a test and does different
-things accordingly, you are leaking test-only logic into production code and
-there is no easy way to ensure that the test-only code paths aren't run by
-mistake in production. Such cleverness also leads to
-[Heisenbugs](https://en.wikipedia.org/wiki/Heisenbug). Therefore we strongly
-advise against the practice, and googletest doesn't provide a way to do it.
-
-In general, the recommended way to cause the code to behave differently under
-test is [Dependency Injection](https://en.wikipedia.org/wiki/Dependency_injection). You can inject
-different functionality from the test and from the production code. Since your
-production code doesn't link in the for-test logic at all (the
-[`testonly`](https://docs.bazel.build/versions/master/be/common-definitions.html#common.testonly) attribute for BUILD targets helps to ensure
-that), there is no danger in accidentally running it.
-
-However, if you *really*, *really*, *really* have no choice, and if you follow
-the rule of ending your test program names with `_test`, you can use the
-*horrible* hack of sniffing your executable name (`argv[0]` in `main()`) to know
-whether the code is under test.
-
-## How do I temporarily disable a test?
-
-If you have a broken test that you cannot fix right away, you can add the
-DISABLED_ prefix to its name. This will exclude it from execution. This is
-better than commenting out the code or using #if 0, as disabled tests are still
-compiled (and thus won't rot).
-
-To include disabled tests in test execution, just invoke the test program with
-the --gtest_also_run_disabled_tests flag.
-
-## Is it OK if I have two separate `TEST(Foo, Bar)` test methods defined in different namespaces?
-
-Yes.
-
-The rule is **all test methods in the same test suite must use the same fixture
-class.** This means that the following is **allowed** because both tests use the
-same fixture class (`::testing::Test`).
-
-```c++
-namespace foo {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-TEST(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar
-```
-
-However, the following code is **not allowed** and will produce a runtime error
-from googletest because the test methods are using different test fixture
-classes with the same test suite name.
-
-```c++
-namespace foo {
-class CoolTest : public ::testing::Test {};  // Fixture foo::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace foo
-
-namespace bar {
-class CoolTest : public ::testing::Test {};  // Fixture: bar::CoolTest
-TEST_F(CoolTest, DoSomething) {
-  SUCCEED();
-}
-}  // namespace bar

-## Using GoogleTest from various build systems
-
-GoogleTest comes with pkg-config files that can be used to determine all
-necessary flags for compiling and linking to GoogleTest (and GoogleMock).
-Pkg-config is a standardised plain-text format containing
-
-*   the includedir (-I) path
-*   necessary macro (-D) definitions
-*   further required flags (-pthread)
-*   the library (-L) path
-*   the library (-l) to link to
-
-All current build systems support pkg-config in one way or another. For all
-examples here we assume you want to compile the sample
-`samples/sample3_unittest.cc`.
-
-### CMake
-
-Using `pkg-config` in CMake is fairly easy:
-
-```cmake
-cmake_minimum_required(VERSION 3.0)
-
-cmake_policy(SET CMP0048 NEW)
-project(my_gtest_pkgconfig VERSION 0.0.1 LANGUAGES CXX)
-
-find_package(PkgConfig)
-pkg_search_module(GTEST REQUIRED gtest_main)
-
-add_executable(testapp samples/sample3_unittest.cc)
-target_link_libraries(testapp ${GTEST_LDFLAGS})
-target_compile_options(testapp PUBLIC ${GTEST_CFLAGS})
-
-include(CTest)
-add_test(first_and_only_test testapp)
-```
-
-It is generally recommended that you use `target_compile_options` + `_CFLAGS`
-over `target_include_directories` + `_INCLUDE_DIRS` as the former includes not
-just -I flags (GoogleTest might require a macro indicating to internal headers
-that all libraries have been compiled with threading enabled. In addition,
-GoogleTest might also require `-pthread` in the compiling step, and as such
-splitting the pkg-config `Cflags` variable into include dirs and macros for
-`target_compile_definitions()` might still miss this). The same recommendation
-goes for using `_LDFLAGS` over the more commonplace `_LIBRARIES`, which happens
-to discard `-L` flags and `-pthread`.
-
-### Autotools
-
-Finding GoogleTest in Autoconf and using it from Automake is also fairly easy:
-
-In your `configure.ac`:
-
-```
-AC_PREREQ([2.69])
-AC_INIT([my_gtest_pkgconfig], [0.0.1])
-AC_CONFIG_SRCDIR([samples/sample3_unittest.cc])
-AC_PROG_CXX
-
-PKG_CHECK_MODULES([GTEST], [gtest_main])
-
-AM_INIT_AUTOMAKE([foreign subdir-objects])
-AC_CONFIG_FILES([Makefile])
-AC_OUTPUT
-```
-
-and in your `Makefile.am`:
-
-```
-check_PROGRAMS = testapp
-TESTS = $(check_PROGRAMS)
-
-testapp_SOURCES = samples/sample3_unittest.cc
-testapp_CXXFLAGS = $(GTEST_CFLAGS)
-testapp_LDADD = $(GTEST_LIBS)
-```
-
-### Meson
-
-Meson natively uses pkgconfig to query dependencies:
-
-```
-project('my_gtest_pkgconfig', 'cpp', version : '0.0.1')
-
-gtest_dep = dependency('gtest_main')
-
-testapp = executable(
-  'testapp',
-  files(['samples/sample3_unittest.cc']),
-  dependencies : gtest_dep,
-  install : false)
-
-test('first_and_only_test', testapp)
-```
-
-### Plain Makefiles
-
-Since `pkg-config` is a small Unix command-line utility, it can be used in
-handwritten `Makefile`s too:
-
-```makefile
-GTEST_CFLAGS = `pkg-config --cflags gtest_main`
-GTEST_LIBS = `pkg-config --libs gtest_main`
-
-.PHONY: tests all
-
-tests: all
-  ./testapp
-
-all: testapp
-
-testapp: testapp.o
-  $(CXX) $(CXXFLAGS) $(LDFLAGS) $< -o $@ $(GTEST_LIBS)
-
-testapp.o: samples/sample3_unittest.cc
-  $(CXX) $(CPPFLAGS) $(CXXFLAGS) $< -c -o $@ $(GTEST_CFLAGS)
-```
-
-### Help! pkg-config can't find GoogleTest!
-
-Let's say you have a `CMakeLists.txt` along the lines of the one in this
-tutorial and you try to run `cmake`. It is very possible that you get a failure
-along the lines of:
-
-```
-- Checking for one of the modules 'gtest_main'
-CMake Error at /usr/share/cmake/Modules/FindPkgConfig.cmake:640 (message):
-  None of the required 'gtest_main' found
-```
-
-These failures are common if you installed GoogleTest yourself and have not
-sourced it from a distro or other package manager. If so, you need to tell
-pkg-config where it can find the `.pc` files containing the information. Say you
-installed GoogleTest to `/usr/local`, then it might be that the `.pc` files are
-installed under `/usr/local/lib64/pkgconfig`. If you set
-
-```
-export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
-```
-
-pkg-config will also try to look in `PKG_CONFIG_PATH` to find `gtest_main.pc`.
