# 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 contribution
rather than a GitHub Pull Request. If you are not able to submit internally, 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/issues).
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](#contributor-license-agreements)).
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](https://groups.google.com/group/googletestframework) and the
GitHub repository. Likewise, the Google Mock community exists primarily through
their own [discussion group](https://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/main/.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/) v3.6 or newer (for running some of the
tests and re-generating certain source files from templates)
* [CMake](https://cmake.org/) v2.8.12 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.

# GoogleTest
### Announcements
#### Live at Head
GoogleTest now follows the
[Abseil Live at Head philosophy](https://abseil.io/about/philosophy#upgrade-support).
We recommend
[updating to the latest commit in the `main` branch as often as possible](https://github.com/abseil/abseil-cpp/blob/master/FAQ.md#what-is-live-at-head-and-how-do-i-do-it).
We do publish occasional semantic versions, tagged with
`v${major}.${minor}.${patch}` (e.g. `v1.14.0`).
#### Documentation Updates
Our documentation is now live on GitHub Pages at
https://google.github.io/googletest/. We recommend browsing the documentation on
GitHub Pages rather than directly in the repository.
#### Release 1.14.0
[Release 1.14.0](https://github.com/google/googletest/releases/tag/v1.14.0) is
now available.
The 1.14.x branch requires at least C++14.
#### Continuous Integration
We use Google's internal systems for continuous integration. \
GitHub Actions were added for the convenience of open-source contributors. They
are exclusively maintained by the open-source community and not used by the
GoogleTest team.
#### Coming Soon
* We are planning to take a dependency on
[Abseil](https://github.com/abseil/abseil-cpp).
* More documentation improvements are planned.
## Welcome to **GoogleTest**, 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.
### Getting Started
See the [GoogleTest User's Guide](https://google.github.io/googletest/) for
documentation. We recommend starting with the
[GoogleTest Primer](https://google.github.io/googletest/primer.html).
More information about building GoogleTest can be found at
[googletest/README.md](googletest/README.md).
## Features
* xUnit test framework: \
Googletest is based on the [xUnit](https://en.wikipedia.org/wiki/XUnit)
testing framework, a popular architecture for unit testing
* Test discovery: \
Googletest automatically discovers and runs your tests, eliminating the need
to manually register your tests
* Rich set of assertions: \
Googletest provides a variety of assertions, such as equality, inequality,
exceptions, and more, making it easy to test your code
* User-defined assertions: \
You can define your own assertions with Googletest, making it simple to
write tests that are specific to your code
* Death tests: \
Googletest supports death tests, which verify that your code exits in a
certain way, making it useful for testing error-handling code
* Fatal and non-fatal failures: \
You can specify whether a test failure should be treated as fatal or
non-fatal with Googletest, allowing tests to continue running even if a
failure occurs
* Value-parameterized tests: \
Googletest supports value-parameterized tests, which run multiple times with
different input values, making it useful for testing functions that take
different inputs
* Type-parameterized tests: \
Googletest also supports type-parameterized tests, which run with different
data types, making it useful for testing functions that work with different
data types
* Various options for running tests: \
Googletest provides many options for running tests including running
individual tests, running tests in a specific order and running tests in
parallel
## Supported Platforms
GoogleTest follows Google's
[Foundational C++ Support Policy](https://opensource.google/documentation/policies/cplusplus-support).
See
[this table](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)
for a list of currently supported versions of compilers, platforms, and build
tools.
## Who Is Using GoogleTest?
In addition to many internal projects at Google, GoogleTest is also used by the
following notable projects:
* The [Chromium projects](https://www.chromium.org/) (behind the Chrome
browser and Chrome OS).
* The [LLVM](https://llvm.org/) compiler.
* [Protocol Buffers](https://github.com/google/protobuf), Google's data
interchange format.
* The [OpenCV](https://opencv.org/) computer vision library.

# gMock Cheat Sheet
## Defining a Mock Class
### Mocking a Normal Class {#MockClass}
Given
```cpp
class Foo {
public:
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 {
public:
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.
```
{: .callout .note}
**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 {
public:
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> {
public:
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
ON_CALL(foo, GetSize()) // #3
.WillByDefault(Return(1));
// ... other default actions ...
EXPECT_CALL(foo, Describe(5)) // #4
.Times(3)
.WillRepeatedly(Return("Category 5"));
// ... other expectations ...
EXPECT_EQ(MyProductionFunction(&foo), "good"); // #5
} // #6
```
## 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`, use
[`DefaultValue<T>`](reference/mocking.md#DefaultValue). For example:
```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 std::make_unique<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(buzz1, nullptr);
EXPECT_NE(buzz2, nullptr);
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`](reference/mocking.md#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
[Knowing When to Expect](gmock_cook_book.md#UseOnCall) for a more detailed
discussion.
## Setting Expectations {#ExpectCall}
See [`EXPECT_CALL`](reference/mocking.md#EXPECT_CALL) in the Mocking Reference.
## Matchers {#MatcherList}
See the [Matchers Reference](reference/matchers.md).
## Actions {#ActionList}
See the [Actions Reference](reference/actions.md).
## Cardinalities {#CardinalityList}
See the [`Times` clause](reference/mocking.md#EXPECT_CALL.Times) of
`EXPECT_CALL` in the Mocking Reference.
## Expectation Order
By default, expectations can be matched in *any* order. If some or all
expectations must be matched in a given order, you can use the
[`After` clause](reference/mocking.md#EXPECT_CALL.After) or
[`InSequence` clause](reference/mocking.md#EXPECT_CALL.InSequence) of
`EXPECT_CALL`, or use an [`InSequence` object](reference/mocking.md#InSequence).
## 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);
```
Do not set new expectations after verifying and clearing a mock after its use.
Setting expectations after code that exercises the mock has undefined behavior.
See [Using Mocks in Tests](gmock_for_dummies.md#using-mocks-in-tests) for more
information.
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](gmock_cook_book.md#UsingCheckPoints) for one application of
it.
## Flags
| Flag | Description |
| :----------------------------- | :---------------------------------------- |
| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

third_party/googletest/docs/pkgconfig.md 0 → 100644
## 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
find_package(PkgConfig)
pkg_search_module(GTEST REQUIRED gtest_main)
add_executable(testapp)
target_sources(testapp PRIVATE samples/sample3_unittest.cc)
target_link_libraries(testapp PRIVATE ${GTEST_LDFLAGS})
target_compile_options(testapp PRIVATE ${GTEST_CFLAGS})
enable_testing()
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`.
### 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`.
### Using pkg-config in a cross-compilation setting
Pkg-config can be used in a cross-compilation setting too. To do this, let's
assume the final prefix of the cross-compiled installation will be `/usr`, and
your sysroot is `/home/MYUSER/sysroot`. Configure and install GTest using
```
mkdir build && cmake -DCMAKE_INSTALL_PREFIX=/usr ..
```
Install into the sysroot using `DESTDIR`:
```
make -j install DESTDIR=/home/MYUSER/sysroot
```
Before we continue, it is recommended to **always** define the following two
variables for pkg-config in a cross-compilation setting:
```
export PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=yes
export PKG_CONFIG_ALLOW_SYSTEM_LIBS=yes
```
otherwise `pkg-config` will filter `-I` and `-L` flags against standard prefixes
such as `/usr` (see https://bugs.freedesktop.org/show_bug.cgi?id=28264#c3 for
reasons why this stripping needs to occur usually).
If you look at the generated pkg-config file, it will look something like
```
libdir=/usr/lib64
includedir=/usr/include
Name: gtest
Description: GoogleTest (without main() function)
Version: 1.11.0
URL: https://github.com/google/googletest
Libs: -L${libdir} -lgtest -lpthread
Cflags: -I${includedir} -DGTEST_HAS_PTHREAD=1 -lpthread
```
Notice that the sysroot is not included in `libdir` and `includedir`! If you try
to run `pkg-config` with the correct
`PKG_CONFIG_LIBDIR=/home/MYUSER/sysroot/usr/lib64/pkgconfig` against this `.pc`
file, you will get
```
$ pkg-config --cflags gtest
-DGTEST_HAS_PTHREAD=1 -lpthread -I/usr/include
$ pkg-config --libs gtest
-L/usr/lib64 -lgtest -lpthread
```
which is obviously wrong and points to the `CBUILD` and not `CHOST` root. In
order to use this in a cross-compilation setting, we need to tell pkg-config to
inject the actual sysroot into `-I` and `-L` variables. Let us now tell
pkg-config about the actual sysroot
```
export PKG_CONFIG_DIR=
export PKG_CONFIG_SYSROOT_DIR=/home/MYUSER/sysroot
export PKG_CONFIG_LIBDIR=${PKG_CONFIG_SYSROOT_DIR}/usr/lib64/pkgconfig
```
and running `pkg-config` again we get
```
$ pkg-config --cflags gtest
-DGTEST_HAS_PTHREAD=1 -lpthread -I/home/MYUSER/sysroot/usr/include
$ pkg-config --libs gtest
-L/home/MYUSER/sysroot/usr/lib64 -lgtest -lpthread
```
which contains the correct sysroot now. For a more comprehensive guide to also
including `${CHOST}` in build system calls, see the excellent tutorial by Diego
Elio Pettenò: <https://autotools.io/pkgconfig/cross-compiling.html>

# Quickstart: Building with Bazel
This tutorial aims to get you up and running with GoogleTest using the Bazel
build system. If you're using GoogleTest for the first time or need a refresher,
we recommend this tutorial as a starting point.
## Prerequisites
To complete this tutorial, you'll need:
* A compatible operating system (e.g. Linux, macOS, Windows).
* A compatible C++ compiler that supports at least C++14.
* [Bazel](https://bazel.build/), the preferred build system used by the
GoogleTest team.
See [Supported Platforms](platforms.md) for more information about platforms
compatible with GoogleTest.
If you don't already have Bazel installed, see the
[Bazel installation guide](https://bazel.build/install).
{: .callout .note} Note: The terminal commands in this tutorial show a Unix
shell prompt, but the commands work on the Windows command line as well.
## Set up a Bazel workspace
A
[Bazel workspace](https://docs.bazel.build/versions/main/build-ref.html#workspace)
is a directory on your filesystem that you use to manage source files for the
software you want to build. Each workspace directory has a text file named
`WORKSPACE` which may be empty, or may contain references to external
dependencies required to build the outputs.
First, create a directory for your workspace:
```
$ mkdir my_workspace && cd my_workspace
```
Next, you’ll create the `WORKSPACE` file to specify dependencies. A common and
recommended way to depend on GoogleTest is to use a
[Bazel external dependency](https://docs.bazel.build/versions/main/external.html)
via the
[`http_archive` rule](https://docs.bazel.build/versions/main/repo/http.html#http_archive).
To do this, in the root directory of your workspace (`my_workspace/`), create a
file named `WORKSPACE` with the following contents:
```
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
name = "com_google_googletest",
urls = ["https://github.com/google/googletest/archive/5ab508a01f9eb089207ee87fd547d290da39d015.zip"],
strip_prefix = "googletest-5ab508a01f9eb089207ee87fd547d290da39d015",
)
```
The above configuration declares a dependency on GoogleTest which is downloaded
as a ZIP archive from GitHub. In the above example,
`5ab508a01f9eb089207ee87fd547d290da39d015` is the Git commit hash of the
GoogleTest version to use; we recommend updating the hash often to point to the
latest version. Use a recent hash on the `main` branch.
Now you're ready to build C++ code that uses GoogleTest.
## Create and run a binary
With your Bazel workspace set up, you can now use GoogleTest code within your
own project.
As an example, create a file named `hello_test.cc` in your `my_workspace`
directory with the following contents:
```cpp
#include <gtest/gtest.h>
// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
// Expect two strings not to be equal.
EXPECT_STRNE("hello", "world");
// Expect equality.
EXPECT_EQ(7 * 6, 42);
}
```
GoogleTest provides [assertions](primer.md#assertions) that you use to test the
behavior of your code. The above sample includes the main GoogleTest header file
and demonstrates some basic assertions.
To build the code, create a file named `BUILD` in the same directory with the
following contents:
```
cc_test(
name = "hello_test",
size = "small",
srcs = ["hello_test.cc"],
deps = ["@com_google_googletest//:gtest_main"],
)
```
This `cc_test` rule declares the C++ test binary you want to build, and links to
GoogleTest (`//:gtest_main`) using the prefix you specified in the `WORKSPACE`
file (`@com_google_googletest`). For more information about Bazel `BUILD` files,
see the
[Bazel C++ Tutorial](https://docs.bazel.build/versions/main/tutorial/cpp.html).
{: .callout .note}
NOTE: In the example below, we assume Clang or GCC and set `--cxxopt=-std=c++14`
to ensure that GoogleTest is compiled as C++14 instead of the compiler's default
setting (which could be C++11). For MSVC, the equivalent would be
`--cxxopt=/std:c++14`. See [Supported Platforms](platforms.md) for more details
on supported language versions.
Now you can build and run your test:
<pre>
<strong>my_workspace$ bazel test --cxxopt=-std=c++14 --test_output=all //:hello_test</strong>
INFO: Analyzed target //:hello_test (26 packages loaded, 362 targets configured).

This tutorial aims to get you up and running with GoogleTest using CMake. If
you're using GoogleTest for the first time or need a refresher, we recommend
this tutorial as a starting point. If your project uses Bazel, see the
[Quickstart for Bazel](quickstart-bazel.md) instead.
## Prerequisites
To complete this tutorial, you'll need:
* A compatible operating system (e.g. Linux, macOS, Windows).
* A compatible C++ compiler that supports at least C++14.
* [CMake](https://cmake.org/) and a compatible build tool for building the
project.
* Compatible build tools include
[Make](https://www.gnu.org/software/make/),
[Ninja](https://ninja-build.org/), and others - see
[CMake Generators](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html)
for more information.
See [Supported Platforms](platforms.md) for more information about platforms
compatible with GoogleTest.
If you don't already have CMake installed, see the
[CMake installation guide](https://cmake.org/install).
{: .callout .note}
Note: The terminal commands in this tutorial show a Unix shell prompt, but the
commands work on the Windows command line as well.
## Set up a project
CMake uses a file named `CMakeLists.txt` to configure the build system for a
project. You'll use this file to set up your project and declare a dependency on
GoogleTest.
First, create a directory for your project:
```
$ mkdir my_project && cd my_project
```
Next, you'll create the `CMakeLists.txt` file and declare a dependency on
GoogleTest. There are many ways to express dependencies in the CMake ecosystem;
in this quickstart, you'll use the
[`FetchContent` CMake module](https://cmake.org/cmake/help/latest/module/FetchContent.html).
To do this, in your project directory (`my_project`), create a file named
`CMakeLists.txt` with the following contents:
```cmake
cmake_minimum_required(VERSION 3.14)
project(my_project)
# GoogleTest requires at least C++14
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
include(FetchContent)
FetchContent_Declare(
googletest
URL https://github.com/google/googletest/archive/03597a01ee50ed33e9dfd640b249b4be3799d395.zip
)
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
```
The above configuration declares a dependency on GoogleTest which is downloaded
from GitHub. In the above example, `03597a01ee50ed33e9dfd640b249b4be3799d395` is
the Git commit hash of the GoogleTest version to use; we recommend updating the
hash often to point to the latest version.
For more information about how to create `CMakeLists.txt` files, see the
[CMake Tutorial](https://cmake.org/cmake/help/latest/guide/tutorial/index.html).
## Create and run a binary
With GoogleTest declared as a dependency, you can use GoogleTest code within
your own project.
As an example, create a file named `hello_test.cc` in your `my_project`
directory with the following contents:
```cpp
#include <gtest/gtest.h>
// Demonstrate some basic assertions.
TEST(HelloTest, BasicAssertions) {
// Expect two strings not to be equal.
EXPECT_STRNE("hello", "world");
// Expect equality.
EXPECT_EQ(7 * 6, 42);
}
```
GoogleTest provides [assertions](primer.md#assertions) that you use to test the
behavior of your code. The above sample includes the main GoogleTest header file
and demonstrates some basic assertions.
To build the code, add the following to the end of your `CMakeLists.txt` file:
```cmake
enable_testing()
add_executable(
hello_test
hello_test.cc
)
target_link_libraries(
hello_test
GTest::gtest_main
)
include(GoogleTest)
gtest_discover_tests(hello_test)
```
The above configuration enables testing in CMake, declares the C++ test binary
you want to build (`hello_test`), and links it to GoogleTest (`gtest_main`). The
last two lines enable CMake's test runner to discover the tests included in the
binary, using the
[`GoogleTest` CMake module](https://cmake.org/cmake/help/git-stage/module/GoogleTest.html).
Now you can build and run your test:
<pre>
<strong>my_project$ cmake -S . -B build</strong>
-- The C compiler identification is GNU 10.2.1
-- The CXX compiler identification is GNU 10.2.1
...
-- Build files have been written to: .../my_project/build
<strong>my_project$ cmake --build build</strong>
Scanning dependencies of target gtest
...
[100%] Built target gmock_main
<strong>my_project$ cd build && ctest</strong>
Test project .../my_project/build
Start 1: HelloTest.BasicAssertions
1/1 Test #1: HelloTest.BasicAssertions ........ Passed 0.00 sec
100% tests passed, 0 tests failed out of 1
Total Test time (real) = 0.01 sec
</pre>
Congratulations! You've successfully built and run a test binary using
GoogleTest.
## Next steps
* [Check out the Primer](primer.md) to start learning how to write simple
tests.
* [See the code samples](samples.md) for more examples showing how to use a
variety of GoogleTest features.

# Actions Reference
[**Actions**](../gmock_for_dummies.md#actions-what-should-it-do) specify what a
mock function should do when invoked. This page lists the built-in actions
provided by GoogleTest. All actions are defined in the `::testing` namespace.
## Returning a Value
| Action | Description |
| :-------------------------------- | :-------------------------------------------- |
| `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. |
| `ReturnRoundRobin({a1, ..., ak})` | Each call will return the next `ai` in the list, starting at the beginning when the end of the list is reached. |
## Side Effects
| Action | Description |
| :--------------------------------- | :-------------------------------------- |
| `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.
| Action | Description |
| :---------------------------------- | :------------------------------------- |
| `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. |
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 `std::ref()`. For example,
```cpp
using ::testing::InvokeArgument;
...
InvokeArgument<2>(5, string("Hi"), std::ref(foo))
```
calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by
value, and `foo` by reference.
## Default Action
| Action | Description |
| :------------ | :----------------------------------------------------- |
| `DoDefault()` | Do the default action (specified by `ON_CALL()` or the built-in one). |
{: .callout .note}
**Note:** due to technical reasons, `DoDefault()` cannot be used inside a
composite action - trying to do so will result in a run-time error.
## Composite Actions
| Action | Description |
| :----------------------------- | :------------------------------------------ |
| `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 and will receive a readonly view of the arguments. |
| `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. |
## Defining Actions
| Macro | Description |
| :--------------------------------- | :-------------------------------------- |
| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
The `ACTION*` macros cannot be used inside a function or class.

* Sample #4 teaches you how to use googletest and `googletest.h` together to
get the best of both libraries.
* Sample #5 puts shared testing logic in a base test fixture, and reuses it in
derived fixtures.
* Sample #6 demonstrates type-parameterized tests.
* Sample #7 teaches the basics of value-parameterized tests.

# 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](https://easymock.org/)
* [Hamcrest](https://code.google.com/p/hamcrest/)
It is 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.
- Is easy to learn and use.
Details and examples can be found here:
* [gMock for Dummies](https://google.github.io/googletest/gmock_for_dummies.html)
* [Legacy gMock FAQ](https://google.github.io/googletest/gmock_faq.html)
* [gMock Cookbook](https://google.github.io/googletest/gmock_cook_book.html)
* [gMock Cheat Sheet](https://google.github.io/googletest/gmock_cheat_sheet.html)
GoogleMock is a part of
[GoogleTest C++ testing framework](https://github.com/google/googletest/) and a
subject to the same requirements.
