Export Test - Do Not Merge

Add static_asserts that verify that no class hierarchy contains more than one
of {NiceMock, NaggyMock, StrictMock}. This sort of nesting has always been
disallowed, but this CL adds a compile-time check to prevent it.

Release 1.10.x

Release 1.10.x is now available.

Coming Soon

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

The information for GoogleTest is available in the GoogleTest Primer documentation.

GoogleMock is an extension to GoogleTest for writing and using C++ mock classes. See the separate GoogleMock documentation.

More detailed documentation for googletest is in its interior googletest/README.md file.


  • An xUnit test framework.
  • Test discovery.
  • A rich set of assertions.
  • User-defined assertions.
  • Death tests.
  • Fatal and non-fatal failures.
  • Value-parameterized tests.
  • Type-parameterized tests.
  • Various options for running the tests.
  • XML test report generation.

Supported Platforms

GoogleTest requires a codebase and compiler compliant with the C++11 standard or newer.

The GoogleTest code is officially supported on the following platforms. Operating systems or tools not listed below are community-supported. For community-supported platforms, patches that do not complicate the code may be considered.

If you notice any problems on your platform, please file an issue on the GoogleTest GitHub Issue Tracker. Pull requests containing fixes are welcome!

Operating Systems

  • Linux
  • macOS
  • Windows


  • gcc 5.0+
  • clang 5.0+
  • MSVC 2015+

macOS users: Xcode 9.3+ provides clang 5.0+.

Build Systems

Note: Bazel is the build system used by the team internally and in tests. CMake is supported on a best-effort basis and by the community.

Who Is Using GoogleTest?

In addition to many internal projects at Google, GoogleTest is also used by the following notable projects:

Related Open Source Projects

GTest Runner is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.

GoogleTest UI is a test runner that runs your test binary, allows you to track its progress via a progress bar, and displays a list of test failures. Clicking on one shows failure text. Google Test UI is written in C#.

GTest TAP Listener is an event listener for GoogleTest that implements the TAP protocol for test result output. If your test runner understands TAP, you may find it useful.

gtest-parallel is a test runner that runs tests from your binary in parallel to provide significant speed-up.

GoogleTest Adapter is a VS Code extension allowing to view GoogleTest in a tree view, and run/debug your tests.

C++ TestMate is a VS Code extension allowing to view GoogleTest in a tree view, and run/debug your tests.

Cornichon is a small Gherkin DSL parser that generates stub code for GoogleTest.
