OSS Builds Status:

Build Status Build status


Release 1.10.x

Release 1.10.x is now available.

Coming Soon

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 for questions, discussions, and development.

Getting started:

The information for Google Test is available in the Google Test Primer documentation.

Google Mock is an extension to Google Test for writing and using C++ mock classes. See the separate Google Mock documentation.

More detailed documentation for googletest is in its interior googletest/ 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.


Google test has been used on a variety of platforms:

  • Linux
  • Mac OS X
  • Windows
  • Cygwin
  • MinGW
  • Windows Mobile
  • Symbian
  • PlatformIO

Who Is Using Google Test?

In addition to many internal projects at Google, Google Test 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.

Google Test UI is 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 Google Test 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 Google Tests in a tree view, and run/debug your tests.

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

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


Google Test is designed to have fairly minimal requirements to build and use with your projects, but there are some. If you notice any problems on your platform, please notify Patches for fixing them are welcome!

Build Requirements

These are the base requirements to build and use Google Test from a source package:

  • Bazel or CMake. NOTE: Bazel is the build system that googletest is using internally and tests against. CMake is community-supported.

  • a C++11-standard-compliant compiler
