GoogleTest

Summary

GoogleTest is Google’s C++ framework for testing and mocking. Based on the xUnit architecture, it supports many kinds of C++ tests rather than only unit tests, and discovers and runs tests without manual registration. Its assertions cover equality, inequality, exceptions and other conditions, with support for custom assertions. The framework offers fatal and non-fatal failure handling, death tests, and value- or type-parameterized cases. Developers can run selected tests, set their order or run them in parallel. GoogleTest provides quickstarts for Bazel and CMake, plus pkg-config files for compiling and linking GoogleTest and GoogleMock. Its guide includes introductory and advanced material, mocking guidance, FAQs, references, examples and community documentation. The project follows Google’s Foundational C++ Support Policy and publishes supported compiler, platform and build-tool versions. The 1.18.x branch requires at least C++17. GoogleTest is free and uses the BSD-3-Clause license, which permits redistribution subject to its terms.

Who it is for

It suits C++ developers who need testing and mocking across different kinds of tests. Teams using Bazel or CMake can refer to its quickstarts.
