Google Test, often written as GoogleTest and referred to as gtest, is a library used to conduct unit testing in the programming language C++. Google Test is based on the xUnit architecture, a systematic methodology for assessing software components. Google Test is free and open-source software with a BSD 3-clause license.

Google Test can be compiled for multiple computer operating systems (OS), including those using the Portable Operating System Interface (POSIX; e.g., Linux, macOS), a set of standard OS interfaces, and Microsoft Windows. This allows for the execution of unit tests on both C and C++ codebases with few alterations to the source code.[citation needed]

Projects using Google Test

Besides being developed and used at Google, many other projects implement Google Test as well:

Google Test UI is a software tool for testing computer programs, and serves as a test runner. It employs a 'test binary', a compiled program responsible for executing tests and analyzing their results, to evaluate software functions. It visually presents the testing progress via a progress bar and displays a list of identified issues or 'test failures'. The tool is primarily written in C#. A Visual Studio extension, Google Test Adapter, integrates the framework within the Visual Studio environment.
