Google Test, often referred to as gtest, is a specialized library utilized to conduct unit testing in the C++ programming language. This library operates under the terms of the BSD 3-clause license.^[2] Google Test is based on the xUnit architecture, a systematic methodology for assessing software components.^[3]

Google Test can be compiled for a diverse range of computer systems, encompassing those employing POSIX, a set of standard operating system interfaces, as well as the Microsoft Windows platform. This adaptability facilitates the execution of unit tests on both C and C++ codebases, with minimal alterations required in the source code^{[citation needed]}.

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

• Android Open Source Project operating system^[4]
• Chromium projects (behind the Chrome browser and ChromeOS)
• LLVM compiler
• Protocol Buffers (Google's data interchange format)
• OpenCV computer vision library
• Robot Operating System^[5]
• Gromacs molecular dynamics simulation package^[6]

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 functionality. It visually presents the testing progress through a progress bar and displays a list of identified issues or 'test failures'. The tool is primarily written in C#.^[7] A Visual Studio extension, Google Test Adapter, complements its functionality within the Visual Studio environment.^[8]
