Google Test is based on the [xUnit](/source/XUnit) architecture, a systematic methodology for assessing software components.[2] Google Test is [free and open-source software](/source/Free_and_open-source_software) with a [BSD 3-clause license](/source/BSD_licenses#3-clause).[3] Google Test can be [compiled](/source/Compiler) for a diverse range of [computer](/source/Computer) [operating systems](/source/Operating_system) (OS), including those using the Portable Operating System Interface ([POSIX](/source/POSIX); e.g., [Linux](/source/Linux), [macOS](/source/MacOS)), a set of standard OS interfaces, and [Microsoft Windows](/source/Microsoft_Windows). This adaptability facilitates [executing](/source/Execution_(computing)) unit tests on both [C](/source/C_(programming_language)) and [C++](/source/C%2B%2B) [codebases](/source/Codebase), with minimal alterations needed in the [source code](/source/Source_code).[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] ## Projects using Google Test Besides being developed and used at Google, many other projects implement Google Test as well: - [Android Open Source Project](/source/Android_Open_Source_Project) operating system[4] - [Chromium](/source/Chromium_(web_browser)) projects (behind the [Chrome browser](/source/Google_Chrome) and [ChromeOS](/source/ChromeOS)) - [LLVM](/source/LLVM) compiler - [Protocol Buffers](/source/Protocol_Buffers) ([Google](/source/Google)'s data interchange format) - [OpenCV](/source/OpenCV) computer vision library - [Robot Operating System](/source/Robot_Operating_System)[5] - [GROMACS](/source/GROMACS) molecular dynamics simulation package[6] ## Related tools Google Test UI is a [software tool](/source/Software_tool) for testing computer programs, and serves as a test runner. It employs a 'test binary', a [compiled](/source/Compiler) program responsible for executing tests and analyzing their results, to evaluate software functions. It visually presents the testing progress via a [progress bar](/source/Progress_bar) and displays a list of identified issues or 'test failures'. The tool is primarily written in [C#](/source/C_Sharp_(programming_language)).[7] A [Visual Studio](/source/Visual_Studio) extension, Google Test Adapter, complements its functions within the Visual Studio environment.[8] ## See also - [Free and open-source software portal](https://en.wikipedia.org/wiki/Portal:Free_and_open-source_software) - [List of unit testing frameworks](/source/List_of_unit_testing_frameworks) - [CppUnit](/source/CppUnit) ## References 1. **[^](#cite_ref-1)** [Google Test v1.17.0 release notes](https://github.com/google/googletest/releases/tag/v1.17.0), retrieved 2025-10-14 1. **[^](#cite_ref-quick_intro_2-0)** [A quick introduction to the Google C++ Testing Framework](https://web.archive.org/web/20160316134644/http://www.ibm.com/developerworks/aix/library/au-googletestingframework.html), Arpan Sen, IBM DeveloperWorks, 2010-05-11, retrieved 2016-04-12 1. **[^](#cite_ref-3)** [Google Test's repository](https://github.com/google/googletest), retrieved 2016-04-12, cites [New BSD](http://opensource.org/licenses/BSD-3-Clause) as license.
