Google Test
C++ testing framework by Google
From Wikipedia, the free encyclopedia
Google Test, often written as GoogleTest and referred to as gtest, is a specialized 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.[2] Google Test is free and open-source software with a BSD 3-clause license.[3]

Google Test can be compiled for a diverse range of 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 adaptability facilitates executing unit tests on both C and C++ codebases, with minimal alterations needed in the source code.[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 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 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#.[7] A Visual Studio extension, Google Test Adapter, complements its functions within the Visual Studio environment.[8]
