[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].

It employs a 'test binary', a compiled program responsible for executing tests and analyzing their results, to evaluate software functionality.
