Originating from the PyPy project, this Python testing framework is utilized for writing diverse software tests, including unit, integration, end-to-end, and functional tests. It is known for features like parametrized testing, fixtures, and assert re-writing. The framework is designed to facilitate the creation of small, readable tests, and can also scale to support complex functional testing for applications and libraries. It is compatible with macOS, Windows, and POSIX platforms.
