Tiny Test System is a C++20 open-source Unit Test library designed following the ideas of libraries like CATCH or LEST.
In addition to classical TDD features, its main goal is to provide:
- Test over data sets
- Support for template test cases generation
- IEEE precision-related tests: ULP, absolute and relative error
- Customization points for 3rd party types
- Streamlined behavior for interaction with post-processing scripts
TTS is thus suitable for numerical-heavy testing.
- g++ 10.3 and superior
- clang 12 and superior
- Visual Studio 17 2022 v19.30.30709.0
- clang-CL 15.0.1 or superior
- emscripten 3.1.14
