Mutmut is a mutation testing system for Python, with a strong focus on ease of use. If you don't know what mutation testing is try starting with this article.

Some highlight features: * Found mutants can be applied on disk with a simple command making it very easy to work with the results * Remembers work that has been done, so you can work incrementally * Supports all test runners (because mutmut only needs an exit code from the test command) * Can use coverage data to only do mutation testing on covered lines * Battle tested on real libraries by multiple companies
