For any Python users, there's a library that automates mutation testing by parsing the AST: https://github.com/EvanKepner/mutatest

And for property-based testing there's Hypothesis too: https://hypothesis.readthedocs.io/en/latest/

There's mutmut (I'm the maintainer), cosmic-ray and mutpy too. In fact those are the established players. I have never heard of mutate st before! I will have to try it.
