An experimental mutation testing framework for Ruby


Mutation testing asks "if your code is wrong, can your tests tell?" It's a simple but powerful idea that can find bugs in your code and improve your tests.

Mutiny is a modern implementation of mutation testing for Ruby. Mutiny is being developed as part of a research programme at the University of York.
