I haven't seen anyone talk about mutation testing as a strategy for avoiding regressions on legacy code without perfect test coverage.

@jbackus3 Seeing every place the test suite allows old code to change is powerful. Each mutation = potential bug you wouldn't catch -
@jbackus3 maybe more strict with critical pieces, less so with others - just like most test coverage i suppose? -
@mifreewil Yea does make you be more thorough with tests but this is important with dynamic languages. Definitely check out the blog post.
