Mutation testing is a technique for systematically mutating source code in order to validate test suites. It makes small changes to a program's source code and then runs a test suite; if the test suite ever succeeds on mutated code then a flag is raised. I'll begin this presentation with a description of the theory behind mutation testing, and then I'll move into an analysis of Cosmic Ray, a tool for mutation testing in Python. While some of the details of this presentation will necessarily be Python­ specific, the concepts and lessons are broadly applicable and should be interesting to anyone involved in producing software.
