heckle in ruby is inspired by jester for java. I quote: Heckle is a mutation tester. It modifies your code and runs your tests to make sure they fail. The idea is that if code can be changed and your tests don't notice, either that code isn't being covered or it doesn't do anything. from http://glu.ttono.us/articles/2006/12/19/tormenting-your-tests-with-heckle
Is there anything similar for python?? -- http://mail.python.org/mailman/listinfo/python-list
