Heckle Description

Open source mutation tester that will modify your code and run 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.It‘s like hiring a white-hat hacker to try to break into your server and making sure you detect it. You will learn the most by trying to break things and watching the outcome in an act of Ruby unit test sadism. Here are some key features of "Heckle": · Mutates booleans, numbers, strings, symbols, ranges, regexes and branches (if, while, unless, until) · Able to mutate entire classes, or individual methods · Can not yet mutate class methods Requirements: · ParseTree 1.6.1 or later What's New in This Release: · Added autotest/heckle plugin · Skipping testing on 1.9
