Heckle: Nifty Ruby Code Mutation Tester

Posted on February 14, 2007

I love the idea behind Heckle:

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.

To install:

sudo gem install heckle

Maybe I’ll spend today finishing writing those tests….
