Heckle version 1.1.0 has been released!

Unit Testing Sadism.

From http://glu.ttono.us/articles/2006/12/19/tormenting-y...
with-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.

It’s a little weird, I know, but I like to think about it as pen-
testing. It’s like hiring a white-hat hacker to try to break into
your server and making sure you detect it. You learn the most by
trying to break things and watching the outcome.

Anyway, Heckle was inspired by Jester, and Ryan Davis wrote a proof
of concept at RubyConf. As he notes, I went a little nuts and much of
the current implementation I rewrote that night or on the plane home.
