Java Mutation Testing

That's too bad that you had to stop using it.

I've never used one of these tools, but I knew they existed. Just today I was discussing "testing the tests" with a coworker. In my opinion, where I work we write lots of incomplete/illogical tests, sometimes bordering on cargo culting. Aside from code-coverage, which is flawed, we have no real measure of whether the tests we write are effective or not.

There is a tool to detect duplicate tests which many have found useful: http://ortask.com/testless/

For other kinds of test quality, try Mutator: http://ortask.com/mutator/

Thanks for the links!

I hate to sound negative, but something about that website seems dodgy. I'm unconvinced duplicate/overlapping tests -- while obviously undesirable -- have a direct correlation with code quality. Unfortunately, in order to read their "papers" where they elaborate on this, I have to register :/

I'd rather use something open source like pitest.

(Again, thanks for the links! I don't want to sound too negative)
