Mutation testing with Mutant

I just released a new version of Mutant, a mutation tester for Rubinius, and blogged about it.


very awesome, i gotta ask though, when evaluating the rspec suite does it allow you to specify a ruby interpreter to use or does it evaluate on Rubinius? (sadly i’m stuck on an inherited 1.8.x project and not likely to upgrade for a while)

It has to evaluate it in Rubinius, since it parses the code, mutates the parse tree, and then reevaluates it. Rubinius does work in 1.8 mode too (in fact it’s the default mode) – it’s likely that your project just works on it. I encourage you to try :)
