Build Status Dependency Status Code Climate

Mutant is a mutation testing tool for ruby that aims to be better than existing mutation testers. 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.

Mutant does currently only support 1.9 mode under rubinius or mri.

Installation

Install the gem mutant via your preferred method.

Examples

cd your_lib
# Run mutant on virtus (that uses the dm-2 style spec layout)
mutant -I lib -r virtus --rspec-dm2 ::Virtus

Credits

  • A gist from dkubb showing ideas.
  • Older abandoned mutant. For motivating me doing this one.
  • heckle. For getting me into mutation testing.

Contributing

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with Rakefile or version (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
