Description

Mutant is a mutation testing tool for Ruby.

The idea is that if code can be changed and your tests do not notice, either that code isn't being covered or it does not have a speced side effect.

Mutant supports ruby >= 2.1, while support for JRuby is planned. It should also work under any Ruby engine that supports POSIX-fork(2) semantics.

Mutant uses a pure Ruby parser and an unparser to do its magic.

Mutant does not have really good "getting started" documentation currently so please refer to presentations and blog posts below.
