Ruby code mutator other than heckle?

I am working with ruby ​​1.8, rails 3.1 and rspec 2.7

I am trying to do very good tests, I want to try one of these code mutation tools. I just found Heckle, but it seems to be very outdated, and it's hard for me to work with it. Is there any other mutation tool for Ruby? or is there any other way to get some automatic feedback on the quality of the tests? (excluding coverage)

I rewrote mutant from scratch.

Instructions for use can be found in the Readme on Github. Mutant targets MRI and RBX at 2.0 / 2.1 / 2.2. Currently, he can only kill mutations with rspec3, but other killers are possible.

Check out the mutant . This is a rewrite of a check built on top of Rubinius.
