Mutation testing has been proven to be a reliable method to estimate the quality of a test suite. Most of current mutation tools require the architecture of their target system to be in a certain way in order to apply the technique; thus making it impossible to use them in complex build environments. LittleDarwin is a mutation testing tool designed primarily with the premise of easy deployment in complex systems; in order to provide mutation testing where other tools fail.
