Pit RV
Research focussed mutation operators for pitest.
Note, these operators were built into pitest until release 1.7.5. From 1.7.5 onwards, this plugin is required if we wish to use the rv operators.
Usage
To use the plugin it must be placed on the classpath of the pitest tool (not on the classpath of the project being mutated).
