PIT is a fast bytecode based mutation testing system for Java that makes it possible to test the effectiveness of your unit tests. You can think of mutation testing as either as an automated test of your tests or as a much more in-depth form of code coverage. Unlike traditional line and branch coverage tools, PIT does not just confirm that your tests execute your code, it confirms that your tests are actually able to detect faults in it.

Changes:
This release integrates pit with version control, allowing selective mutation based on the status of source files within the configured version control system. Also included is support for parameterised spock tests, junit param tests, and numerous other small fixes and improvements
