You're using Mockito and Groovy. Maybe you've noticed that, when you try to mock a Groovy class from a Groovy test, it fails horribly. Now it won't!
Specifically, this library provides a workaround for Mockito Issue 303: http://code.google.com/p/mockito/issues/detail?id=303
Download the jar from the "releases" tab here in github, or use the Maven central repository. Enjoy!
Moss Collum and Laura Dean of Cyrus Innovation wrote the original version. Jostein Gogstad contributed the code to support verification and argument matchers.
