In my current project we decided to use JBoss Drools 6, mainly for mapping data. It turned out to come in quite handy. However, when I tried to unit test my rules I was astonished how clumsy and cumbersome that was. Therefore I wrote a little library containing a JUnit-Runner that hides the needed boiler plate code and just lets you focus on the important thing: testing the rules.
