Hi, It probably should have happened ages ago [1] but now its there via https://issues.jboss.org/browse/JBIDE-19110 Mockito is now available in master of jboss tools core target platform. Meaning you can now use mocks in your tests without custom inclusion/setup. We do have other mocking frameworks in play, but please consider using mockito instead of something custom going forward. Mind you that we are using a fork of Mockito to work around limit of what happens when you have multiple versions of a binary loaded in the IDE - but if you don't have that you shouldn't care ;) You can read more about mockito at http://mockito.org/ or google "eclipse mockito" to have fun with the subtleties osgi gives you ;) [1] I'll explain why mockito with osgi sucks over a beer :) /max http://about.me/maxandersen
