You're testing a facade already. A facade to a mock won't tell you whether it works against the real impl, you can just "fix" the mock to make any test pass. :-) Of course, if you're going to rerun these tests against the real implementation then that is fine. You probably want to design these tests for this reuse in mind? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133313#...
