[mevenide-user] debugging JUnit tests

I'm using the current version of mavenide with nb6 m10 (sorry I can't
come up with the exact version of mavenide because I'm using the
autoupdate feature and a don't see version info).
 
If I create a Junit 4 style unit test - how do I debug it?
 
Run File and Debug File are available on the context menu but
breakpoints have no effect (the ide sees them but does not stop).
 
Should there be a a Debug Test option?
 
Thanks
