Excluding integration tests in pattern-drive JUnit run configuration

Hi,

In run configration of JUnit, if I use pattern, what syntax is expected there? For example this regex ^.*(?!LimitIT)$ is happily selecting *all* JUnit tests, however it should (if we assume, that java regexes are supported here) accept all but those ending with LimitIT.

So 1/ what is expected syntax here? 2/how does look like pattern which excludes all tests ending in IT suffix? Is it even possible?

thanks.
