The run configuration for a test class can create another cause (and solution) for this problem.

If you go to Run (or Debug) Configurations (using cmd-3 or clicking on the small dropdown buttons in the toolbar) you can see a configuration created for every test class you've worked with. I found that one of my classes that wouldn't launch had a run configuration where the Test Method field had somehow gotten inadvertently populated. I had to clear that to get it to work. When cleared it shows (all methods) in light text.

I'll add that strangely — maybe there was something else going on — it also seemed not to work for me until I fixed the "Name" field as well so that it included only the class name like the other JUnit run configurations.
