When running a simple test with three scenarios, all of which are successful, the output from IntelliJ IDEA is messed up and looks like the test execution was not a success. See http://i40.tinypic.com/sx2h5g.png for a screenshot.
The problems are:
This happens using IntelliJ UE 10.5.2 on OS X Lion (10.7.2). I get a feeling that exactly which test is labelled as successful is a bit random, even though subsequent executions of the same set of tests seems to lead to identical results.
I think this might be related to this bug: https://github.com/KentBeck/junit/pull/184
Improved JUnit runner. Closes #107,#211,#216
