I know I should just send this to the TestNG developers or something, but I'm unable to register on the javalobby hosted site, so I hope this works as well.
I tried to use the internal code coverage of IntelliJ 6.0. I'm using TestNG 5.1 + the lastest version of the plugin. When I record the code coverage, I see nothing. It seems like nothing is recorded. When using JUnit, the coverage information is displayed. Anyone encountered the same problem?
