While looking at http://code.google.com/p/junit-idea-plugin/ ...
... we were quite interested in the RefactoringListenerManager.getInstance().addListenerProvider( .. )
However that as a project was last updated in 2007, and Maia <cough/> Intellij 9.0 uses its own Junit 4 plugin, nor does it recognize the API in that GoogleCode project.
Looking at the built-in one, it seems it uses an "extension points" concept. The IDEAJUniListener extension point does not implement an abstraction (that's odd !?) and we can't find sibling extension points.
Is there a list of extension points anywhere ?
