Currently, the default javadoc for a JUnit test method is defined in org/netbeans/modules/junit/Bundle.properties as:

TestCreator.variantMethods.JavaDoc.comment=Test of {0} method, of class {1}.

I prefer to have a slightly different javadoc for my test methods, but having the javadoc comment being stored in this resource bundle makes it difficult (if not impossible) to change how the comments are initially created, so I normally have to go through and edit them manually after they are created.

If the javadoc comments for test methods were part of the "Unit Tests" templates for JUnit, it would make editing and customizing the default javadoc much easier.
