Hi,

Using VerveineJ, the stub classes realted to unit tests (TestCase, TestSuit and Test classes)  are not imported
also their namesapce junit.framework
These classes are imported using inFamix.

junit.framework.TestCase class is particularly important in order to automatically detect unit test classes: TestCase subclassHierarchy.
If this class is not available in the moose model then the only way to automatically detect unit test classes is by detecting the classes that their names are postfixed by 'Tests': 
mooseModel allClasses select: [:c| '*Tests' match: c name]
such a way can provide us with wrong results!

Cheers,
Hani

P.S.: use-case JFreechart project: http://sourceforge.net/projects/jfreechart/files/latest/download
which includes about 380 test classes (classes inherit from TestCase)
