[Zope-dev] More unit test questions

OK, I got test.py running. But if I run bin/python test.py Products it will happily try to run the tests in all products. But if I type bin/python test.py Products/Productname It will find no tests at all. bin/python test.py Products/Productname/tests is no better. BUT! If I type bin/python test.py lib/python/Products/ZCTextIndex it does find the tests for ZCTextIndex. In short: Heuh? What are the difference that makes it impossible to test just one products unit test if it's located in Products instead of lib/python/Products. Or is there a difference in how the CMF tests are written? Anybody know?
