[Tres Seaver]

Update of /cvs-repository/Products/CMFCore/tests/base

Modified Files:
      Tag: CMF-1_5-branch
	testcase.py 
Log Message:


 - Added testing framework to suppress / examine output from warnings
   module and from zLOG (cleaner than just 'filterwarnings', which was
   leaving nasty side effects).
