[Zope-Checkins] CVS: Releases/Zope/utilities - testrunner.py:1.25

[Guido van Rossum]

Update of /cvs-repository/Releases/Zope/utilities
In directory cvs.zope.org:/tmp/cvs-serv26204

Modified Files:
	testrunner.py 
Log Message:
Add "remove_stale_bytecode()".  This removes .pyc and .pyo files that
don't have a corresponding .py file, to prevent tests that import
deleted modules from running using the stale bytecode files.  This has
bitten enough people enough times that it's time it became a standard
part of every test suite runner.  (Zope3 already has it.)

Somebody merge this into the Zope2 trunk please.
