Update of /cvs-repository/Zope3/lib/python/Persistence/tests
In directory cvs.zope.org:/tmp/cvs-serv11228/Persistence/tests
Modified Files:
testModule.py
Log Message:
Refactor persistent modules.
This is a saner interface that decouples module management (creation /
updation) from importing. There is a base importer, although it is
not clear how useful it is. The test importer may end up being more
useful for ZODB applications other than Zope, although there are some
bootstrapping issues.
Disable the reload() tests. They're not working and we're not
interested in finding out why right now.
