Update of /cvs-repository/Zope2/lib/python/ZODB/tests
In directory korak.digicool.com:/tmp/cvs-serv31318

Added Files:
	IteratorStorage.py 
Log Message:
A bunch of unittests for the iterator() method and interface of the
storage API.



--- Added File IteratorStorage.py in package Zope2/lib/python/ZODB ---
# Run tests against the iterator() interface for storages.  Any storage that
# supports the iterator() method should be able to pass all these tests.
