[Zope-Checkins] CVS: StandaloneZODB/ZODB/tests - BasicStorage.py:1.13

[Barry Warsaw]

Update of /cvs-repository/StandaloneZODB/ZODB/tests
In directory cvs.zope.org:/tmp/cvs-serv29691

Modified Files:
	BasicStorage.py 
Log Message:
checkSerialIsNoneForInitialRevision(): New test that checks for
acceptability of serials=None for the object-creation store() call.
Note that _dostore() itself never exercises this condition because it
coerces its own serial argument to ZERO (a.k.a. '\0'*8) when None is
passed in.
