[Zope-Checkins] CVS: ZODB3/persistent/tests - testPersistent.py:1.2.10.1

[Fred L. Drake, Jr.]

Update of /cvs-repository/ZODB3/persistent/tests
In directory cvs.zope.org:/tmp/cvs-serv21094

Modified Files:
      Tag: zope3-zodb3-devel-branch
	testPersistent.py 
Log Message:
added tests for:
- add _p_invalidate() method to invalidate an object unconditionally;
  this is equivalent to _p_deactivate(force=True) from ZODB 4
- add _p_state as read-only access to the current state; no weird
  interpretation based on _p_changed needed
