[Zodb-checkins] CVS: Zope/lib/python/BTrees/tests - testBTrees.py:1.44

[Tim Peters]

Update of /cvs-repository/Zope/lib/python/BTrees/tests
In directory cvs.zope.org:/tmp/cvs-serv8446/tests

Modified Files:
	testBTrees.py 
Log Message:
BTrees and TreeSets have a new ._check() method.  This does a thorough job
of verifying that BTree invariants are satisfied, raising AssertionError
if they're not.  Nothing calls this method by magic; it's for debugging.
