This is what I was seeing with the original test_messageboard.py (comments 
at the end) ...

I thought it made sense - looking at 
zope/app/container/tests/test_icontainer.py the BaseTestIContainer class 
does call those getUnknownKey and getBadKeyTypes methods, but since the 
sample code from the wiki code doesn't define them I can see how it would 
fail.

I figured the easier alternative was to subclass the Test from 
test_icontainer.py, which gets you the missing methods, along with 
makeTestData.

test_message.py came up with exactly the same errors IIRC.
