Yup. I bet you just need to do
zope.component.provideAdapter(zope.traversing.adapters.DefaultTraversable).
The Zope 3 page template engine will use ITraversable adapters to
traverse just about anything. So, basically, wherever you're employing a
page template in CMF tests, you'll want this adapter.
