DefaultTraversable, I think, and
from zope.app.testing import setup
setup.setUpTraversal()
Various other features need various other components, e.g. if your
template tries to use @@absolute_url, in addition to the above, you'll need
provideAdapter(zope.traversing.namespace.view,
adapts=(None, None),
provides=ITraversable,
name='view')
similarly for resources you do something like
ztapi.provideView(Interface, Interface, ITraversable, 'resource',
zope.traversing.namespace.resource)
ztapi.browserResource('style.css', ResourceStub)
and let's not even start talking about forms and widgets.
I'm not sure rendering page templates in unit tests is worth the pain.
