The problem is that in SiteDefinition.py, line 205, 
Zope.App.Traversing.traverse() is being called, and the test hasn't set 
up an Adapters service, and hasn't registered an IPhysicallyLocatable 
adapter with that service. This is required in order for the call to 
traverse() to work.

Also, if the test is setting up things to do with global adapter 
registries, the test class needs to derive from PlacelessSetup.
