 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.

Actually, it wasn't that bad:

from Products.Five import zcml

class Tests(unittest.TestCase):

 def setUp(self):
 cleanup.cleanUp()
 zcml._initialized = False
 zcml.load_site()

 def tearDown(self):
 cleanup.cleanUp()

cheers,

Chris

 When trying to test a template in a unit test, I get the following 
 exception:

 LocationError: ('No traversable adapter found', {'content': MyObject,

 Now, the same template works just fine when used for real, so I figure 
 some standard traversal adapter hasn't been registered when the test runs.
