That groks the whole sample package, right? I do not want that, since 
that can have all kinds of effects. What I am looking for is the very 
minimal thing that allows me to instantiate a view so I can call methods 
on it. Currently I use this:

     def setUp(self):
         # grok makes unit testing extremely painful
         View.__view_name__ = "iew"
         View.module_info=Mock()
         View.module_info.package_dotted_name="euphorie.content.model.View"

     def tearDown(self):
         del View.__view_name__
         del View.module_info

     def testSomething(self):
         model=Model()
         view=View(model, None)
         # Do the tests here


which works, but is not quite optimal
