Ah, so I probably wasn't clear enough regarding the mock in my previous
comments, sorry. We use gmock for generating mocks and handling calls into
these. See http://code.google.com/p/googlemock/

The idea is that calls into the mock get caught and you can associate whatever
action should be performed on the call. You can also configure the return value.
Thus, you don't need the actual policy provider, but you can just instruct the
mock to return a suitable DictionaryValue upon calls to GetPolicyStatus().
