* The ``mox`` mocking framework via ``self.mox``.
* A set of request context data via ``self.context``.
* A ``RequestFactory`` class which supports Django's ``contrib.messages``
framework via ``self.factory``.
* A ready-to-go request object via ``self.request``.
* The ability to override specific time data controls for easier testing.
* Several handy additional assertion methods.
