- ``repoze.bfg.testing.DummyRequest`` will now contain ``params``,

  ``GET``, and ``POST`` attributes that are instances of the class
  ``FauxMultiDict``.  A FauxMultiDict differs from a "plain"
  dictionary inasmuch as it has a ``getall`` method.  ``getall`` is an
  interface exposed by the MultiDict implementation used by WebOb for
  ``params``, ``GET``, and ``POST``.
