title: testing custom devise and/or warden strategy with rspec
body: <p>I see plenty that lead to custom authorization strategies for devise and warden, but what I'm sepcifically after is testing these solutions with rspec.  Similar to this question: <a href="https://stackoverflow.com/questions/4141094/filtering-users-who-are-able-to-sign-in-with-devise">Filtering users who are able to sign in with Devise</a></p>
  
  <p>What can I do to test this sort of implementation.  Rails 3.1.1, Devise (most current), etc.</p>
