  # @example
  #   Warden.test_mode!

  # This will provide a number of methods.
  # Warden.on_next_request(&blk) - captures a block which is yielded the warden proxy on the next request
  # Warden.test_reset! - removes any captured blocks that would have been executed on the next request
  #
  # Warden.test_reset! should be called in after blocks for rspec, or teardown methods for Test::Unit
