  # In addition to the stock matchers from rspec-expectations, request
  # specs add these matchers, which delegate to rails' assertions:
  #
  #   response.should render_template(*args)
  #   => delegates to assert_template(*args)
  #
  #   response.should redirect_to(destination)
  #   => delegates to assert_redirected_to(destination)
