TEST/UNIT:

assert_routing: lets you test whether or not the route properly resolves into
options.

 def test_movie_route_properly_splits
  opts = {:controller => "plugin", :action => "checkout", :id => "2"}
  assert_routing "plugin/checkout/2", opts
 end


assert_recognizes:  tests that an URL breaks into parameters properly.

 def test_route_has_options
  opts = {:controller => "plugin", :action => "show", :id => "12"}
  assert_recognizes opts, "/plugins/show/12"
 end


In tests you can simply pass the URL or named route to get or post.
 def send_to_jail
   get '/jail'
   assert_response :success
   assert_template "jail/front"
 end

 def goes_to_login
   get login_url
   #...
 end
