[Routes][Gem] assert can't see route

Hello,

I have problem with routes in my gem. I have this example code for adding routes : module ActionDispatch::Routing     class Mapper        def gallery_for         match "/gallery/get/:id" => "gallery/ view#get", :as=>:gallery_galleries_by_user_id        end     end end And I'm trying to test it by : class RoutestTest < ActionController::TestCase   test 'map gallery get' do     puts Rails.application.routes.routes     assert_routing '/gallery/get/1', :controller => "gallery/ view", :action => "get"   end end I added puts Rails.application.routes.routes to see routes. Then I try to test it I get :    /gallery/get/:id(.:format) {:controller=>"gallery/ view", :action=>"get"} E

Error: test_map_gallery_get(RoutestTest): ActionController::RoutingError: No route matches "/gallery/get/1" What I'm doing wrog or is it any rails bug ?
