Rails - Mar 2014 - Rails Engine ActionController::UrlGenerationError on functional tests

Hi,

I'm looking for a way to solve an error I get each times I run my 
functional tests. I have a Rails Engine gem (isolated), I have a JSON 
action with a route declared. But each times I use the method get in a test 
I get an ActionController::UrlGenerationError exception.

Here an example of code with the problem:

# config/routes.rbMyEngine::Engine.routes.draw do
  resources :cats, only: [:show], format: 'json'end
# test/dummy/config/routes.rbRails.application.routes.draw do
  mount MyEngine::Engine => '/my_engine'end
# app/controllers/my_engine/cats_controller.rbmodule MyEngine
  class CatsController < ApplicationController
    def show
      render json: { hello: 'world' }
    end
  endend
# test/controllers/my_engine/cats_controller_test.rbmodule MyEngine
  class CatsControllerTest < ActionController::TestCase
   test 'should get success' do
      get :show, id: 42

      assert_response :success
    end
  endend

Here is an example of test return:

1) Error:
MyEngine:: CatsControllerTest#test_should_get_success:
ActionController::UrlGenerationError: No route matches
{:action=>"show", :controller=>"my_engine/cats",
:id=>"42"}


Anyone have an idea to solve this problem?

Thanks.
