Feature: engine routes

  Routing specs can specify the routeset that will be used for the example
  group. This is most useful when testing Rails engines.

  Scenario: specify engine route
    Given a file named "spec/routing/engine_routes_spec.rb" with:
    """ruby
    require "spec_helper"

    # A very simple Rails engine
    module MyEngine
      class Engine < ::Rails::Engine
        isolate_namespace MyEngine
      end

      Engine.routes.draw do
        resources :widgets, :only => [:index]
      end

      class WidgetsController < ::ActionController::Base
        def index
        end
      end
    end

    describe MyEngine::WidgetsController do
      routes { MyEngine::Engine.routes }

      it "routes to the list of all widgets" do
        expect(:get => widgets_path).
          to route_to(:controller => "my_engine/widgets", :action => "index")
      end
    end
    """
    When I run `rspec spec`
    Then the examples should all pass
