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 "rails_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

      RSpec.describe MyEngine::WidgetsController, :type => :routing 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
