コンテキストブロックで "respond_with：success"を呼び出すときに "method_missing"エラーが発生するのはなぜですか？ここ

Question

はエラーとテストの要旨です：https://gist.github.com/1445801

そして、ここではその要旨の内容は以下のとおりです。

require 'test_helper' 

class Api::HotelsControllerTest < ActionController::TestCase 

    context "When not logged in" do 
     should "forbid access when creating a hotel" do 
      hotel = Factory.build(:hotel) 
      post :create, :hotel => hotel 
      assert @response.code == "401" 
      assert Hotel.count.zero? 
     end 

     should "forbid access when listing available hotels" do 
      get :available 
      assert @response.code == "401" 
     end 

     should "forbid access when listing hotels" do 
      get :index 
      assert @response.code == "401" 
     end 

     should "forbid access when showing a hotel" do 
      hotel = Factory(:hotel) 
      get :show, :id => hotel.id 
      assert @response.code == "401" 
     end 

     should "forbid when updating a hotel" do 
      hotel = Factory(:hotel) 
      hotel.name = "Some new Hotel name" 
      put :update, :id => hotel.id, :hotel => hotel 
      assert @response.code == "401" 
     end 
    end 

    context "When logged in as basic user" do 
     setup do 
      @user = Factory(:user) 
      sign_in @user 
     end 

     context "on GET available hotel with no search criteria" do 
      setup do 
       get :available 
      end 

      should respond_with :success 
      should "be valid response" do 
       true 
      end 
     end 
    end 

end 

とテスト：成功、should respond_with(:success)：周りの括弧を含む

てみてください。

Answer 2

私は同じ問題（Shoulda - 2.11.3と同じ名前のコントローラとあなたのような名前空間のコントローラ）を持っていて、Shouldaを3.1.1にアップグレードして修正しました。
