不在spec/controllers中的rspec 2的測試軌控制器

Question

rspec預計您的控制器規格在/ spec/controllers中。我有一些模塊包含在我的控制器中。據我所知，測試它們的唯一方法是創建一個虛擬控制器，將模塊包含在其中，並從那裏進行測試。問題在於模塊規格在/ spec/lib/module中，所以ControllerExampleGroup不包含在內，這意味着我無法調用幫助器方法獲取「動作」等。

我可以手動導入這些我得到了大部分的路，但我然後得到這個錯誤：

建議？類型屬性的描述方法：

describe MyController, :type => :controller do 
    ... 
end 

對於間距標準即意味着要包含的模塊

Answer 1

如果你有一個規範，這不是標準的地區之一，你可以隨時通過傳遞告訴rspec的通過控制器，rspec 2可以非常方便地創建匿名控制器。

describe MyModule do 

    context "when included by a controller", :type => :controller do 
     controller do  # anonymous subclass of ActionController::Base 
      include MyModule 

      def index 
       head :ok 
      end 
     end 

     it "works" do 
      get "index" 
      response.should be_success 
     end 
    end 
end
