ruby-on-rails – 匿名控制器的Rspec stubing视图

测试目前看起来像这样：

describe ApplicationController do
  controller do
    before_filter :authenticated

    def index      
    end
  end

  describe "user authenticated" do
    let(:session_id){"session_id"}
    let(:user){OpenStruct.new(:email => "pythonandchips@gmail.com",:name => "Colin Gemmell")}

    before do
      request.cookies[:session_id] = session_id
      UserSession.stub!(:find).with(session_id).and_return(user)
      get :index
    end

    it { should assign_to(:user){user} }

  end
end

应用程序控制器是这样的：

class ApplicationController < ActionController::Base
  protect_from_forgery

  def authenticated
    @user = nil
  end
end

我的问题是,当我运行测试我得到以下错误

1) ApplicationController user authenticated 
   Failure/Error: get :index
   ActionView::MissingTemplate:
     Missing template stub_resources/index with {:handlers=>[:erb,:rjs,:builder,:rhtml,:rxml,:haml],:formats=>[:html],:locale=>[:en,:en]} in view paths "#<RSpec::Rails::ViewRendering::PathSetDelegatorResolver:0x984f310>"

根据文档,视图不是rendered when running controller tests,但是这表示这个动作没有存根(这是可以理解的,因为视图不存在)

任何人都有一个线索,如何解决这个问题或存根的看法.
