预期响应为 <:redirect>，但实际响应为 <200>

我的 rspec 测试遇到问题，浏览了之前的问题后我无法解决它。测试失败并出现上述错误，但代码在实践中有效，有谁知道如何解决这个问题？

Rspec:

describe "authentication of edit/update pages" do

    before(:each) do
        @user = Factory(:user)
    end

    describe "for non-signed in users" do
        it "should deny access to 'edit'" do
            get :edit, :id => @user
            response.should redirect_to(signin_path)
        end

        it "should deny access to 'update'" do
            put :update, :id => @user, :user => {}
            response.should redirect_to(signin_path)
        end
    end
end

会话助手：

def deny_access
    redirect_to signin_path, :notice => "Please sign in to access this page."
end

用户控制器

class UsersController < ApplicationController
before_filter :authenticate, :only => [:edit, :update]
  private
    def authenticate
        deny_access unless signed_in?
    end
end

我想你应该稍微改变你的代码：

def deny_access
  redirect_to signin_path, :notice => "Please sign in to access this page." and return
end
