简单的RSpec测试失败

Question

我在这里遵循这个教程,到目前为止一切都很顺利.

但是现在我已经进入了会话,一些简单的rspec测试失败了:

describe SessionsController do

  #[...]

  describe "GET 'new'" do

    it "should have the right title" do
      get :new
      response.should have_selector( "title", :content => "Sign in" )
    end

  end

  #[...]

  describe "POST 'create'" do

    #[...]

    it "should have the right title" do
      post :create, :session => @attr
      response.should have_selector("title", :content => "Sign in")
    end

    #[...]
  end

end

当我运行rspec时,我总是得到:

1)SessionsController GET'new'应该有正确的标题失败/错误:response.should have_selector("title",:content =>"登录
)预期后面的输出包含一个登录标记:w3.org/TR/REC -html40/loose.dtd">#./ spec/control/session_controller_spec.rb:14:在'块(3级)中'

当我访问会话/新页面时,该页面包含如下标题标记:

<title>Ruby on Rails Tutorial Sample App | Sign in</title> 

为什么那些测试失败,而所有其他类似的(=标题标签测试)测试工作正常？

这是SessionController:

class SessionsController < ApplicationController
  def new
    @title = 'Sign in'
  end

  def create

    user = User.authenticate( params[:session][:email], params[:session][:password] )

    if user.nil?
        flash.now[:error] = "Invalid email/password combination."
        @title = 'Sign in'
        render 'new'
    else
        sign_in user
        redirect_to user
    end
  end


    def destroy
        sign_out
        redirect_to root_path       
    end

end

我在这做错了什么？

谢谢你的帮助

您需要添加render_views到班级的顶部.没有它,将不会生成实际的html,并且您的have_selector测试将失败.
