红宝石轨道3-迈克尔哈特指南第5章rspec问题

Question

当我完成了题为"填写布局"的第5章以及用户的初始创建后，我运行了rspec，得到了以下内容：

1) PagesController GET 'home' should have the right title
 Failure/Error: response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | Home")
   expected following output to contain a <title>Ruby on Rails Tutorial Sample App | Home</title> 
2) PagesController GET 'contact' should have the right title
 Failure/Error: response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | Contact")
   expected following output to contain a <title>Ruby on Rails Tutorial Sample App | Contact</title> 
3) PagesController GET 'about' should have the right title
 Failure/Error: response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | About")
   expected following output to contain a <title>Ruby on Rails Tutorial Sample App | About</title>

我已经做了大约一天了，我只是不知道我做错了什么？此外，页面启动也非常好

这是页面控制器代码需要"spec_helper"

describe PagesController do
  render_views
  describe "GET 'home'" do
    it "should be successful" do
      get 'home'
      response.should be_success
    end
    it "should have the right title" do
      get 'home'
      response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | Home")
    end
  end
  describe "GET 'contact'" do
    it "should be successful" do
      get 'contact'
      response.should be_success
    end
    it "should have the right title" do
      get 'contact'
      response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | Contact")
    end
  end
  describe "GET 'about'" do
    it "should be successful" do
      get 'about'
      response.should be_success
    end
    it "should have the right title" do
      get 'about'
      response.should have_selector("title", :content => "Ruby on Rails Tutorial Sample App | About")
    end
  end
end

这里还有我的应用程序/views/layouts/application.html.erb

<title><%= @title %></title>

这是我的布局_links_spec

require 'spec_helper'

it "should have a Home page at '/'" do
  get '/'
  response.should have_selector('title', :content => "Home")
end
it "should have a Contact page at '/contact'" do
  get '/contact'
  response.should have_selector('title', :content => "Contact")
end
it "should have have an About page at '/about" do
  get '/about'
  response.should have_selector('title', :content => "About")
end
it "should have a Help pageat '/help'" do
  get '/help'
  response.should have_selector('title', :content => "Help")
end
it "should have a signup page at '/signup'" do
  get '/signup'
  response.should have_selector('title', :content => "Sign up")
end
it "should have the right links on the layout" do
  visit root_path
  response.should have_selector('title', :content => "Home") 
end
end

Answer 1

确保包含render_views

require 'spec_helper'
describe UsersController do
  render_views
  describe "GET 'new'" do
    it "should be successful" do
      get :new
      response.should be_success
    end
    it "should have the right title" do
      get :new
      response.should have_selector("title", :content => "Sign up")
    end
  end
end

Answer 2

我花了一些时间才弄清楚确切的错误是什么，但请确保按照Mike教程中的说明进行操作。

迈克的工作效率很高，也很彻底，但如果你跳过一步就会出错。我看到了同样的问题，首先您需要确保使用的是列表5.20中更新最多的static_pages_spec.rb，列表5.23的更新最多的路由文件，并确保删除了publicindex.html文件。

一旦你完成了这些步骤，你的错误就会消失。
