Ruby on rails 3 Rails 3的Michael Hartls教程中请求规范的标题测试失败,ruby-on-rails-3,integration-testing,capybara,Ruby On Rails 3,Integration Testing,Capybara,我正在学习MichaelHartl的RubyonRails3教程，并使用Capybara作为集成规范。目前的集成规范如下 require 'spec_helper' describe "StaticPages" do describe "Home page" do it "should have the h1 'Sample App'" do visit '/static_pages/home' page.should have_selector('h1',

我正在学习MichaelHartl的RubyonRails3教程，并使用Capybara作为集成规范。目前的集成规范如下

require 'spec_helper'

describe "StaticPages" do
  describe "Home page" do
    it "should have the h1 'Sample App'" do
      visit '/static_pages/home'
      page.should have_selector('h1',:text => 'Sample App')
    end

    it "should have the title 'Home'" do
      visit '/static_pages/home'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Home")
    end
  end

  describe "Help page" do
    it "should have the h1 'Help'" do
      visit '/static_pages/help'
      page.should have_selector('h1',:text => 'Help')
    end

    it "should have the title 'Help'" do
      visit '/static_pages/help'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Help")
    end
  end

  describe "About page" do
    it "should have the h1 'About Us'" do
      visit '/static_pages/about'
      page.should have_selector('h1',:text => 'About Us')
    end

    it "should have the title 'About'" do
      visit '/static_pages/about'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | About Us")
    end
  end
end

<html>
<head>
  <title>Ruby on Rails Tutorial Sample App | Home</title>
</head>
<body>
<h1>Sample App</h1>
<p>
This is the homepage for the sample app
</p>
</body>
</html>

当我运行这些测试时，我得到：

 1) StaticPages Home page should have the title 'Home'
     Failure/Error: page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Home")
       expected #has_selector?("title") to return true, got false
     # ./spec/requests/static_pages_spec.rb:12:in `block (3 levels) in <top (required)>'

  2) StaticPages Help page should have the title 'Help'
     Failure/Error: page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Help")
       expected #has_selector?("title") to return true, got false
     # ./spec/requests/static_pages_spec.rb:24:in `block (3 levels) in <top (required)>'

  3) StaticPages About page should have the title 'About'
     Failure/Error: page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | About Us")
       expected #has_selector?("title") to return true, got false
     # ./spec/requests/static_pages_spec.rb:36:in `block (3 levels) in <top (required)>'

1）StaticPages主页的标题应为“主页”
失败/错误：page.should应具有_选择器（'title'，：text=>“RubyonRails教程示例应用程序| Home”）
预期#has#u selector？（“title”）返回true，但返回false
#./spec/requests/static\u pages\u spec.rb:12:in'block（3层）in'
2） StaticPages帮助页面的标题应为“帮助”
失败/错误：page.should应具有_选择器（'title'，：text=>“RubyonRails教程示例应用程序|帮助”）
预期#has#u selector？（“title”）返回true，但返回false
#./spec/requests/static\u pages\u spec.rb:24:in'block（3层）in'
3） 关于页面的静态页面标题应为“关于”
失败/错误：page.should有_选择器（'title'，：text=>“RubyonRails教程示例应用程序|关于我们”）
预期#has#u selector？（“title”）返回true，但返回false
#./spec/requests/static\u pages\u spec.rb:36:in'block（3层）in'

我希望帮助和关于页面的标题测试失败，但是我的home.html.erb如下

require 'spec_helper'

describe "StaticPages" do
  describe "Home page" do
    it "should have the h1 'Sample App'" do
      visit '/static_pages/home'
      page.should have_selector('h1',:text => 'Sample App')
    end

    it "should have the title 'Home'" do
      visit '/static_pages/home'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Home")
    end
  end

  describe "Help page" do
    it "should have the h1 'Help'" do
      visit '/static_pages/help'
      page.should have_selector('h1',:text => 'Help')
    end

    it "should have the title 'Help'" do
      visit '/static_pages/help'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | Help")
    end
  end

  describe "About page" do
    it "should have the h1 'About Us'" do
      visit '/static_pages/about'
      page.should have_selector('h1',:text => 'About Us')
    end

    it "should have the title 'About'" do
      visit '/static_pages/about'
      page.should have_selector('title',:text => "Ruby on Rails Tutorial Sample App | About Us")
    end
  end
end

<html>
<head>
  <title>Ruby on Rails Tutorial Sample App | Home</title>
</head>
<body>
<h1>Sample App</h1>
<p>
This is the homepage for the sample app
</p>
</body>
</html>


Ruby on Rails教程示例应用程序|主页
示例应用程序

这是示例应用程序的主页

另外，我在/static\u pages/Home上看到了标题“RubyonRails教程示例应用程序| Home”。是什么导致home的标题测试失败？

在GEM文件中，更改

gem 'capybara'

进入

并运行“bundle update”。

Capybara 2.1更改了对查询title元素的支持。因此，使用have selector in以这种方式查询html文档头部的title元素将失败“page.should_selector（'title'，：text=>'Some text'）

使用“page.should have_title（'Some text'）”查询title元素应该有效。这是2.1 API实现的查询title元素的新方法

此外，如果您使用capybara 2x，建议将“spec”文件夹（spec/folder）中名为“requests”的子文件夹中的文件移动到名为“features”（spec/features）的新文件夹中

希望这能奏效

愉快的编码！！

谢谢。如果有人使用水豚2，会如何实现同样的效果？请尝试

page。应该有选择器（'title'，：content=>'Sample App'）

（：text已替换为：content。）这可能也会解决原来的问题。感谢您花时间回答评论。不幸的是，对于capybara 2.0.2，我得到了ArgumentError:无效键：内容，应该是以下其中之一：text、：visible、：between、：count、：max、：minimumplease mark Torstein的答案作为可接受的答案。
