Ruby on Rails教程第3章：為什么我的測試失敗？

Question

如果有人可以幫助我弄清楚為什么我的測試失敗，那將是很大的幫助！ 我以為我完美地遵循了每個步驟，但是$ rails test命令導致失敗！ 我已撤回所有步驟，並確保沒有錯別字。 我目前正在分支中運行$rails test命令，並使用Cloud 9（雲開發環境）。

靜態頁面控制器 ：

    require 'test_helper'

class StaticPagesControllerTest < ActionDispatch::IntegrationTest
  def setup
    @base_title = "Ruby on Rails Tutorial Sample App"
  end

  test "should get home" do
    get static_pages_home_url
    puts response.body
    assert_response :success
    assert_select "title", "Home | #{@base_title}", response.body
  end

  test "should get help" do
    get static_pages_help_url
    puts response.body
    assert_response :success
    assert_select "title", "Help | #{@base_title}", response.body
  end

  test "should get about" do
    get static_pages_about_url
    puts response.body
    assert_response :success
    assert_select "title", "About | #{@base_title}", response.body
  end

end

About.html.erb ：

<% provide(:title, "About") %>
<h1>About</h1>
<p>
  The <a href="http://www.railstutorial.org/"><em>Ruby on Rails Tutorial</em></a> is a 
  <a href="http://www.railstutorial.org/book">book</a> and
  <a href="http://www.screencasts.railstutorial.org/"> screencast series</a> 
  to teach web development with 
  <a href="http://www.rubyonrails.org/">Ruby on Rails</a>.
  This is the sample application for the tutorial.
</p>

Home.html.erb

<% provide(:title, "Home") %>
<h1>Sample App</h1>
<p>
  This is the home page for the <a href="http://www.railstutorial.org/">Ruby on Rails Tutorial</a> sample application.
</p>

Application.html.erb

<!DOCTYPE html>
<html>
  <head>
    <title><%= yield(:title) %> | Ruby on Rails Tutorial Sample App</title>
    <%= csrf_meta_tags %>

    <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload' %>
    <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
  </head>

  <body>
    <%= yield %>
  </body>
</html>

對於About，Home和Help測試，我收到相同的失敗消息。 我按照一些評論者的建議添加了response.body。

這看起來像是布局錯誤。 您的斷言正在檢查諸如“關於|網站名稱”之類的字符串，但是您的輸出不包含標題標簽，它僅顯示正文，而不顯示application.html.erb中的任何內容。

您需要確保控制器使用application.html.erb中定義的布局來呈現視圖（默認情況下會發生這種情況，但是可能配置錯誤或控制器使用諸如layout: false類的東西進行呈現）。
