我一直在搜索网络和 Stack Overflow 以了解如何让这些测试正常工作。我是 Ruby 和 Rails 的新手，我只是按照 Hartl 的教程进行操作 - 复制粘贴大部分代码，看看它们最终是如何结合在一起的。

现在，我陷入了第 3.3 节“稍微动态的页面”中。

这是我收到的错误：

C:\Sites\sample_app>bundle exec rspec --no-color spec/requests/static_pages_spec.rb
F.F.F.

Failures:

  1) Static pages About page should have the title 'About Us'
 Failure/Error: page.should have_selector('title',
   expected css "title" with text "Ruby on Rails Tutorial Sample App | About Us" to return something
 # ./spec/requests/static_pages_spec.rb:44:in `block (3 levels) in <top (required)>'

  2) Static pages Help page should have the title 'Help'
 Failure/Error: page.should have_selector('title',
   expected css "title" with text "Ruby on Rails Tutorial Sample App | Help" to return something
 # ./spec/requests/static_pages_spec.rb:29:in `block (3 levels) in <top (required)>'

  3) Static pages Home page should have the title 'Home'
 Failure/Error: page.should have_selector('title',
   expected css "title" with text "Ruby on Rails Tutorial Sample App | Home" to return something
 # ./spec/requests/static_pages_spec.rb:14:in `block (3 levels) in <top (required)>'

一旦我从这个 HTML 结构（在我的 About/Home/Help.html.erb 文件中）切换，就会发生错误：

<% provide(:title, 'Home') %>
<!DOCTYPE html>
<html>
  <head>
    <title>Ruby on Rails Tutorial Sample App | <%= yield(:title) %></title>
  </head>
  <body>
  <h1>Sample App</h1>
    <p>
      This is the home page for the
      <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
      sample application.
    </p>
</body>
</html>

对此： 

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

其他相关文件：

应用程序.html.erb： 

<!DOCTYPE html>
<html>
  <head>
    <title>Ruby on Rails Tutorial Sample App | <%= yield(:title) %></title>
    <%= stylesheet_link_tag    "application", :media => "all" %>
    <%= javascript_include_tag "application" %>
    <%= csrf_meta_tags %>
  </head>
  <body>
    <%= yield %>
  </body>
</html>

static_pages_spec.rb

require 'spec_helper'

describe "Static pages" 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")

     // The line below is something I tried replacing the page.should have_selector with
    // page.should have_xpath("//title", :text => "Home")
  end
end

.... (other describe pages, same structure)

end

我可能只是在复制/粘贴/阅读 Hartl 教程的过程中失明了，但我非常确定它看起来和他描述的一样。

我已经尽力寻找解决方案，但可惜我无法弄清楚，所以就这样吧！

干杯!

在这个网址上：“http://localhost:3000/static_pages/home”

文档标题什么都不是。

文档的来源如下所示：

<h1>Sample App</h1>
<p>
  This is the home page for the
  <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
  sample application.
</p>

源代码中没有 doctype、head、body 或 title 声明。

为了让 Rails 获取布局文件，application.html.erb 文件应该位于 app/views/layouts/application.html.erb 中。
