测试规范,来自railstutorial第3章的capybara不起作用(have_selector(‘title’,：text =>’| Home’))

我在 ruby.railstutorial.org/ruby-on-rails-tutorial-book上工作.
我使用导轨3.2.7,spork,rspec,capybara,launchy和一些守卫:)

在第3章中,我有一个非常奇怪的问题：测试：

似乎测试并不适用于< head> -Tag内的内容.如果我将< title> – 标签放在< body> – 标签内,而不是标题,它可以正常工作.
当我将< h1> – 标签放在< title>在< head> -Tags内.这是奇怪的,不是吗？

请帮我弄清楚.

示例来自：ruby.railstutorial.org/chapters/static-pages#code:title_test：

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

错误消息是：

Failures:

1) Static pages Home page should have the title ‘Home’
Failure/Error: page.should have_selector(‘title’,:text => ‘ | Home’)
Capybara::ExpectationNotMet:
expected to find css “title” with text ” | Home” but there were no matches. Also found “”,which matched the selector but not all
filters.
# ./spec/requests/static_pages_spec.rb:15:in `block (3 levels) in ‘

那一个正在工作：

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

呈现的HTML文件：

<!DOCTYPE html>
<html>
<head>
  <title>Ruby on Rails Tutorial Sample App | Home</title>
  <!-- some css,js stuff -->
</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>

谢谢

我所做的说明
主页的代码就像它应该是.
关于页面的代码具有自己的布局,在标题标签之上带有h1标签,以显示它的工作原理.
最后,帮助页面的标题标签也在正文标签内.

我绝对困惑,为什么我有这样一个奇怪的行为？

解决方法

我刚刚检查了你在Github上的项目,似乎你正在使用边缘版本的capybara：

的Gemfile

gem 'capybara',:git => 'git://github.com/jnicklas/capybara.git'

Gemfile.lock的

GIT
  remote: git://github.com/jnicklas/capybara.git
  revision: e561d249555195cdd0e9251246fc75aae876f833
  specs:
      capybara (2.0.0.beta2)
      mime-types (>= 1.16)
      nokogiri (>= 1.3.3)
      rack (>= 1.0.0)
      rack-test (>= 0.5.4)
      selenium-webdriver (~> 2.0)
      xpath (~> 1.0.0.beta1)

如果没有别的,我敢说这是你问题的原因. (当然,在更新capybara之后,我的reference project全部坏了,使用边缘版本)

因此,除非您热衷于帮助Capybara 2的beta测试,否则您将很乐意遵守here所列的1.1.2版本.
