我正在完成Michael Hartl 的 Ruby on Rails 教程第 5 章练习，但我不断收到一个我无法弄清楚的失败测试。

我正在处理 click_link 问题，并且所有大写字母都匹配，并且我相信所有其他文件都是正确的。我真的不确定这里有什么问题。我试过重新启动Spork。每当我注释掉第一个 click_link 测试时，它都会为第二个测试拉出一个错误，依此类推...随意查看http://github.com/sambaek/sample_app上的代码。

有人可以帮我吗？非常感谢！

问题是因为你的链接layouts/footer没有layouts/header去任何地方。它们可以按规范点击，但它们只是转到#而不是正确的页面。如果您更正这些链接，则规范将起作用。

在app/views/layouts/_footer.html.erb：

<li><%= link_to "About",   '/about' %></li>
<li><%= link_to "Contact", '/contact' %></li>

在app/views/layouts/_header.html.erb：

 <li><%= link_to "Home",    '/' %></li>
 <li><%= link_to "Help",    '/help' %></li>

为什么不继续使用命名的路由路径变量（例如 about_path）？
