Question

我正在运行Rails 3.0.1和Rspec 2.0.1。我正在关注M. Hartl的Ruby on Rails教程，并且在第5课：填充布局时遇到了测试失败的问题。

当我运行自动测试时，不断收到此错误并且似乎无法弄清楚原因：

Answer 1

您遇到的问题是您的测试中有

response.should have_selector('title', :content => "Sign Up")

但您的HTML代码是

 <title>Ruby on Rails Tutorial Sample App | Sign up</title>

您的测试和HTML源代码不匹配。在源代码中大写“up”，你会很高兴。

Answer 2

我认为这是一个案例问题。内容不必完全匹配，但案例确实如此。

是的......诺亚说的话。
