Rails 教程 haml

问：

我决定将 ruby on rails 教程从 erb 更改为 haml。我现在正在经历这个输出：

     FAIL["test_should_get_home", StaticPagesControllerTest, 0.066385842]
     test_should_get_home#StaticPagesControllerTest (0.07s)

       test/controllers/static_pages_controller_test.rb:17:in `block in    <class:StaticPagesControllerTest>'

下面是 application.rb 文件：

  %html
   %head
%meta{:content => "text/html; charset=UTF-8", "http-equiv" => "Content-Type"}/
%title
  = yield(:title)
  | Ruby on Rails Tutorial Sample App
= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true
= javascript_include_tag 'application', 'data-turbolinks-track' => true
= csrf_meta_tags
%body
= yield

那么问题来了，我如何让 haml 在测试期间将其作为一行阅读？

提前感谢您的帮助。
