Rspec-rails：测试布局是否包含样式或javascripts

Question

I want to test if my 'style.css' is linked to my page while rendering it with a certain layout, for example 'application.html.erb': 我想测试我的'style.css'是否链接到我的页面，同时使用某个布局呈现它，例如'application.html.erb'：

So here's the spec: 所以这是规范：

spec/views/layouts/application.html.erb_spec.rb 规格/视图/布局/ application.html.erb_spec.rb

  it 'should include styles for screen media' do
    render
    rendered.should have_selector('link',
      :href => '/stylesheets/style.css',
      :media => 'screen',
      :rel => 'stylesheet',
      :type => 'text/css'
    )
  end

And my application.html.erb looks like: 我的application.html.erb看起来像：

app/views/layouts/application.html.erb 应用程序/视图/布局/ application.html.erb

<html>
  <head>
    <meta content="text/html; charset=utf-8" http-equiv="content-type">
    <%= stylesheet_link_tag :style, :media => 'screen' %>
    <%= javascript_include_tag :defaults %>
    <%= csrf_meta_tag %>
  </head>
  <body>
    <%= yield %>
  </body>
</html>

When I run my view spec, it fails because 当我运行我的视图规范时，它失败了，因为

<link href="/stylesheets/style.css?1289599022" media="screen" rel="stylesheet" type="text/css">

is rendered, and 渲染，和

<link rel='stylesheet' type='text/css' media='screen' href='/stylesheets/reset.css'/>

is expected. 是期待。

And it's all about the numbers '?1289599022' rails adding after the filename. 这就是数字'？1289599022'在文件名后添加的栏目。 Any ideas on how to test this functionality? 有关如何测试此功能的任何想法？

Answer 1

Try using the Rails stylesheet_path() helper instead... this will generate the URL with the timestamp for you. 尝试使用Rails stylesheet_path（）帮助器代替...这将生成带有时间戳的URL。

it 'renders a link to the stylesheet' do
  render
  rendered.should have_selector('link',
    :rel => 'stylesheet',
    :media => 'screen',
    :href => stylesheet_path('style')
  )
end

I've been running into the same problem today and it's been extremely frustrating. 我今天遇到了同样的问题而且非常令人沮丧。 I tried the solution above but did not have access to the stylesheet_path (I am using an rspec controller test but am rendering the view directly from the controller test). 我尝试了上面的解决方案，但没有访问stylesheet_path（我正在使用rspec控制器测试，但直接从控制器测试渲染视图）。 I tried including the necessary module to make it work but that just gave me other errors. 我尝试包含必要的模块以使其工作，但这只是给了我其他错误。 Eventually, I decided to just change rails in test mode such that it will not generate the asset timestamp. 最后，我决定只在测试模式下更改rails，这样它就不会生成资产时间戳。

Simply edit your test.rb to include the line: 只需编辑test.rb即可包含以下行：

ENV['RAILS_ASSET_ID'] = '' ENV ['RAILS_ASSET_ID'] =''

inside of 代替

Testapp::Application.configure do ... end Testapp :: Application.configure做...结束
