使用规范进行测试,railstutorial 第 3 章中的水豚不起作用 (have_selector('title', :text => ' | Home'))

2024-02-18

我正在处理 ruby​​.railstutorial.org/ruby-on-rails-tutorial-book。 我使用 Rails 3.2.7、spork、rspec、capybara、launchy 和一些 Guards :)

我在第三章的测试中遇到了一个非常奇怪的问题:

看来测试对里面的内容不起作用<head>-标签。如果我把<title>- 标签内<body>-tag 而不是 head-tag 效果很好。 当我放置时它也有效<h1>- 上面的标签<title> inside <head>-标签。这很奇怪,不是吗?

请帮我弄清楚。

该示例来自: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:

失败:

1) 静态页面主页标题应为“Home” 失败/错误: page.should have_selector('title', :text => ' | Home') 水豚::未满足期望: 期望找到带有文本“| Home”的 css“标题”,但没有匹配项。还找到了“”,它匹配选择器但不是全部 过滤器。 # ./spec/requests/static_pages_spec.rb:15:in `block (3 level) in '

那个正在工作:

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

渲染的 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>

Thanks

我所做的解释: 主页的代码应该是这样的。 about 页面的代码有自己的布局,内部标题标签上方有一个 h1 标签,以表明它出于某种原因工作。 最后,帮助页面的标题标签位于正文标签内,这也有效。

我非常困惑,为什么我会有如此奇怪的行为?

只是因为<title>在里面<head>所以它没有出现。

使用这个,解决了我的问题:

page.should have_selector 'title', :visible => false

提示:您可以应用相同的方法来检查其他<head>元素,例如<meta>,例如,确保您(并且您将保持)对 Google 友好。
