Question

我有一个带有“事件”模型的Rails应用程序，在'spec / features'目录中，我有一个'list_events_spec.rb'文件和一个'show_event_spec.rb'文件。当放入'list_events'规范时，以下3个断言使我的RSpec测试崩溃，但是当我将断言置于'show_event'规范中时，测试通过了。页眉，页脚和旁边都是在application.html.erb文件中呈现的部分内容。

我唯一可以想到的是Rails根据文件名对这两个文件的处理方式不同，但我希望断言无论它们放在哪个spec_file中都能正常工作，因为它们是在application.html中呈现的。 .erb文件。

以下是断言（文件名为“_header.html.erb”，“_ footer.html.erb”和“_sidebar.html.erb”）：

it "has a header" do
  expect(page).to have_selector("header")
end

it "has a footer" do
  expect(page).to have_selector("footer")
end

it "has a sidebar" do
  expect(page).to have_selector("aside")
end

这是application.html.erb文件：

<!DOCTYPE html>
<html>
  <head>
    <title>EventsTdd</title>
    <%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
    <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
    <%= csrf_meta_tags %>
  </head>
  <body>
    <%= render 'header' %>
    <%= render 'sidebar' %>
    <%= yield %>

  </body>
  <%= render 'footer' %>

</html>

这是RSpec错误消息：

为什么我的RSpec断言在一个视图规范而不是另一个视图规范上工作？
