Question

我想通过rspec检查页面的标题。在chrome我看到了预期的结果但是rspec声称标题是空的（在chrome视图源中它也可以）。这里有一些代码：

application.html.rb

<!DOCTYPE html>
<html>
<head>
  <title>site | <%= yield(:title) %></title>
  <%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

home.html.erb

<% provide(:title, 'Home') %>
<h1><%= yield(:title) %></h1>
<article>
  <div><a href="#">Cameras</a></div>
  <div><a href="#">TVs</a></div>
  <div><a href="#">Laptops</a></div>
</article>

home_page_controller.rb

class HomePageController < ApplicationController
  def home
  end
end

的routes.rb

Reviewsite::Application.routes.draw do
   get "home_page/home"

home_pages_spec.rb

require 'spec_helper'
feature "HomePages" do

  before { visit '/home_page/home'}

  scenario do
    expect(page).to have_selector('h1', text: "Home")
  end

  scenario do
    expect(page).to have_selector('title', text: "site | Home")
  end

end

和错误

Failures:

  1) HomePages 
     Failure/Error: expect(page).to have_selector('title', text: "site | Home")
     Capybara::ExpectationNotMet:
       expected to find css "title" with text "site | Home" but there were no matches. Also found "", which matched the selector but not all filters.
     # ./spec/features/home_pages_spec.rb:12:in `block (2 levels) in <top (required)>'

Answer 1

我发现问题与会话有关。在您的案例中，Capybara会在每个it或scenario过期。

所以你的visit page在第一个场景中被消耗，然后第二个没有食物。

你可以尝试：

删除before { visit '/home_page/home'}部分，然后在每个方案中访问该页面。
将这两个场景合并为一个。但是，仍然优先visit放入其中。

Answer 2

而不是

expect(page).to have_selector('title', text: "site | Home")

我把它改成了

expect(page.html).to have_selector('title', text: "site | Home")

它有效，我仔细检查了一下。如果有人理解为什么单独的页面不起作用，请分享。

为什么rspec失败了？
