我想通过 rspec 检查页面的标题。在 chrome 中我看到了预期的结果，但 rspec 声称标题为空（在 chrome 视图源中它也可以）。这里有一些代码：

应用程序.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>

主页.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

路线.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)>'

编辑： 这是我的 gemfile

end

group :assets do
  gem 'sass-rails',   '3.2.6'

end

end

我看到问题是关于会话的。Capybara 在每个it或scenario您的情况下过期会话。

因此，您visit page在第一种情况下被消耗掉了，然后在第二种情况下没有食物可吃。

您可以尝试：

  1. 删除before { visit '/home_page/home'}部件，并在每个场景中访问页面。
  2. 将这两种情况合二为一。但是，仍然visit是首选放在里面。

代替

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

我把它改成

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

它有效，我仔细检查了它。如果有人理解为什么单独的页面不起作用，请分享。
