i want to check page's title through rspec. in chrome i see the expected result but rspec claim the title is empty(in chrome view source it also ok). here some code:
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
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
and the error
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.
