I'm building my first webapp on Rails 3.0.10 and trying to right my title tests in my Pages_Controller_Spec as I learned from the ruby on rails tutorial book, however even though the titles are correct in the browser, the tests are failing. I have installed Capybara, but haven't used it yet - is that 开发者_运维技巧potentially interfering?

You'll see it's very basic right now, but I want to start from the ground up with a solid testing suite. Any help would be much appreciated!

Here is my spec: (The simple "should be_success pass fine)

require 'spec_helper'

describe PagesController do

  render_views

   describe "GET 'home'" do

    it "should be successful" do
      get 'home'
      response.should be_success
    end

    it "should have the right title" do
      get 'home'
      response.should have_selector("title", 
                  :content => "Home")
    end

  end

  describe "GET 'contact'" do
    it "should be successful" do
      get 'contact'
      response.should be_success
    end

    it "should have the right title" do
      get 'contact'
      response.should have_selector("title", :content => "Contact")
    end

  end

end

I'm rendering the title in the application layout like this:

<!DOCTYPE html>
<html>
<head>
  <title><%= @title %></title>
  <%= stylesheet_link_tag :all %>
  <%= javascript_include_tag :defaults %>
  <%= csrf_meta_tag %>
</head>
<body>

<%= yield %>

</body>
</html>

Here is how I'm setting the instance variable:

<% @title = "Home" %>

<h1>Pages#home</h1>
<p>Find me in app/views/pages/home.html.erb</p>

EDIT: Here is the test output

Failures:

1) PagesController GET 'home' should have the right title
Failure/Error: response.should have_selector("title",
expected css "title" to return something
# ./spec/controllers/pages_controller_spec.rb:15:in `block (3 levels) in <top (required)>'

2) PagesController GET 'contact' should have the right title
Failure/Error: response.should have_selector("title", :content => "Contact")
expected css "title" to return something
# ./spec/controllers/pages_controller_spec.rb:29:in `block (3 levels) in <top (required)>'

Finished in 0.14245 seconds
4 examples, 2 failures

EDIT 2: Adding what puts response.body

Running: spec/controllers/pages_controller_spec.rb
.<!DOCTYPE html>
<html>
<head>
  <title>Home</title>

</head>
<body>


<h1>Pages#home</h1>
<p>Find me in app/views/pages/home.html.erb</p>


</body>
</html>

Turns out I didn't have WebRat installed as a gem. I guess this came from me taking my testing gems from railscast and using some of the tests I learned in the Hartl tutorial.

Thanks for the help!
