I am following the Ruby on Rails Tutorial for Rails 3, located here:

http://ruby.railstutorial.org

I am at this section of the tutorial:

http://ruby.railstutorial.org/chapters/filling-in-the-layout#sec:integration_tests

All of my pages render as expected at this point; e.g., I can hit http://localhost:3000/about and see the about page of the sample application, with the expected title (“Ruby on Rails Tutorial Sample App | About”). Yet the integration tests from this section keep failing.

Here is my layout_links_spec.rb:

require 'spec_helper'

describe "LayoutLinks" do

  it "should have a Home page at '/'" do
    get '/'
    response should have_selector('title', :content => "Home")
  end

  it "should have a Contact page at '/contact'" do
    get '/contact'
    response should have_selector('title', :content => "Contact")
  end

  it "should have an About page at '/about'" do 
    get '/about'
    response should have_selector('title', :content => "About")
  end

  it "should have a Help page at '/help'" do
    get '/help'
    response should have_selector('title', :content => "Help")
  end
end

When I run tests with rspec spec/ or via autotest, I get the following test failures:

    ........FFFF

    Failures:

      1) LayoutLinks should have a Home page at '/'
         Failure/Error: response should have_selector('title', :content => "Home")

      4) LayoutLinks should have a Help page at '/help'

    Failed examples:

    rspec ./spec/requests/layout_links_spec.rb:20 # LayoutLinks should have a Help page at '/help'

…note that the response shown in the test failures appears to indicate that I’m getting a mock/stubbed response. I believe that this is my issue, but I don’t know why it is happening.

    I figured it out. I typed in the tests above myself. When I re-copied/pasted the tests directly from the tutorial, they began passing. I was mystified, as everything looked identical at a glance. But after running a diff, I realized that for each test, I had typed:

    response should

    …but that I should have typed:

    # Note the "."
response.should

    After making this correction to each test, they all pass as expected.
