failing integration test

I am following the Ruby on Rails tutorial here:

http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=2.3

I am at this section:

http://ruby.railstutorial.org/chapters/filling-in-the-layout?version=2.3#code:layout_links_spec

Here is my layout_links_spec.rb:

require 'spec_helper'

describe "Layout links" do   it "should have a Home page at '/'" do     get '/'     response.should render_template('pages/home')   end

  it "should have a Contact page at '/contact'" do     get '/contact'     response.should render_template('pages/contact')   end

  it "should have an About page at '/about'" do     get '/about'     response.should render_template('pages/about')   end

  it "should have a Help page at '/help'" do     get '/help'     response.should render_template('pages/help')   end      it "should have a signup page at '/signup'" do     get '/signup'     response.should render_template('users/new')   end end

Here is my routes.rb:

ActionController::Routing::Routes.draw do |map|   map.contact '/contact', :controller => 'pages', :action => 'contact'   map.about '/about', :controller => 'pages', :action => 'about'   map.help '/help', :controller => 'pages', :action => 'help'   map.home '/', :controller => 'pages', :action => 'home'      map.signup '/signup', :controller => 'users', :action => 'new' end

When I do a "spec spec/" I get 5 tests failed:

1) NoMethodError in 'Layout links should have a Home page at '/'' undefined method `match' for :Array /home/di/rails_projects/sample_app/spec/integration/layout_links_spec.rb:5:

2) NoMethodError in 'Layout links should have a Contact page at '/contact'' undefined method `match' for :Array /home/di/rails_projects/sample_app/spec/integration/layout_links_spec.rb:10:

3) NoMethodError in 'Layout links should have an About page at '/about'' undefined method `match' for :Array /home/di/rails_projects/sample_app/spec/integration/layout_links_spec.rb:15:

4) NoMethodError in 'Layout links should have a Help page at '/help'' undefined method `match' for :Array /home/di/rails_projects/sample_app/spec/integration/layout_links_spec.rb:20:

5) NoMethodError in 'Layout links should have a signup page at '/signup'' undefined method `match' for :Array /home/di/rails_projects/sample_app/spec/integration/layout_links_spec.rb:25:

All the links work in the web browser. I am using Ruby 1.8.7 and Rails 2.3.8. Why are my tests failing?

Thanks in advance for the help.
