RoR 3.1：使用 rspec 测试正确的标题

Question

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

规范来源： https://github.com/railstutorial/sample_app/ blob/master/spec/requests/layout_links_spec.rb （我正在读这本书）

我尝试放置integrate_views和render_views，但它返回了未定义的变量错误。

$ guard
Guard is now watching at '[project dir]'
Guard::RSpec is running, with RSpec 2!

我的 Gemfile 的一部分：

gem 'rails', '3.1.0'

group :development, :test do
  gem 'turn', :require => false
  gem 'sqlite3'
  gem "rspec-rails"
  gem "factory_girl_rails"
  gem "capybara"
  gem "guard-rspec"
end

试试这个：

response.should have_xpath("//title", :text => "Name of Site | Home")
