我在测试 RoR 教程中的代码时遇到错误，请帮助解决这些问题，清单如下。可能是 Gemfile 中规范的错误版本。

失败：

  1) PagesController GET 'home' should have the right title
     Failure/Error: response.should have_selector("title", :content => "Home")
     NoMethodError:
       undefined method `has_selector?' for #<ActionController::TestResponse:0x007fb3d4d2d108>
     # ./spec/controllers/pages_controller_spec.rb:14: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")
     NoMethodError:

宝石文件：

source 'https://rubygems.org'

gem 'rails', '3.2.3'

gem 'sqlite3'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

end

gem 'jquery-rails'

group :test, :development do
  gem "rspec-rails", "~> 2.10.1"
end

pages_controller_spec.rb 清单：

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

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

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

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

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

我不明白出了什么问题。

如果你不想使用 webrat，你可以使用

response.body.should include 'Contact</h1>'

而不是

response.should have_selector("title", :content => "Contact")

我同意，这有点不干净。

重新编辑您的 GEMFILE 并输入

gem 'webrat'

接着

类型

bundle install
