Rails pages_controller_spec.rb 测试不应该失败，而是错误吗？

Question

一直在学习Michael Hart的Rails教程rails 3.0版在mac OS X 10.7 上

Failed examples:
rspec ./spec/controllers/pages_controller_spec.rb:44 # PagesController GET 'help' should be successful
rspec ./spec/controllers/pages_controller_spec.rb:48 # PagesController GET 'help' should have the right title

测试如下：

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 => "Ruby on Rails Tutorial Sample App | 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 => "Ruby on Rails Tutorial Sample App | 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 => "Ruby on Rails Tutorial Sample App | 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 => "Ruby on Rails Tutorial Sample App | Help")
    end
  end
end

我在pages_controller.rb

class PagesController < ApplicationController
  def home
    @title = "Home"
  end
  def contact
    @title = "Contact"
  end
  def about
    @title = "About"
  end
  def help
    @title = "Help"
  end
end

在路线上。rb我有

SampleApp::Application.routes.draw do
  get "pages/home"
  get "pages/contact"
  get "pages/about"
  get "pages/help"
end

当然，我还在app/views/pages中创建了一个help.html.erb页面奇怪的是，当我运行rails服务器并转到localhost:3000/pages/help时，我得到了具有正确标题的正确页面，使其看起来好像测试应该通过了，但它没有通过。此外，联系人、家庭和关于测试都通过了，但当我刚刚添加帮助时，由于某种未知原因，它没有通过。这真的让我很烦恼，我忽略的让我发疯的简单解决方案是什么？

Answer 1

下载您的代码并运行：

........
8 examples, 0 failures
Finished in 0.18184 seconds

它正在运行GET"help"，所以我认为您正在自动测试中运行它，而不是重新加载。可能的

Answer 2

您的代码很好。问题是您以前的代码被缓存了。通过退出终端并打开一个新窗口，您可以有效地清除缓存。如果不在测试环境中关闭缓存，您可能会遇到同样的问题。转到config/environments/test.rb并将config.cache_classes = true更改为config.cache_classes = false
