Question

我正在使用Michaels Hartls Ruby on Rails教程。在第3章中，我按照说明设置了R Spec和autotest。到目前为止，我已经完成了教程中指示的所有内容，但我不断收到此错误消息。

rspec ./spec/controllers/pages_controller_spec.rb:13 # PagesController GET 'home' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:31 # PagesController GET 'contact' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:43 # PagesController GET 'about' should have the right title
rspec ./spec/controllers/pages_controller_spec.rb:57 # PagesController GET 'help' should have the right title'

我的Gemfile显示

source 'https://rubygems.org'

gem 'rails', '3.2.3'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'

我的application.html.erb显示

  <!DOCTYPE>
<html>
    <head>
        <title><%= title %></title>
        <%= csrf_meta_tag %>
        </head>
    <body>
        <%= yield %>
    </body>
</html>

我的page_controller_spec.rb显示了这个

 require 'spec_helper'

describe PagesController do
render_views
#home

  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 => @base_title + " | Home")
     end

     it "should have a non-blank body" do
  get 'home'
  response.body.should_not =~ /<body>\s*<\/body>/
end
 end 
  #contact

  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 => @base_title + " | Contact")
  end
  end
#about
  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 =>  @base_title  + "  | About")
    end 
    end

    #help

  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 => @base_title + "| Help")
    end 
    end  
  end

pages_helper.rb有

module PagesHelper


      # Return a title an a per-page basis
    def title
      base_title = "Ruby on Rails Tutorial Sample App"
      if @title.nil?
        base_title
      else
        "#{base_title} | #{@title}"
      end
    end
    end

pages_controller.rb有

class PagesController < ApplicationController

  def home
        @title = 'home'
     end

  def contact
    @title = 'contact'
  end

  def about
    @title = 'about'
  end

   def help
    @title = 'help'
  end


end

浏览器中的一切都很好。但是当我的测试使用rspec spec / ..

运行时，我仍然会遇到这些错误

有人可以帮忙吗？

Answer 1

您需要设置@base_title。您可以在使用它之前在规范中的任何位置设置它，但因为它在任何地方都可以将它放在before块中，即

before(:each) do
  @base_title = ...
end

您也可以使用let（但规格需要使用base_title而不是@base_title

rspec ./spec/controllers/pages_controller_spec.rb:13#PagesController GET'home'应该有正确的标题
