Michael Hartl的rails教程第3章，rspec中的錯誤

Question

我是Ruby on Rails的新手。目前使用特立獨行的10.9.3，Rails 4.我嘗試運行rspec命令時出現以下錯誤。

這裏是錯誤，我得到：

rspec ./spec/controllers/pages_controller_spec.rb:35 # PagesController GET 'about' should have the right title 
rspec ./spec/controllers/pages_controller_spec.rb:24 # PagesController GET 'contact' should have the right title 
rspec ./spec/controllers/pages_controller_spec.rb:11 # PagesController GET 'home' should have the right title 

我的Gemfile包括：

group :development, :test do 
    gem 'rspec-rails', '2.14.2' 
end 

group :test do 
    gem 'rspec', '2.14.1' 
    gem 'spork', '0.9.0.rc' 
end 

也是我pages_controller_spec.rb

require 'spec_helper' 

describe PagesController do 
    render_views 

    describe "GET 'home'" do 
    it "returns http success" 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 "returns http success" 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 "returns http success" 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 
end 

從下面的評論

控制器代碼：

class PagesController < ApplicationController 
    def home 
    end 

    def contact 
    end 

    def about 
    end 
end 

Answer 1

您是否嘗試過檢查的文檔： https://relishapp.com/rspec

Answer 2

是那麼簡單的小寫字母「A」大約VS關於？

您的測試正在尋找字符串「Ruby on Rails教程示例應用程序|關於」，代碼正在生成「Ruby on Rails教程示例應用程序|關於」。據我所知，rspec是區分大小寫的。

我看到的另一件事是必須設置：對於測試標題是可見的。
