簡單的Rspec測試失敗邁克爾哈特爾RoR Tuotiral

Question

我是一個總新手，我正在學習邁克爾哈特爾的教程Ruby on Rails。我在第3章，關於頁面的Rspec測試失敗（雖然完全相同的測試對於主頁和幫助頁面並不失敗）。

運行$ bundle exec rspec spec/requests/static_pages_spec.rb當我得到的錯誤是：

Failures: 

1) Static pages About page should have the content 'About Us'←[31mFailure/Error:←[0m ←[31mvisit 'static_pages/about'←[0m←[31mURI::InvalidURIError←[0m:←[31mthe scheme http does not accept registry part: www.example.com:80static_pages (or bad hostname?)←[0m←[36m  # ./spec/requests/static_pages_spec.rb:24:in `block (3 levels) in <top (required)>'←[0m Finished in 0.0776 seconds←[31m3 examples, 1 failure←[0m 

Failed examples: 

←[31mrspec ./spec/requests/static_pages_spec.rb:23←[0m ←[36m# Static pages About page should have the content 'About Us'←[0m 

當訪問http://localhost:3000/static_pages/about頁面加載，我可以在大H1字母見「關於我們」。

規格/請求/ static_pages_spec.rb：

require 'spec_helper' 

describe "Static pages" do 

    describe "Home page" do 

    it "should have the content 'Sample App'" do 
     visit '/static_pages/home' 
     expect(page).to have_content('Sample App') 
    end 
    end 

    describe "Help page" do 

    it "should have the content 'Help'" do 
     visit '/static_pages/help' 
     expect(page).to have_content('Help') 
    end 
    end 

    describe "About page" do 

    it "should have the content 'About Us'" do 
     visit 'static_pages/about' 
     expect(page).to have_content('About Us') 
    end 
    end 
end 

配置/ routes.rb中：

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

應用程序/控制器/ static_pages_controller.rb：

class StaticPagesController < ApplicationController 
    def home 
    end 

    def help 
    end 

    def about 
    end 
end 

應用程序/視圖/ about.html.erb：

<h1>About Us</h1> 
<p> 
    The <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> 
    is a project to make a book and screencasts to teach web development 
    with <a href="http://rubyonrails.org/">Ruby on Rails</a>. This 
    is the sample application for the tutorial.

我注意到你錯過了最初的/在失敗的測試：

visit 'static_pages/about' 

VS

visit '/static_pages/help'
