Ruby on rails RoR静态页面帮助页面的标题应为'；帮助'；

我正在学习Michael Hartl的Ruby on Rails教程，我正在做第5章的练习。有人能解释一下为什么这次考试不及格吗

我的路线.rb

SampleApp::Application.routes.draw do
  root 'static_pages#home'
  match '/help',    to: 'static_pages#help',    via: 'get'
  match '/about',   to: 'static_pages#about',   via: 'get'
  match '/contact', to: 'static_pages#contact', via: 'get
end

我的静态页面\u spec.rb

require 'spec_helper'

describe "Static pages" do

  let(:base_title) { "Ruby on Rails Tutorial Sample App" }

  describe "Home page" do

    it "should have the h1 'Sample App'" do
      visit root_path
      expect(page).to have_content('Sample App')
    end

    it "should have the base title" do
      visit root_path
      expect(page).to have_title("Ruby on Rails Tutorial Sample App")
    end

    it "should not have a custom page title" do
      visit root_path
      expect(page).not_to have_title('| Home')
    end
  end

  describe "Help page" do

    it "should have the h1 'Help'" do
      visit help_path
      expect(page).to have_content('Help')
    end

    it "should have the title 'Help'" do
      visit help_path
      expect(page).to have_title("Ruby on Rails Tutorial Sample App | Help")
    end
  end

  describe "About page" do

    it "should have the h1 'About Us'" do
      visit about_path
      expect(page).to have_content('About Us')
    end

    it "should have the title 'About Us'" do
      visit about_path
      expect(page).to have_title("Ruby on Rails Tutorial Sample App | About Us")
    end
  end

  describe "Contact page" do

    it "should have the content 'Contact'" do
      visit contact_path
      expect(page).to have_content('Contact')
    end

    it "should have the title 'Contact'" do
      visit contact_path
      expect(page).to have_title("Ruby on Rails Tutorial Sample App | Contact")
    end
  end
end

看起来您的测试很好，所以您的测试可能失败了，因为标题实际上没有正确设置

我想您只需要在视图中添加以下内容：

<% provide(:title, 'Title') %>

---

或者确保您发送的标题与您测试的标题相同。

如果没有查看代码，我们无法查看您是否真的访问此页面。试着查看服务器控制台，看看是否有302错误。我没有得到302错误，我添加了日志服务器，我可以打开/about和/help页面。但我不确定它是否正常工作并通过了测试。这可能是因为您的标题实际上没有在视图中设置吗？是的。。。我没有在适当的文件中添加和。谢谢，伙计们。酷，我正确地回答了下面的问题。顺便说一句。。。为什么我们需要使用跌落试验？我现在不明白。只需检查一下测试是否完全有效？当使用TDD（测试驱动开发）时，我们在通过测试（绿色）之前先编写失败的测试（红色），因为这样我们就更有信心测试正确的东西。如果我们看到测试以我们期望的方式失败，我们可以相当肯定我们的测试正在工作。您不必先测试（TDD），但它通常被认为是Ruby社区的最佳实践。哈特尔对何时进行测试有一个旁白：我希望这回答了你的问题。如果我误解了你的要求，请告诉我。另外，我注意到你是新来的。如果您认为此答案有帮助，可以将其标记为已接受的答案。了解更多有关接受StackOverflow答案的信息：谢谢，本杰明，我了解坠落测试。至少我这么认为：）。我认为这种练习会帮助我更多更好地理解。

<% provide(:title, 'Title') %>
