Question

我正在研究Michael Hartl的Ruby on Rails教程，我正在进行第5章练习。有人可以解释为什么这个测试失败了吗？

我的routes.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static_pages_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

看起来你的测试很好，所以你的测试可能会失败，因为标题实际上没有正确设置。

我想你只需要在你的观点中添加这样的东西：

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

或确保您发送的标题与您正在测试的标题相同。

RoR静态页面帮助页面的标题应为＆＃39;帮助＆＃39;
