有人可以识别我的代码中的错误导致我的测试失败吗？

Question

我继续运行此测试并且它一直失败，但我找不到错误。失败消息是：

  

[故障：     StaticPagesControllerTest＃test_should_get_contact [/ Users / iThompkins / Documents / SiteDev / environment / sample_app / test / controlle   RS / static_pages_controller_test.rb：26]：

<Contact | Ruby on Rails Tutorial Sample App> expected but was
<Ruby on Rails Tutorial Sample App>..
Expected 0 to be >= 1.]

我的测试如下：

require 'test_helper'

class StaticPagesControllerTest < ActionDispatch::IntegrationTest

   test "should get home" do

    get static_pages_home_url
    assert_response :success
    assert_select "title", "Ruby on Rails Tutorial Sample App"
 end

 test "should get help" do
   get static_pages_help_url
   assert_response :success
   assert_select "title", "Help | Ruby on Rails Tutorial Sample App"
 end

 test "should get about" do
   get static_pages_about_url
   assert_response :success
   assert_select "title", "About | Ruby on Rails Tutorial Sample App"
 end

 test "should get contact" do
   get static_pages_contact_url
   assert_response :success
   assert_select "title", "Contact | Ruby on Rails Tutorial Sample App"
 end
end

我的控制器

class StaticPagesController < ApplicationController
  def home
  end

  def help
  end

 def about
 end

 def contact
 end
end

和我的观点

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

Answer 1

您的观点的标题部分是否有print (df.stack()) 0 Value1 0.0 Value2 1.0 1 Value1 2.0 Value2 4.0 2 Value2 3.0 dtype: float64 ？

<%= yield(:title) %>

从Hartl book开始，您需要生成标题值才能显示它。
