Question

我对其中一个练习中的测试有一个非常具体的问题。我已经通过所有不同的文件追溯到失败，无法看到导致问题的原因。我将从失败消息开始。

FAIL["test_profile_display", UsersProfileTest, 1.204680988099426]
 test_profile_display#UsersProfileTest (1.20s)
        <Michael Example | Ruby on Rails Tutorial Sample App> expected but was
        <Michael ExampleMichael Example | Ruby on Rails Tutorial Sample App>..
        Expected 0 to be >= 1.
        test/integration/users_profile_test.rb:13:in `block in <class:UsersProfileTest>'

可以看出，我的灯具文件中的名称出现两次而不是一次。

以及产生故障的相应测试：测试/集成/ users_profile_test.rb：

require 'test_helper'

class UsersProfileTest < ActionDispatch::IntegrationTest
  include ApplicationHelper

  def setup
    @user = users(:michael)
  end

  test "profile display" do
    get user_path(@user)
    assert_template 'users/show'
    assert_select 'title', full_title(@user.name)
    assert_select 'h1', text: @user.name
    assert_select 'h1>img.gravatar'
    assert_match @user.microposts.count.to_s, response.body
    assert_select 'div.pagination'
    @user.microposts.paginate(page: 1).each do |micropost|
      assert_match micropost.content, response.body
    end
  end
end

以上代码的违规行为

assert_select 'title', full_title(@user.name)

这里是与用户的夹具文件：迈克尔的名字＆＃34;迈克尔的例子＆＃34;出现两次但应该只出现一次。

测试/装置/ users.yml里

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: <%= Time.zone.now %>
.
.
.

这是该夹具用于创建标题的代码

应用程序/助手/ application_helper.rb

module ApplicationHelper

  # Returns the full title on a per-page basis.
  def full_title(page_title = '')
    base_title = "Ruby on Rails Tutorial Sample App"
    if page_title.empty?
      base_title
    else
      page_title + " | " + base_title
    end
  end
end

为什么当代码声明在页面标题中只出现一次时，用户夹具的名称会出现两次？

编辑：

应用程序/视图/ layouts.application.html.erb

<!DOCTYPE html>
<html>
  <head>
    <title><%= full_title(yield(:title)) %></title>
    <%= render 'layouts/rails_default' %>
    <%= render 'layouts/shim' %>
  </head>
  <body>
    <%= render 'layouts/header' %>
    <div class="container">
      <% flash.each do |message_type, message| %>
      <%= content_tag(:div, message, class: "alert alert-#{message_type}") %>
      <!--<div class="alert alert-<%= message_type %>"><%= message %></div>-->
      <% end %>

      <%= yield %>
      <%= render 'layouts/footer' %>
      <%= debug(params) if Rails.env.development? %>
    </div>
  </body>

编辑2：users / show.html.erb

<% provide(:title, @user.name) %>
<div class="row">
  <aside class="col-md-4">
    <section class="user_info">
      <h1>
        <%= gravatar_for @user %>
        <%= @user.name %>
      </h1>
    </section>
  </aside>
    <div class="col-md-8">
    <% if @user.microposts.any? %>
      <h3>Microposts (<%= @user.microposts.count %>)</h3>
      <ol class="microposts">
        <%= render @microposts %>
      </ol>
      <%= will_paginate @microposts %>
    <% end %>
  </div>

</div>

Answer 1

app / views / users / show.html.erb

<div class="row">
  <aside class="col-md-4">
    <section class="user_info">
      <h1>
        <%= gravatar_for @user %>
        <%= @user.name %>
      </h1>
    </section>
  </aside>
  <div class="col-md-8">
    <% if @user.microposts.any? %>
      <h3>Microposts (<%= @user.microposts.count %>)</h3>
      <ol class="microposts">
        <%= render @microposts %>
      </ol>
      <%= will_paginate @microposts %>
    <% end %>
  </div>
</div>````
