Question

我是StackOverflow的新手，因为我最近开始使用Michael Hartl的教程学习Ruby on Rails。我似乎无法通过上市8.25的测试（＆＃34;此时，测试套件仍然应该是GREEN：＆＃34; $ bundle exec rake test）：

我的测试是红色，错误如下：

~/workspace/sample_app (log-in-log-out) $ bundle exec rake test
Started

ERROR["test_layout_links", SiteLayoutTest, 2016-04-14 23:15:47 +0000]

我再次经历了第7章和第8章的所有最新变化; 8.20,8.21和8.24的测试刚刚通过。

错误中提到的文件site_layout_test如下所示：

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

test "layout links" do
  get root_path
  assert_template 'static_pages/home'
  assert_select "a[href=?]", root_path, count: 2
  assert_select "a[href=?]", help_path
  assert_select "a[href=?]", about_path
  assert_select "a[href=?]", contact_path
  get signup_path
  assert_select "title", full_title("Sign up")
  end
end

加法：

1）这是我正在做的教程：https://www.railstutorial.org/book/log_in_log_out

2）这是错误引用的文件：

require 'test_helper'

class SiteLayoutTest < ActionDispatch::IntegrationTest

test "layout links" do
  get root_path
  assert_template 'static_pages/home'
  assert_select "a[href=?]", root_path, count: 2
  assert_select "a[href=?]", help_path
  assert_select "a[href=?]", about_path
  assert_select "a[href=?]", contact_path
  get signup_path
  assert_select "title", full_title("Sign up")
  end
end

如果我把最后一个assert_select拿出来，我就不会再收到错误了。

这就是application_helper：

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

非常感谢您的帮助。提前谢谢！

我打赌原因是因为你没有执行Listing 5.37中的步骤，其中包含ApplicationHelper test_helper.rb中的class ActiveSupport::TestCase fixtures :all include ApplicationHelper . . . end：

<ul class="inbox-message-list">
<li class="message-suject">
  This is some long text that will not fit in the box

</li>
</ul>

在Michael Hartl的Rails教程的第8章中，列出了8.25测试套件RED
