Ruby on rails Rspec测试失败Hartl教程第9.1章-编辑用户标题失败

我仍然停留在编辑用户第9.1.1章的测试中，尽管我已经解决了第一组错误消息——感谢你们在这方面的帮助。 一个新的测试失败错误出现在我所在的位置，我被鼓励提出一个新问题。我会把我的更新代码放在这里

我正在运行这个测试：$bundle exec rspec spec/requests/user\u pages\u spec.rb-e“edit page” 我只是不知道错误是从哪里来的，经过大量的搜索。 我还更新了水豚2.0.0

Failures:

  1) User pages signup edit page 
     Failure/Error: it { should have_selector('title', text: "Edit user") }
     Capybara::ExpectationNotMet:
       expected to find css "title" with text "Edit user" but there were no matches. Also found "",         which matched the selector but not all filters.
     # ./spec/requests/user_pages_spec.rb:60:in `block (5 levels) in <top (required)>'

Finished in 0.56475 seconds
3 examples, 1 failure

这是我修改过的用户控制器：

class UsersController < ApplicationController

  def show
    @user = User.find(params[:id])
  end

  def new
    @user = User.new
  end

   def create
    @user = User.new(params[:user])
    if @user.save
      sign_in @user
      flash[:success] = "Welcome to the Your App!"
      redirect_to @user
    else
      render 'new'    
      end
    end

  def edit
    @user = User.find(params[:id])
  end
end

以及头文件html.erb

<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
    <div class="container">
        <%=link_to "sample app", root_path, id: "logo" %>

看起来您的描述块嵌套可能有误

'用户页面注册编辑页面'

这表明编辑页面嵌套在“注册”中，它应该位于用户页面下

这可能会导致上下文错误

为标题{'Edit user'}尝试

content\u

这一行没有改变Error header标记也没有关闭，尽管它可能是一个片段。header标记是原始的。谢谢Michael。谢谢@Muttollamb我会研究一下。你建议从哪里学习Rails惯例中的嵌套？这不是关于Rails中的嵌套，而是关于如何在RSpec中设置测试上下文。vario美国级别的descripe块设置了不同的上下文。我已经更新了答案以提供帮助-基本上我认为您的do，end是无序的为了在用户页面下嵌套编辑页面，我是否需要更改缩进或移动descripe部分（最后16行左右）向上？区块是否需要以不同的顺序放置？我正在尝试研究hartl在github上的代码。如果您复制代码，并与您的初始帖子进行比较，在开始描述“编辑”之前，有一个和结束描述“注册”，这是唯一的更改。不幸的是，我添加了额外的“结束”，但它没有更改e错误：（我当然清理了代码-谢谢@muttonlab的提示
