Ruby on rails 添加引导下拉菜单后无法通过rspec测试

我正在学习Michael Hartl的Rails教程，我正在向应用程序添加一个引导下拉顶部导航栏，该导航栏根据用户是否登录而变化

这是使导航条改变的代码

<% if signed_in? %>
        <li><%= link_to "Users", '#' %></li>
        <li id="fat-menu" class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown">
            Account <b class="caret"></b>
          </a>
          <ul class="dropdown-menu">
            <li><%= link_to 'Profile', current_user %></li>
            <li><%= link_to 'Settings', '#' %></li>
            <li class="divider"></li>
            <li>
              <%= link_to 'Sign out', signout_path %>
            </li>
          </ul>
        </li>
      <% else %>
        <li><%= link_to 'Sign in', signin_path %></li>
      <% end %>

在保存并重新加载应用程序后，我使一切正常工作

但是，即使应用程序代码本身正常工作，rspec测试也失败了

Failures:

     Failure/Error: it { should have_link('Sign out',    href: signout_path) }

它说，链接恰好嵌套在下拉菜单中，没有返回true

rspec规范中的路径与应用程序代码中使用的路径相同，您可以看到应用程序正在使用rspec中描述的相同路径/链接重定向您

发生了什么事？

我认为，您的规范无法在引导下拉菜单中找到您的链接。我想，你只需点击那个下拉列表，它就能找到那个链接。试试这个：

describe "with valid information" do
  let(:user) { FactoryGirl.create(:user) }   

    before do
      visit '/signin'
      fill_in "Email",    with: user.email.upcase
      fill_in "Password", with: user.password
      click_button "Sign in"
    end

    click_link "Account"

    it { should have_title(user.name) }
    it { should have_link('Profile',     href: user_path(user)) }
    it { should have_link('Sign out',    href: signout_path) }
    it { should_not have_link('Sign in', href: signin_path) }
end 

尝试：

 it { should have_link('Profile',     href: user_path(user), visible: false) }

或

我在这里找到了一个适合我的答案：

有关部分：

考虑到我需要在更改个人资料之前有效登录，我将其添加到了我的用户_pages_spec.rb中

 it { should have_link('Profile',     href: user_path(user), visible: false) }

describe "with valid information", js: true do
  # before
  click_link "Account"

context "edit" do
let(:user) { FactoryGirl.create(:user) }
before { sign_in user }  <------------
before { visit edit_user_path(user) }
