当我将设计模块添加到我的 Rails 应用程序时，我的测试出现错误

application.html.erb 在哪里

<!DOCTYPE html>
<html>
    <head>
        <title>Judgement</title>
        <%= stylesheet_link_tag    "application", :media => "all" %>
        <%= javascript_include_tag "application" %>
        <%= csrf_meta_tags %>
    </head>
    <body>
        <nav>
            <% if user_signed_in? then %>
            <%= link_to "You are #{current_user.email}", edit_user_registration_path %>
            <%= link_to "Exit", destroy_user_session_path, { :method => :delete,
                                                             :confirm => "Are you sure"} %>
            <% else %>
            <%= link_to "Sign In", new_user_session_path %>
            <%= link_to "Register", new_user_registration_path %>
            <% end %>
        </nav>
        <%= yield %>
        <div class="notice">
            <%= notice %>
        </div>
        <div class="alert">
            <%= alert %>
        </div>
    </body>
</html>

所以这看起来像错误，因为“user_signed_in？” 帮手。但我不明白错误的意义何在。

我对所有 Rails 魔法都不是很熟悉。

更新：已解决

我必须添加

class ActionController::TestCase
  include Devise::TestHelpers
end

到我的 test/test_helper.rb

我建议使用此功能：https ://gist.github.com/989413 。您的测试将更加孤立。在你的罐子里，你可以像这样存根：helper.stub(:user_signed_in?) {false}。函数 user_signed_in? 应该根据需要返回 true 或 false。

这里有一个类似的问题：Testing helpers in Rails 3 with Rspec 2 and Devise

编辑测试::单元

它认为你应该重新定义一个用 Test::Unit 模拟的方法。像这样的东西：

module Devise
  module Controllers
    module Helpers    
      def user_signed_in?
        true #Return false if you want
      end
    end
  end
end

如果您将其用于 rspec 中的视图规范，您需要将其存根于view，而不是helper.

allow(view).to receive(:user_signed_in?).and_return(true)
