当我将设计模块添加到我的rails应用程序时,我的测试会出错

application.html.erb的位置

<!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.但我无法理解错误的重点.

我对所有Rails魔法都不太熟悉.

UPD：已解决

我必须补充一下

class ActionController::TestCase
  include Devise::TestHelpers
end

到我的test / test_helper.rb

解决方法

我建议使用这个功能： https://gist.github.com/989413.你的测试会更加孤立.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Test :: Unit

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
