我已经尝试过这么多来解决我自己的问题，我也用Google搜索了但是我无法解决它，＆amp;我也是铁杆上的红宝石以及黄瓜的新手。如果我错了，请指导我，我的帮助将不胜感激。谢谢

如果仔细观察堆栈跟踪：

   And I am exists as a parent      # features/step_definitions/kid_steps.rb:106
   undefined local variable or method `role' for #<Cucumber::Rails::World:0xc4722f8> (NameError)
  ./features/step_definitions/event_steps.rb:10:in `create_visitor'
  ./features/step_definitions/event_steps.rb:14:in `create_user'
  ./features/step_definitions/kid_steps.rb:107:in `/^I am exists as a parent$/'
  features/manage_kids.feature:11:in `And I am exists as a parent'

即使执行了undefined local variable or method 'role'的方法，您也会发现错误消息./features/step_definitions/event_steps.rb:10以及引发错误create_visitor的源代码的位置。

查看您发布的来源时：

def create_visitor
  @visitor ||= { :email => "user@example.com",
    :password => "test123", 
    :password_confirmation => "test123", 
    :role => Role.find_by_name(role.to_s)} # i assume that this is line 10!
end

您可以看到您正在呼叫role。从您发布的代码中，没有定义role的位置。必须有一个变量或具有该名称的方法。也许这只是一个错字，你的意思是一个实例变量@role。

我们可以为您提供更多帮助，这些都在您的代码中......

为什么我在黄瓜测试用例中得到未定义的局部变量或方法“角色”
