TestClass（Rails）的Rspec作用域问题

当我分别运行这些rspec文件时，它们都通过了，当我一起运行时，它们失败了

似乎当我运行

@application\u presenter=descripted\u class.new（TestClass.new，view\u context）

时，它使用了ActAsAttribute\u spec.rb中的TestClass

这似乎是一个范围问题。我认为RSpec.descripe是有名称空间的。处理这一冲突的最佳方式是什么？我可以更改TestClass的名称，但我更喜欢一种更好的方法，即确保我的类等在每个

Rspec.description

块中都有名称空间
