如何扩展“应该”库

Question

我想介绍一下应该断言库，用于我的node.js应用程序的测试以及其他功能。

伪代码中的内容

should      = require "should"

myExists = (obj, msg) ->
  # my special exist logic

containSomething = (obj, msg) ->
  # my special assert logic

should.myExists = myExists
should.containSomething = containSomething


describe.only "`my extra `", ->
   it 'should be working', (done) ->
     obj = {}
     obj.should.myExists  
     obj.should.not.myExists  
     obj.should.containSomething {cool:obj}
     obj.should.not.containSomething {cool:obj}
     done()

任何建议如何在实践中做到这一点？

Answer 1

should.myExits = myExists

应该是

should.myExist = myExists
