node 私有方法的测试 rewire

Question

 37  describe('hello',function(){
 38   describe('#selfFunction',function(){
 39     it("should be test even if it's private",function(){
 40       var rewireFunction = rewire('./private.js')
 41       console.log('rewireFunction is',rewireFunction);
 42       var privateFunction = rewireFunction._get_('selfFunction');
 43       chai.expect(privateFunction(2)).equal(3);
 44     })
 45   })
 46 })

如上所示代码，为什么总告诉我 _get_ 方法不存在呢？我引入了 rewire 模块了啊

Answer 1

应该是 set 和 get

Answer 2

是 __get__,也就是 两个下划线get两个下划线
