私有函数有办法进行mock吗？

[yourenawo]

我现在在补以前写的代码，有些函数是私有的，需要mock掉。

Convey("TestApplyPrivateMethod", t, func() {
        Convey("patch private pointer method in the different package", func() {
            f := new(fake.PrivateMethodStruct)
            var s *fake.PrivateMethodStruct
            patches := ApplyPrivateMethod(s, "ok", func(_ *fake.PrivateMethodStruct) bool {
                return false
            })
            defer patches.Reset()
            result := f.Happy()
            So(result, ShouldEqual, "unhappy")
        })

        Convey("patch private value method in the different package", func() {
            s := fake.PrivateMethodStruct{}
            patches := ApplyPrivateMethod(s, "haveEaten", func(_ fake.PrivateMethodStruct) bool {
                return false
            })
            defer patches.Reset()
            result := s.AreYouHungry()
            So(result, ShouldEqual, "I am hungry")
        })

        Convey("repeat patch same method", func() {
            var s *fake.PrivateMethodStruct
            patches := ApplyPrivateMethod(s, "ok", func(_ *fake.PrivateMethodStruct) bool {
                return false
            })
            result := s.Happy()
            So(result, ShouldEqual, "unhappy")

            patches.ApplyPrivateMethod(s, "ok", func(_ *fake.PrivateMethodStruct) bool {
                return true
            })
            result = s.Happy()
            So(result, ShouldEqual, "happy")

            patches.Reset()
            result = s.Happy()
            So(result, ShouldEqual, "unhappy")
        })
    })

这个是private method的mock，可以为私有函数mock吗
