Introduction

Earlier this week, I met a friend of mine and we started discussing and chit-chatting about things from here and there. I don't remember the exact context of the conversation, but I remember a crux of it.

So I asked him a question, I asked Smith did you ever wrote Unit Tests for the applications you develop?

He very politely told me, Smile I don't have time for writing a test case . Plus I don't need them as I know my code works.

Have you ever encountered such answers or gave such answers to your fellow developers?
