What is THE UNIT in a unit test? And what should it be?

A unit is the smallest testable part of the application, usually a function.

The term (similar to many other things associated with Agile) is overloaded (means different things to different people). It has undergone a lot of flux and is now subjective. Some have come up with a new term microtests to prevent confusion.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
