Unit Testing
In computer programming, unit testing is a procedure used to validate that individual units of source code are working properly. A unit is the smallest testable part of an application. In procedural programming a unit may be an individual program, function, procedure etc, while in object-oriented programming, the smallest unit is always a Class; which may be a base/super class, abstract class or derived/child class. Units are distinguished from modules in that modules are typically made up of units.
Ideally, each test case is independent from the others; mock objects and test harnesses can be used to assist testing a module in isolation. Unit testing is typically done by the developers and not by end-users.

The goal of unit testing is to isolate each part of the program and show that the individual parts are correct. A unit test provides a strict, written contract that the piece of code must satisfy. As a result, it affords several benefits.
