In computer programming, unit testing is a procedure used to validate that individual modules or units of source code are working properly. More technically one should consider that a unit is the smallest testable part of an application. In a Procedural Design a unit may be an individual program, function, procedure, web page, menu etc. But in Object Oriented Design, the smallest unit is always a Class; which may be a base/super class, abstract class or derived/child class.
