What is Unit Testing?

Overview

Unit testing is a testing method of a unit - the smallest piece of code that can be logically isolated in a system. In most programming languages, it is a function, a subroutine, a method, or a property.

A unit is a testable part of a software system and is tested during the development phase of the application software. Unit testing can be defined as a type of software testing where individual components of the software are tested. Unit testing of a software product is performed during the development of an application. An individual component can be either an individual task or a process.

Unit Testing is usually performed by using the White Box Testing method and is normally automated. It is the first level of functional testing and involves testing each unit or a separate component of a software application. The purpose behind unit testing is to validate the unit components along with their performance.
