Definition

Software testing is an execution of a software program or system to determine one or more of its characteristics. It consists of various methods to test and declare a software product fit before it can be launched for use by either an individual or a group.

Overview

Testing techniques can be grouped roughly into three classes: (1) random testing involves selection of data across the environment, often with some frequency distribution; (2) structural testing involves generating test cases from a program itself, forcing known behavior onto the program; and (3) functional testing uses the specified functions of a program as the basis for defining test cases."[1]
