What is Software Testing • Software testing is a process of executing a program or application with the intent of finding software error bugs. Software testing is more than just error detection. • Software testing is the process of validation Verification of the software service or application or program by checking whether it ’ s meeting the requirements mentioned in the FSD Functional Requirements Document which is working as expected and what all is implemented as per the characteristics.

Why Software Testing • The purpose is to check whether the software satisfies the specific requirements needs and expectations of the customer who will be using the software. There can be many reasons for defects in the software. The developer can also make an error which may result in a defect or bug in the software source code. Any defect or bug in the software will produce wrong results causing a failure. When a bug or defect occurs in a software application testing is done to find out the cause of defect and to remove the bug. • Software testing with strict test execution assures lower maintenance cost. There cannot be any failures because it can be very expensive in the later stages of the development. Copyright 2015 Learntek. All Rights Reserved. 4
