The Importance Of Testing Computer Software
Software is an important component of a computer upon which the performance of a computer depends. However, with the technological revolution that takes place in the field of computer and technology on daily basis, computer technology undergoes frequent change. Therefore, in order to provide the proper functioning of a computer, it becomes very important that the software utility is maintained in an efficient way so that it provides efficient functioning. Therefore, testing computer software is an important way of maintaining the computer. Given the prevalent use of computer in various fields such as schools, health services, research, defense, banks, offices and business houses, it becomes very important that the software that is handling crucial database is updated and fault free. In order to provide this service, various IT organizations employ well qualified computer programmers and professionals who are dedicated towards research and design of a zero error and high utility program that serves in an efficient way. Therefore, given the high end utility of computer and the Internet, it is immensely important that testing computer software is carried out on routine basis. This will ensure high efficiency of the system. Software engineers who design the software ensure that the work which is assigned to perform by the software is carried out without fail so that there are no technical glitches. Therefore, as a software tester and quality analyst the software tester looks into the intricacy of the program and its system files so that it is free from malfunction. In order to check the software, there is regression software that looks into the proper and timely functioning of stipulated task. The feedback that is the outcome of this software ensures the quality of the software and its functioning. This practice varies from software to software and its utilities. In technical terms, this method is known as Software Quality Assurance that looks for the efficiency, security and reliability of the software. Basically, testing computer software involves three techniques such as White Box, Black Box and Grey Box testing. In the While Box technique the internal structure of software is done that often involves checking its algorithms, codes and performing debugging. In the Grey Box testing method, one checks the input value, SQL value and output value in order to know the proper functioning of software. In the Black Box testing technique, only the input and output is tested. This is the method that is involved for verification and validation purposes. Some of the other ways of testing computer software include unit testing, integration testing, functional testing, system testing, system integration testing and acceptance testing. However, these tests appear easy to an onlooker, yet the creation of software undergoes a series of checks such as requirement analysis which is performed during creating phase of the software. This is followed by the test plan, development, and execution and reporting.
On the basis of testing computer software, it is awarded with certifications that add to its success and utility. Therefore, testing computer software is an important process that deals with the software development and creation.
