WHAT ARE THE IMPORTANCE OF SOFTWARE TESTING IN IT INDUSTRY?

Importance of Testing

Web Solutions Companies uses a large number of resources and manpower to develop a particular application/software according to the requirements specified by the client. However, development of such application/software, companies are required to ensure that such application/software perform well in accordance with the client's requirements. To ensure the quality of the application/software we have to do Software Testing. There are various testing procedures available in the IT industry to check the errors and make a quality application/software. The importance of this is directly related to the ability of software to measure up to its potential. The scope of these procedure is to facilitate identification of a problem is not within the scope of Software Testing. Some of the leading methodologies of Software Testing are General, Load, Functional and Regression Testing.

General Testing

In General Testing, general tests are carried out on application/software to make sure the functionality of newly developed software. Some of the common tests included as part of Standard Quality Assurance (SQA) procedures are web performance and usability testing. The web performance testing procedure is mostly engaged in evaluating the online performance of web-based software application or a website. Usability Testing is mainly to make sure that the software is capable of being utilized effectively in a given set of circumstances. An Ecommerce Web Development Company usually performs general testing of application/software along with other more advanced methods to make sure that the software conforms to the predefined operational capabilities specified by the client.

Load Testing

The Load Testing procedure simulates operating conditions of the application/software during periods of higher/normal load to gauge the effect of such changes on the functioning of software/application. By using load testing, developers can attempt to determine the reasons for slow performance of software. The common reasons for slow response commonly include load balancing between multiple servers, client-side processing, network congestion/latency, available database service or bugs in the application servers or software. The use of Load Testing is for application which are subjected to Service Level Agreement (SLA) for making sure that the software is capable of supporting multiple users.

Functional Testing

This type of testing is a type of black-box testing based on the specifications of the software components being tested. The functions of specific components of the software are feeding inputs and checking the output thus obtained. In Functional Testing, the internal structure of the program seldom consider hence, it is classified as a type of black-box testing. Functional Testing is not the same as system testing as system testing involves validation of a program in comparison to the user requirements, whereas functional testing is carried out by checking a program with respect to established specifications and available design documents for the application/software.

REGRESSION TESTING

The Regression Testing refers to any type of software testing, which attempts to identify errors, which are present in either the functional or the non-functional areas of a system subsequent to making modifications such as configuration and patch changes. Regression Testing helps to make sure that the changes in the software do not induce changes in another part of the software's code. Some of the common regression testing methods include of earlier tests to check for alterations in program operation and the search of any previously fixed errors, which had re-emerged subsequent to introduction of the new code. Software Development Companies repeatedly perform regression testing of application/software after any change in coding such as use of patches to make sure that the functionality of the application is impaired.
