How Software Testing Works?

Posted by Atul on July 8th, 2018

Software Testing is an activity in which a group of professionals simulates and executes software to check for any bug or error. Along with the errors, in software testing, it is also checked that whether the software meets the required specifications or not.

Thus, a software testing plays an important role in IT industries as the quality of the software depends on it. The working of software testing is very easy to understand as it is carried out in 4 basic levels.

In 1^st level, the software developer plays his role in software testing by performing a Unit Test on the software. In a unit test, the developer checks each unit of the coding of the software. A unit is an individual block of coding and a part of the complete program.

In 2^nd level, the software tester performs several types of software testing that includes Black Box testing, White Box testing, System testing, Regression Testing, Incremental Integration Testing, Functional Testing and so on. All these kinds of testing are performed to find different types of bugs in different ways.

The Black Box testing is done typically when the product is done building up. The analyzers execute this product testing technique to guarantee that the application is filling in according to particulars.

White Box Testing is an application's inward code and foundation testing. It centres on merging security, enhancing plan and ease of use. The System Testing is the way toward checking an incorporated programming and equipment with the goal that it can confirm that whether the system meets its predetermined necessities or not.

The Regression Testing is one of the product testing techniques to check that the application which was created and tried already is as yet performing legitimately in the wake of interfacing with other programming or not.

Nowadays, Selenium is also used for automation of Software testing but most of the companies are using conventional methods.

Similarly, other software testing techniques have their own purpose. In case, the software tester detects an error or bug, he updates and corrects the block of coding which was causing the error. After updating of the software coding, the tester again performs all these tests again on the software.

At the 3rd level of software testing, the Project Manager tests the software for its quality and errors. The Project Manager also checks that the software performs all the specified functions or not. After the verification and validation of appropriate working of the software from the Manager side, it is sent to the next level.

In 4^th and the last level, the client or the end user checks the software for proper functioning without any error. The testing of the software by the clients is essentially required so as to ensure that they are purchasing the error-free and well-functioning software.

The software testing is required for newly designed software because the occurrence of an error or bug can cost a lot to the company during its execution. Therefore, the software testing is needed.
