Quality assurance and testing
The main agenda behind performing software testing is to achieve a bug-free application. Companies benefit with software tester as it surfs through any website on mobile phones, desktop, tablets, and other devices. Thus, the developers are bound to put extra effort in developing a responsive web application. A little bug under the nose itself can create problems that will allow hackers to steal any private data.
This is exactly why we perform software testing for quality assurance. This step is crucial because it helps in identifying errors or bugs from the system at the beginning itself.
