Performance Testing is important to check an application’s functions, response time, stability and its reliability under a given work load. It basically checks and verifies how the system performs and behaves. The significance of Software performance testing can’t be overlooked or denied in the overall App Testing process.
Difference between Performance Testing and Functional Testing.
It might be often confused with Software Functional Testing, where each function of the application is tested and verified against the functional requirements of the software whereas; the performance testing is done to validate the app’s real time performance and check defects or errors that might be present.
How is it conducted?
Testers won’t start Performance Testing until the features of the application are stable. And once any new code is available or added, Performance testing should be done immediately to assess the issues that might arise and study the feedbacks. It is done by using automated software tools such as Grinder, JMeter etc. for simulating better scenarios and to get accurate results.
This means the quality assurance testers need to have the required technical skills and a complete knowledge, in and out, about the app and internal code behavior. Working in accordance with the application developers help the Testers save a lot of time and get quicker results. Also, they should apply a continuous software testing approach to provide a real time and genuine feedback to the app developers so that they can tackle and address the related issues or system loopholes.
Performance Testing, Regression Testing and Functional testing in Software Testing using manual as well as automated tools and techniques are necessary and unavoidable phases for delivering a fully working mobile or website application. Before a product’s release, it becomes absolutely necessary to check how it responds and make sure that it evolves with the modifications carried for upgraded versions.
