What is the purpose of performance testing in QA?

The purpose of performance testing in Quality Assurance is primarily centered around measuring the responsiveness and speed of an application. This type of testing evaluates how well an application performs under a particular workload. It focuses on parameters such as response time, throughput, reliability, and resource usage to ensure that users have a smooth experience when interacting with the software.

Through performance testing, QA teams can identify bottlenecks and issues that may affect the application's performance before it reaches the end users. An application that performs well under expected and peak loads is crucial for maintaining user satisfaction, which is why this type of testing is essential in the QA process. By concentrating on responsiveness and speed, teams can ensure that applications meet not only technical standards but also user expectations in real-world usage scenarios.
