The stability, speed, scalability, and responsiveness of an application are evaluated using the non-functional software testing technique known as performance testing. It’s a crucial stage in guaranteeing the quality of software, but regrettably, it’s frequently treated as an afterthought, done in isolation, and started after functional testing is finished, and in most cases, after the code is prepared for release.
Performance testing’s objectives include assessing the output of the application, its processing speed, data transfer rate, network bandwidth usage, the number of concurrent users at their maximum, memory usage, workload efficiency, and command reaction times.
To assess how well a system’s components function under a specific workload, performance testing is done. The stability of the system under test is confirmed by monitoring system components during this testing. An example of a non-functional test is performance testing.
