A non-functional testing technique called performance testing is used to evaluate the system's responsiveness and stability under various loads. Performance testing assesses the system's attributes, such as dependability, scalability, and resource usage. Performance testing focuses on how a system performs while handling a certain load. The purpose of this is not to find software vulnerabilities or defects. Different performance testing approaches take results measurements in relation to standards and benchmarks. Performance testing assists developers in locating bottlenecks and removing them.
