Perhaps the most important tip for performance testing is testing early, test often. Unlike load testing, stress testing also known as fatigue testing is meant to measure system performance outside of the parameters of normal working conditions. This is an essential step in order to make sure the end-to-end specifications of a system are met. In software testing, recovery testing is the activity of testing how well an application is able to recover from crashes, hardware failures and other similar problems. Conducting performance testing in a test environment that is similar to the production environment is a performance testing best practice for a reason. If recovery is automatic, i.e., performed by the system itself, then re-initialization, data recovery, and system restarts are evaluated for correctness. Repeat the test to confirm each problem has been conclusively eliminated. Do not infer minimum performance and requirements based upon load testing. Its a key step in ensuring software quality, but unfortunately, is often seen as an afterthought, in isolation, and to begin once functional testing is completed, and in most cases, after the code is ready to release. You can help Wikipedia by expanding it. The goal of stress testing is to measure the software stability. Recovery testing is the forced failure of the software to verify if the recovery is successful. Also known as load size.
