Performance Testing

Performance testing requires a different mind set and skill set to that of functional testing and is best started early in the development life cycle whenever possible. Understanding customer requirements and expectations, as well as user activities and behaviors, is key to designing suitable tests.

Test environments must be carefully controlled to prevent unauthorised modifications which might falsify test results. Automated test tools coupled with fast backup and restore mechanisms are essential due to the need to repeat tests many times.

Even after performing a significant number of tests and gathering a considerable amount of data and test results there is still a possibility that the wrong conclusions may be drawn by developers inexperienced in performance testing.
