What is Performance Testing?

Definition of Performance Testing?

There is no single-approved-definition of performance testing in the books, here is how I define performance testing:

An empirical technical investigation conducted to provide stakeholders with information about the quality of the product or service under test with regard to speed, scalability, reliability, stability characteristics and/or resource usage under a specific workload is called as Performance Testing.

Performance testing can serve different purposes.

• It can demonstrate that the system meets performance criteria.
• It can compare two systems to find which performs better.
• Or it can measure what parts of the system or workload causes the system to perform badly.
