Topic: Non-functional testing

The scope of performance testing is not well defined and varies from creating scripts and running tests in its narrow definition to all kinds of performance-related activities when synthetic workload is applied to the system in its wide definition. And the wide definition often includes performance analysis, performance troubleshooting / diagnostics, tuning, and capacity planning making the word “testing” to be rather disguising the substance of what it behind. The difference behind these definitions can partly explain the wide range of opinions about a path from functional testing to performance testing: while the path from automated functional testing to “narrow definition” performance testing is quite straightforward, skills required by other areas of “wide definition” performance testing are quite different.
