Performance Testing Metrics

Performance Test Engineers do their job really well. But for a long term project, it is much important to accomplish the task by spending optimum effort. “Who cares about metrics? My job is scripting, execution and result analysis” this is the thought that every performance test engineers have in their mind (including me). But is this justifiable? Definitely not, it is anything wrong to take additional responsibilities and help team leads or managers to assist them in effort logging, prepare metrics for the client presentation etc. The main issue here is only few testers really aware about metrics funda.

Hence, in this blog post, I am going to list out the Performance Testing Metrics which are aligned with each Performance Testing Life Cycle (PTLC) that needs to be captured and analyzed during the project tenure.

What is the difference between Metrics and Measurement?

Measurement is an entity that defines entity in the form of size, quantity, count, dimension etc. e.g. number of defects found in the system.

Metrics is an entity which derives from measurement. E.g. number of defects per person per hour found in the system.
