Tachometer gauge on a dashboard From Performance Tester to Performance Engineer

Many performance testers think that after a few years of experience, they automatically become performance engineers. However, it isn't that straightforward; the route to becoming performance engineer is a long and continuous journey. This article details the many things performance engineers need to do beyond performance testing, and it gives an outline for steps to take to advance your career.

Continuous operation tests find important bugs, partly as a result of their long operation and partly by increasing the probability of finding statistical bugs. However, CO tests have their own downsides. Mandating a periodic reset or reboot can work around these issues, as well as save time and cost for testing, reproduction, debugging, and fix verification.

In order for performance test results to have value, you should report them in context. There are two main considerations: How do these compare to previous results? And how can we provide early reports on performance while emphasizing that these are preliminary results that may change significantly as we progress? Here are some ideas for responsible reporting.

Gauge with a needle in the green zone, showing good performance 7 Simple Tips for Better Performance Engineering

Rigorous practices to reinforce performance and resilience, and testing continuously for these aspects, are great ways to catch a problem before it starts. And as with many aspects of testing, the quality of the performance practice is much more important than the quantity of tests being executed. Here are seven simple tips to drive an efficient performance and resilience engineering practice.
