This is the end, my only friend, the end.

The Doors

Something I omitted from the first edition of this book was a concluding chapter. No one commented on its absence, but I thought in the revised edition it would be good to bring things to a close with a short look at future trends for performance testing. Certainly, understanding the end-user experience continues to be an ever-increasing focus of performance testing. The customer is king, and increasing conversions is the goal (at least for ecommerce).

More and more, the EUE is impacted by the plethora of mobile devices available to the consumer. Ironically, this makes IT’s job increasingly difficult as they try to ensure a good EUE across an ever-expanding range of devices, operating systems, and browsers. I predict that the inclusion of on-device automation will become the norm for performance testing, together with the deployment of application performance monitoring software into testing environments (with some overlap into development). The greatly increased insight into and triage capability of software performance that APM provides, along with the relative ease of integration with performance test tooling, makes APM in some form a must-have for most companies.

With the move to continuous integration (CI) driving ever-increasing numbers of releases in shorter and shorter time scales, gaining early insight into performance problems is critical. Performance test tooling, in conjunction with APM, is ...
