Performance Testing ‘v’ Performance Engineering

The world of software testing has changed hugely over the last 10 years.  Gone are the days of organisations relying on developers manually testing code, now we have automated cloud testing, AI and machine learning, DevOps, CI/CD, business owners demanding speed of change and agility with more and more customers demanding and expecting a perfectly working, delightful experience from any device at any time from anywhere.

The performance of systems and applications has never been under so much scrutiny and pressure as now.  Within the software testing sector, we hear the terms, performance testing and performance engineering with most software consultancies offering solutions for both, however, the messages can sometimes be confusing.

This whitepaper seeks to describe the differences between the two approaches to assist you in making an informed decision on which approach is best for your project, and when to introduce performance testing to obtain maximum value for your business.

Performance Testing ‘v’ Performance Engineering

Unfortunately, there is no ‘one size fits all’ answer when it comes to definitions of Performance Testing or Performance Engineering. However, they can generally be defined by these typical examples:

  • Performance Testing is, in general, a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload.
  • Performance Engineering is a continuous process that is embedded in all phases of the software development cycle – from design to development, and into the end-user experience. This fits well within agile methodologies.

It should be stated that performance testing is predominantly the end validation step, whereas performance engineering covers the overall process which includes performance testing as the final action.
