One of the key tools that performance engineers have at their disposal is the Performance Budget: it helps us—or, more importantly, our clients—ensure that any performance-focused work is monitored and maintained after we’ve gone. By establishing an acceptable threshold, be that based on RUM data, bundle analysis, image weight, milestone timings, or any other suitable metric, we can be sure that new or unrelated bodies of work do not have a detrimental impact on the performance of our site.

According to the ISTQB glossary, Regression is “degradation in the quality of a component or system due to a change”. And, Regression Testing is “a type of change-related testing to detect whether defects have been introduced or uncovered in unchanged areas of the software.”. Hence, whenever there is a change in the code, we need to ensure that the previously intact and working code is still working and that the changed code has not impacted the working code in a negative way.
