Have you ever felt the urge to increase the amount of testing, thinking it would directly improve product quality? Have you ever been held “accountable” for quality or pressed for time, leaving you feeling helpless? Or perhaps you’ve been asked to justify quality assurance initiatives with numbers?

Our industry is filled with myths: from “quality can be measured” to “more testing means higher quality” and from “QA slows down work” to “testers are responsible for quality”. I believed them all too once, then I started questioning my beliefs when I saw how product quality improved when we reduced code coverage from 70% to 40% — I then realised that quality metrics are only proxy metrics and their correlation should be revisited regularly.

Join me and let's see what dangers all these myths pose to both teams and products, and how they should be debunked and overcome.
