QAs, as any other human beings make mistakes (read it with Sir David Attenborough voice in your head). Did they learn from it? Yes, perhaps they do but I got a feeling we need quite a few articles like this.
My last article was about top 10 QA mistakes. I did 6 of them because my daughter needed some help with the scissors. I want to finish the series giving you another 5. Oh, wait that’s 11! The title was just an eye-catcher.
