Hello my colleague!
Do you know that people say testers are dilettantes? Sometimes it’s hard to argue. Some people even say we are unprofessionals. You work hard and called unprofessional, wtf? But probably there are some reasons?
As an experienced fellow I’d like to say you that there is not enough to be a good specialist to be a professional. As well as there are no needs to have a broad experience or to be gray-headed to behave as a professional.
Confucius said, “By three ways a tester learns how to behave professionally: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.” I’m going to give you food for thought to make you know which way to prefer in every particular instant; to give you understanding when to imitate and whom; and to make your third way less bitter.
I’ll reveal what is the way of the professional and what is the Cardinal Sin of a tester. Rare book or course covers it.
