Who is a tester and how to become one from scratch
We figure out who is suitable for the profession and what a QA specialist needs to be able to do.
Testers, or QA engineers, are people who test how a program or application works. They look for bugs, make sure the program does exactly what it’s intended to do, protect the product from hackers, check how the application works on different devices and on different operating systems.
For those who have not worked as a tester, it seems that it is very simple: pressed all the buttons in a row, found an error, told the developer, and that’s it. In fact, a tester is a complex and creative profession at the intersection of IT, UX design and product management.
But don’t think that testers are just randomly hitting the keys in the hope of finding a bug – this is counterproductive. They have their own methods for identifying program weaknesses and quickly finding bugs.
QA engineers come up with instructions for testing – test cases. At an elementary level, it looks like this: analysts write requirements – what data should be in the input, how they are processed, what should be the result; testers write step-by-step instructions to test the program against these requirements.
