The QA has a problem
with one ticket. After tester 1 recognized a problem with the ticket which he couldn´t fix by himself, he asked tester 2 for help. They have been trying to solve the issue for hours but without any result. The 3 green cards in the progress column are already finished by the developers. What should they do next? !
