Suppose bugs were reported in first testcycle. Now all the bugs have been fixed and are in resolved state for second testcycle. When second testcycle will start, bug verification of these bugs will be done by testers. They try to reproduce those bugs on their mobile and if they are fixed then mark those bugs as closed. If bug is not fixed then they mark it as “Not Fixed”. If tester is not able to verify the issue, he marks it as “Could not verify”.
