Automation testing is very popular now, but manual testing still exists. When I interviewing people, they often told me that, they are manual testers. I like to ask, do they try to do it faster and how. I expected to hear something about test design techniques. But what else you can do to test fast, because the final result of testing is not just words “I’ve tested it”. Test cases are often the final results of testing. I would like to tell about test case optimization when they are needed and could you exclude them from your process or not.
