Test case

A test case in software engineering is a set of conditions or variables under which a tester will determine whether an application or software system is working correctly. The mechanism for determining whether a software program or system has passed or failed such a test is known as a test oracle. In some settings, an oracle could be a requirement or use case, while in others it could be a heuristic. It may take many test cases to determine that a software program or system is considered sufficiently scrutinized to be released. Test cases are often referred to as test scripts, particularly when written. Written test cases are usually collected into test suites. We can copy all the steps from USE Case and check if our desired output comes out.. Therefore its easy to use. Most of test cases are based on use case.. If no use case, then we have to create test case, based on functional requirement. Suppose. In perfect world, we have use cases and then test case has #, description and test steps.. (similar as use case) and then desired output.. Say test case failed or passed.
