testijuhtud

Testijuhtud, often translated as test cases or test scenarios, are a fundamental element in software testing. They represent a set of actions, conditions, and expected results that are performed to verify a specific functionality or feature of a software application. The primary purpose of a test case is to determine whether the software under test behaves as expected under various circumstances.

Each test case typically includes a unique identifier, a description of the functionality being tested, preconditions that must be met before execution, a sequence of steps to follow, input data, and the expected outcome. The expected outcome is crucial as it serves as the benchmark against which the actual result observed during testing is compared. If the actual result matches the expected result, the test case is considered passed. Otherwise, it is marked as failed, indicating a potential defect or bug in the software.

Test cases can be designed at different levels of granularity, from unit tests that focus on individual components to system tests that evaluate the entire integrated system. They are developed based on requirements, specifications, user stories, and even potential risks and vulnerabilities. Well-written test cases are clear, concise, and unambiguous, ensuring that they can be consistently executed by different testers. They play a vital role in ensuring software quality, reducing the likelihood of defects reaching end-users, and providing confidence in the stability and reliability of the software.
