käyttötapaustestausta

Käyttötapaustestausta, or use case testing, is a software testing technique that verifies a system's compliance with its specified use cases. A use case describes a sequence of actions a user performs to achieve a specific goal with the system. In use case testing, these described scenarios are translated into test cases. The primary objective is to ensure that the system behaves as expected from the end-user's perspective, covering both typical and exceptional flows of events.

The process typically involves identifying all relevant use cases, then designing test cases that represent these use cases. Each test case will include preconditions, a sequence of steps, and expected outcomes. The execution of these test cases involves following the defined steps and comparing the actual results with the expected results. Discrepancies indicate defects or deviations from the intended functionality.

Use case testing is beneficial because it focuses on how users will interact with the system, ensuring that the most important functionalities are tested thoroughly. It helps in identifying functional errors and usability issues. This technique is particularly useful for validating the business requirements of the software and ensuring it meets the needs of its intended audience. It provides a structured approach to testing, making it easier to track progress and coverage.
