kasutusjuhust

A kasutusjuhus, or use case, is a description of how a user will interact with a system to achieve a specific goal. It details the sequence of actions taken by the user and the system's responses. Kasutusjuhud are fundamental in software development and system design, helping to understand user needs and define system functionality.

Each kasutusjuhus typically includes a name, a brief description, preconditions, a basic flow of events, alternative flows, and postconditions. The basic flow outlines the most common path through the interaction. Alternative flows describe variations or exceptions to the basic flow. Preconditions specify the state the system must be in before the kasutusjuhus can begin, and postconditions describe the system's state after the kasutusjuhus is successfully completed.

Kasutusjuhud are valuable for communication between stakeholders, including users, developers, and testers. They help ensure that the system being built meets the intended requirements and provides a clear understanding of expected behavior. By focusing on user goals and interactions, kasutusjuhud contribute to creating user-friendly and effective systems. They can be represented in various formats, from simple text descriptions to more detailed diagrams.
