The scenario design test case is mainly used in the event trigger process. When an event is triggered, a corresponding scenario flow is formed, with different event triggers, different sequences, and different processing results, to form a series

Now that RUP is at its zenith, demand analysis is the first step and can be seen as a prerequisite for advanced system analysts, so if you use object-oriented analysis techniques to describe the requirements.
In a demand analysis process, there are project descriptions, risk analysis, use case diagrams, and descriptions, which are part of the project recommendations.

The use case diagram is mainly used to illustrate the main event process of the system. It is mainly used to describe the customer's needs, that is, the user wants the system to complete certain functional actions, the general understanding of use cases is the functional module of the software, so it is the starting point of the design system analysis phase.
