Which statements about use-case testing are most accurate?

The most accurate statements regarding use-case testing focus on the characteristics and components of use-cases and the roles of actors within that context. One key aspect of use-case testing is the representation of interactions and relationships, making it important to clarify what each statement conveys.

A use-case diagram indeed illustrates how users (actors) interact with the system, but the role of an actor is not limited to human users; it can also include other systems or entities interacting with the application. A use-case, on the other hand, is not commonly used as a basis for unit testing, which tends to focus on smaller units of code rather than high-level interactions.

The description of a use-case as a process that outlines interactions is accurate; it serves as a foundation for understanding what the system should do from the perspective of various stakeholders. Therefore, statements about actors and their representation in use-case scenarios emphasize their diversity and the functionality of use-cases in defining user interactions.

The statement about use-cases being the most common basis for unit testing does not accurately reflect standard practices in software testing, as unit tests typically derive from code-level design rather than high-level user interactions described in use-cases. Thus, focusing on the structural components and interaction dynamics presented in use-cases
