The use case only describes the normal or happy path scenario, where the user performs a successful cash withdrawal. However, it does not consider any alternative or exceptional scenarios, such as invalid card, incorrect PIN, insufficient balance, network failure, etc. These scenarios are important to test the robustness and reliability of the ATM system, and should be included in the use case specification. References = ISTQB Certified Tester Advanced Level Syllabus Test Analyst, Section 2.2.1, Use Case Testing1; ISTQB Advanced Level Test Analyst (CTAL) Exam Study Guide, Section 2.2.1, Use Case Testing2

Exhibit B is the only state transition diagram that matches the text description of Acme’s elevator door rules. It shows that the doors can transition between four states: Opened, Closing, Closed, and Opening. The transitions are triggered by either commands (open or close) or sensors (opened or closed). The diagram also shows that the open command can reverse the closing state, and the close command can reverse the opening state, as specified in the text. The other exhibits do not show the correct transitions or conditions for the elevator door system. References =
