Section C — Functional Testing (20 points) 7. (8 pts) Design 6 black-box test cases covering core functionality. For each case include: test objective, preconditions, input, expected result, and priority (High/Medium/Low). 8. (6 pts) Design 4 boundary and edge-case tests (e.g., large inputs, empty values, concurrency). Include expected behavior and rationale. 9. (6 pts) Describe an automated test strategy (tools, frameworks, CI integration, test data management) to achieve 80%+ regression coverage for the core modules. Include one concrete example test snippet in pseudocode or a short code block showing how you’d assert a critical behavior.
The standby LED light will begin flashing rapidly (usually alternating red and green). the USB drive and power off the unit
Understanding the hardware limits of your board prevents you from flashing incompatible software files, which can permanently brick the device. TSUMV59XU-Z1 Flash IC: 4MB / 8MB (Typically 25Q32 or 25Q64)
