Test Cases Project Concept: Laptop Anti-theft Device Status Update:  Currently working on getting the RFID to communicate with the T-mote (certain voltage issues to sort out)  Desktop interface complete (with password screen) Project Test Cases (Testing the use cases):  Startup (Devices start up without errors)  User moves laptop (Nothing should happen)  User leaves laptop (Arming of device)  Thief moves laptop (Alarm rings)  User returns to laptop (Disarming of device)  Shutdown (Devices shutdown properly)

Performance Tests Degree of movement  Important to distinguish between subtle movements and theft  Test: Various movements around laptop, check correct identification of theft Response time before buzzer sounds  When theft is detected, important to sound buzzer in a timely manner  Test: Move laptop in armed mode, check that buzzer sounds in no more than 500ms (500ms X 100m/10s = 5m) Password security  Password must be resistant to cracking  Test: Look for loopholes in password system (some form of white-box testing) RFID / Disarming range  User’s presence must be detected from a suitable distance  Test: Tester moves into close proximity with the device (no more than 50cm), check that user’s presence is detected

Testing Process Usage of checklists for testing  Useful for checking degree of movement and RFID range  Useful for checking password security Usage of software tools in testing  Software timers for response time calculations (correlate with hardware timers for accurate timings) Testing under heavy conditions  Testing RFID range in area with several RFID readers or tags  Testing with non-user RFID tags

Looking Ahead Anticipated Difficulties  Ambiguity with regards to significance of movement  RFID functionality still a blur, might switch to Zigbee modules for authentication Thankfully, most of our test cases are pretty straightforward  Might include testing with errors to ensure functionality Lessons learnt in testing  As mentioned before, degree of movement test is still rather shady  Difficult for author of code to check correctness (password security)
