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
• Users presence must be detected from a suitable
  distance
• Test Tester moves into close proximity with the
  device (no more than 50cm), check that users
  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)
