Performance: response in 20 ms
Respond to each axis movement (x, y, z)
Test flex and force sensors
Check power on/off stages

Performance Tests
• Metric is real-time response: 20 ms
• The amount of time before humans
notice lag
• Plan
– Grab current time and send test message
– Round trip test message to all parts
– At end read current time and compare to
time before sending the test message

Testing Process
• #define for performance testing
• Physical movement by user for axial
testing
• One user, but can change tester to see
if works for different people
• Test automation difficult, but not too
many parts to test

Looking Ahead
• Getting real-time performance data is
difficult
• Exception testing is risky (delicate
equipment)
• Failure recovery is dependent on code
not written by us
• Test automation difficult, but not too
many parts to test
• Ambition is good, Reality is better
