2. 18-549 Team 1: Reflex Project Presentation Test Cases Reflex: glove that allows users to play games Unable to get Wii devkit until May Can control the mouse using Java Test Cases –Performance: response in 20 ms –Respond to each axis movement (x, y, z) –Test flex and force sensors –Check power on/off stages 1/18/2007 2

3. 18-549 Team 1: Reflex Project Presentation 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 1/18/2007 3

4. 18-549 Team 1: Reflex Project Presentation 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 1/18/2007 4

5. 18-549 Team 1: Reflex Project Presentation 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 1/18/2007 5
