1. Novice Testers, Novice Pilots Home-Brewed Testing for a Distributed Flight Simulator Project Mike Meade, Quardev

2. X-Pit Cockpit

3. Overview of the X-Pit System

4. ITA – Locating Existing Bugs • Useful for white or “gray” box testing • Isolate • Target • Amplify

5. Isolate • Isolate the modules • Research and understand module functions • 2n-1 possible locations • 2 modules = 3 combinations • 3 modules = 7 combinations • 4 modules = 15 combinations

6. Target • Target remaining modules • Design tests to exercise possible modules • Ok to exercise eliminated modules • Try to target • 1 module with 1 test • 1 module with multiple tests

7. Amplify • Use general Exploratory Testing techniques • Use data to amplify test results • Exercise base cases • Document test results

8. What we found • Bug was located in the “router” microcontroller • Bug existed since beginning • Load on the system masked the bug • The router never sent the “I2C Stop” signal
