Abstract
We demo VALERA, a Versatile-yet-lightweight Record- and-replay tool for Android. Record-and-replay is useful across the Android development lifecycle, from bug reproducing to systematic testing. VALERA uses a novel technique named sensor-oriented replay (recording and replay- ing sensor and network input, event schedules, and inter-app communication via intents) to achieve high accuracy and low overhead. VALERA can be used as an effective replay tool on both real phones and emulators. Evaluation on more than 50 popular Android apps shows that VALERA’s performance overhead for either record or replay is just 1%. We demonstrate how VALERA can be used in many development scenarios: bug reproducing, regression testing, event- driven race reproduction and verification, mutation testing via fuzzy replay, and cross-app testing.
