  Unique challenges arise when testing mobile applications due to their
prevailing event-driven nature and complex contextual features (e.g. sensors,
notifications). Current automated input generation approaches for Android apps
are typically not practical for developers to use due to required
instrumentation or platform dependence and generally do not effectively
exercise contextual features. To better support developers in mobile testing
tasks, in this demo we present a novel, automated tool called CrashScope. This
tool explores a given Android app using systematic input generation, according
to several strategies informed by static and dynamic analyses, with the
intrinsic goal of triggering crashes. When a crash is detected, CrashScope
generates an augmented crash report containing screenshots, detailed crash
reproduction steps, the captured exception stack trace, and a fully replayable
script that automatically reproduces the crash on a target device(s). Results
of preliminary studies show that CrashScope is able to uncover about as many
crashes as other state of the art tools, while providing detailed useful crash
reports and test scripts to developers. Website:
