Towards A Contextual and Scalable Automated-testing Service for Mobile Apps

Li Lyna Zhang, Chieh-Jan Mike Liang, Wei Zhang, Enhong Chen
2017 Proceedings of the 18th International Workshop on Mobile Computing Systems and Applications - HotMobile '17  
In fact, this is a challenging problem that current emulator-based or device-based testing services cannot properly or scalably address.  ...  However, we argue that these existing services do not sufficiently bring real-world contexts into app testing, which reduces the visibility into how an unreleased app would perform in the wild.  ...  Presenting an unified view requires RainDrops to aggregate logs from these two heterogeneous sources, as described in §3.2. Fig 2 illus trates steps of offloading.  ...
