DroidMate-2: A Platform for Android Test Generation

Android applications (apps) represent an ever increasing portion of the software market. Automated test input generators are the state of the art for testing and security analysis. We introduceDroidMate-2 (DM-2), a platform to easily assist both developers and researchers to customize, develop and test new test generators. DM-2 can be used without app instrumentation or operating system modifications, as a test generator on real devices and emulators for app testing or regression testing. Additionally, it provides sensitive resource monitoring or blocking capabilities through a lightweight app instrumentation, out-of-the-box statement coverage measurement through a fully-fledged app instrumentation and native experiment reproducibility. In our experiments we compared DM-2 against Droid-Bot, a state-of-the-art test generator by measuring statement coverage. Our results show that DM-2 reached 96% of its peak coverage in less than 2/3 of the time needed by Droid-Bot, allowing for better and more efficient tests. On short runs (5 minutes) DM-2 outperformed Droid-Bot by 7% while in longer runs (1 hour) this difference increases to 8%. ACM DL Artifact: https://www.doi.org/10.1145/3264864.
