Towards black box testing of android apps

Many state-of-art mobile application testing frameworks (e.g., Dynodroid, Evo Droid) enjoy Emma or other code coverage libraries to measure the coverage achieved. The underlying assumption for these frameworks is availability of the app source code. Yet, application markets and security researchers face the need to test third-party mobile applications in the absence of the source code. There exists a number of frameworks both for manual and automated test generation that address this challenge. However, these frameworks often do not provide any statistics on the code coverage achieved, or provide coarse-grained ones like a number of activities or methods covered. At the same time, given two test reports generated by different frameworks, there is no way to understand which one achieved better coverage if the reported metrics were different (or no coverage results were provided). To address these issues we designed a framework called BBox Tester that is able to generate code coverage re...
