Target Code-coverage and Efficiency in APP Automatic Compatibility Testing Based on Code Analysis

With the prosperity of Mobile APPs, developers need to dynamically find the compatibility issues by testing APP on all Android versions and devices, which is costly. This paper finds a systematic test method based on source codes of apps to be tested by identify compatibility-related characteristic codes. We propose an automated tool named “Periph” to search the source code of each app that can eventually generate compact versions and devices set to guide the testing. Through testing 21 apps on 13 Android versions, we find that our proposed tool can greatly reduce the consumption of test resources while only losing little test coverage.
