Auto-completing bug reports for android applications

The modern software development landscape has seen a shift in focus toward mobile applications as tablets and smart-phones near ubiquitous adoption. Due to this trend, the complexity of these “apps ” has been increasing, making de-velopment and maintenance challenging. Additionally, cur-rent bug tracking systems are not able to effectively support construction of reports with actionable information that di-rectly lead to a bug’s resolution. To address the need for an improved reporting system, we introduce a novel solution, called FUSION, that helps users auto-complete reproduction steps in bug reports for mobile apps. FUSION links user-provided information to program ar-tifacts extracted through static and dynamic analysis per-formed before testing or release. The approach that FU-SION employs is generalizable to other current mobile soft-ware platforms, and constitutes a new method by which off-device bug reporting can be conducted for mobile software projects. We evaluated FUSION by conducting a study that quantitatively and qualitatively measured the user experi-ence of the system for both reporting and reproducing bugs, as well as the quality of the bug reports it produces. In a study involving 28 participants we applied FUSION to sup-port the maintenance tasks of reporting and reproducing defects on 15 real-world bugs found in 14 open source An-droid apps. Our results demonstrate that FUSION allows for more reliable reproduction of bugs from reports com-pared to traditional bug tracking systems by aiding users in reporting more detailed application-specific information
