  As the popularity of mobile smart devices continues to climb the complexity
of "apps" continues to increase, making the development and maintenance process
challenging. Current bug tracking systems lack key features to effectively
support construction of reports with actionable information that directly lead
to a bug's resolution. In this demo we present the implementation of a novel
bug reporting system, called Fusion, that facilitates users including
reproduction steps in bug reports for mobile apps. Fusion links user-provided
information to program artifacts extracted through static and dynamic analysis
performed before testing or release. Results of preliminary studies demonstrate
that Fusion both effectively facilitates reporting and allows for more reliable
reproduction of bugs from reports compared to traditional issue tracking
systems by presenting more detailed contextual app information. Tool website:
