Our work differs from these projects in that it uses inconsistencies
in apps to identify problems in the app development
frameworks. While our work has primarily targeted APIs used
to support application logic, future work on testing mobile
apps created using Web-based frameworks (e.g., [1, 3, 7])
can possibly use the techniques from X-PERT and FMAP to
identify inconsistencies in the way UI elements are displayed
across platforms.
