Design and Implementation of a Linux Phone Emulator Supporting Automated Application Testing

This paper presents design and implementation of a Linux phone emulator supporting automated application testing by using UI events and modem events. The emulator has additional functionality that provides an event manager for automated application testing as well as general functionality like off-the-shelf emulators. The event manager can distinguish events generated by emulated software stack from all events generated by host PC. The event manager can record and replay all events of emulation domain through virtual devices such as virtual touchpad, virtual keypad, virtual frame buffer and virtual modem. This technique enables phone makers to test their product efficiently without userpsilas direct input. As the result, we show a demo about emulator interworking with a real phone and describe a promising business scenario of field testing for communication-related functionality. Our experience is provided through this paper to assist an emulator provider to design their product with new features that mobile industry needs today.
