Abstract: Diversity in devices, lack of systematic device testing strategy has always led to open questions in the customer’s mind saying “Is the device tested correctly?” Testing of any device integrated with System Under Test (SUT) is certainly different and more complex than testing any traditional software application, as it a comprehensive testing which includes device and the infrastructure of SUT. A systematic device testing approach plays a very important role in getting the device and its supporting traditional software application released in the market with in time ensuring high quality.
