An embedded system requires test process for reality of the system. For this, it is important to test exception handling which programmer developed. Especially, embedded system is required to test input from hardware device and external signal. But, manual test is required much time and low reality. And it is hard to reproduce faulty situation for debugging. In this paper, we propose a new exception handling test criteria for an embedded system. For this criteria, we define exception type and test exception handling using fault injection technique. And we propose generation of test data for occurring exception situation.
