Research on Software Interface Testing Technology Based on CAN Bus

This paper firstly introduces the basic information of CAN bus and the general method of CAN testing and points out that application layer protocol is hard to test. Secondly, this paper adapts the method of capturing, analyzing, constructing and sending CAN bus data packet to analyze certain oil system software interface protocol. Then, this paper proves this method can be usde to test the accuracy of the software interface and conduct the further software interface testing.At last,this paper points out the application suggest of this method.
