Test of VMF Codecs aims to find errors. This paper proposes an automatic test method of VMF codecs, the method use VMF Data Element Dictionary as the input data. Firstly the test process is designed for pack & unpack functions using legal and illegal test cases, then discusses the test cases suitable for automatic generation, and proposes an automatic test case generation method, the method consists of such steps: design of VMF Data Element Dictionary, message format analysis, generation of message storage struct, generation of message pack & unpack function, generation of legal test case and illegal test case. Lastly this method has been implemented and test experiments are taken, the results show that this method is feasible and effective. © (2014) Trans Tech Publications, Switzerland.

VMF Bit Analysis Tool is a testing and analyzing utility for VMF Codecs, the main function is graphically presenting the message content & code relationship. This paper proposes an automatic VMF Bit Analysis Tool generation method, which uses the VMF Data Element Dictionary as the input data. This method includes such steps: design of VMF Data Element Dictionary, message format analysis, generation of message storage struct, generation of message pack & unpack function and generation of the interface of Analysis Tool. Lastly this method has been implemented and the experiment results show that the tool generated by the method can satisfy the function requirements, also this method can reduce the maintenance time for the tool incorporating the up-to-date information of the VMF Standard. © (2014) Trans Tech Publications, Switzerland.
