Research on Automatic Test Method of VMF Codecs

Abstract

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.
