Research on code pattern automata-based code error pattern automatic detection technique

Nowadays, many defects, e.g., obscure error generation-scenario and lacking of formalization which is the basis for the automatic error detection, exist in field of code error research. Furthermore, the automation of error detection will greatly affect the quality and efficiency of software testing. Therefore, more deeply research on code errors need to be done. At first, this paper presents the definition of code error pattern based on definition of pattern. Secondly, it investigates the formalization description of code error pattern. Then, it studies the automatic error pattern detecting technique based on non-determinate finite state automata and treats the matching technique of error pattern as the key problem. Finally, some case studies are given. The preliminary results show the rationality of code error pattern definition and the effectiveness of error pattern formalization description and error pattern matching technique.
