Fault Localization Method of Software Defects based on Dependencies Analysis of Program Structure

Software defects are the major risks of system stable operation. Its error localization technology of automation is one of the key research content for trust computing and software assurance. In this paper, we have proposed a new model, which integrates the current methods by analyzing the program structure. We put forward a new automated fault localization method, this method without the degree loss of automation, at the same time, particle size down to basic positioning code statements, makes the position more accurately. We have designed an experiment to examine the effectiveness of CPD base on SIR. And we proved that the CPD is more effective.
