Software fault localization based on data chain

Data flow related faults are very common in program and difficult to locate. This paper proposes a data chain model that takes account of variable change and dependencies information, and puts forward a fault location approach based on the data chain model. The main research of this paper is verified by experiments. The experimental results show that the proposed approach achieves better results comparing with other fault location approaches such as DU-pair, program slice, PPDG, and statement coverage.
