N. Suguna, R M. Chandrasekaran . Fault Localization using Probabilistic Program Dependence Graph. International Journal of Computer Applications. 66, 21 ( March 2013), 27-33. DOI=10.5120/11242-6443
Fault localization is an expensive technique in software debugging. Program dependence graphs are used for testing, debugging and maintenance applications in software engineering. Program dependence graphs (PDG) are used to build a probabilistic graphical model of program behavior. In this paper we proposed a model based fault localization technique using probabilistic program dependence (PPDG). This work presents algorithm for constructing PPDGs and PPDGs based fault localization. Our experimental result shows that proposed PPDG based fault localization method performs better than existing testing based fault localization (TBFL) method for DotNet programs. Our results also indicate that the probabilistic approach is efficient for fault localization.
