Spectrum-Based Fault Localization for Concurrent Programs

Traditional fault localization techniques are well equipped for identifying faults in sequential programs. Faults in concurrent programs are caused due to interleaving of the threads during run-time. Finding the faults in concurrent programs are more difficult in comparison with sequential programs. In this paper, we have proposed a fault localization framework based on spectrum-based fault localization for concurrent programs to find the faults occurs during execution of multiple threads. The technique finds the most suspicious function or branch for effective fault localization. We have tested the proposed the technique with two different concurrent example programs to check the accuracy of the technique.
