Firstly, we propose a method in theory about how to increase the speed-up ratio in parallel test generation based on fault partitioning. Based on the method a new fault partitioning approach - Backward Fault Partitioning based on Output fan-in Cones (BFPOC) - is presented, which combines the relevant fault identification and shortest path sensitization. Then, BFPOC is compared via experiments with the approach of Toward Fault Partitioning based on Input fan-out Cones (TFPIC) proposed by Banejee and the widely used method - Equal Distance Partitioning of Fault Sequence (EDPFS) respectively. The results show that in large-scale parallel processing environment, BOPOC can obtain higher speed-up ratio than the other two approaches.
