Application of Fault Location with Hot Path and Program Slicing

Regression testing means testing the modified software.Improving the efficiency of error analysis of regression testing,based on the current thinking in the heat path in the application of program analysis,combined with program slicing method,proposed an efficient method for regression testing.Firstly finding out the method path frequencies of execution in the program-level execution,application of combined application Dslice slicing algorithm for regression testing,the procedure known to debug errors,more accurately locate the method error level.The results show that the path through the heat combined with the proceeds of program slicing algorithm can improve the efficiency of regression testing,error analysis.
