Abstract: Although the technique of fault location and automated program repair have been developed in recent years,programmers still need to spend a lot of time and effort on repairing．Most developers still work with traditional debugging techniques such as breakpoints．The research results of fault location have not been applied in practical work of repairing．In recent years,the technique of automated program repair has been concerned and developed．In the work of automated software repair,using the technique of fault location to locate the bugs is a necessary activity and the accuracy of localization affects the generation of patches,which has a great impact on the effect of repair．GenProg-FL tool can use different techniques of fault location to repair programs．Also,GenProg-FL can be used to evaluate the effectiveness of fault location techniques．

Key words: Fault location,Automated program repair,GenProg-FL
