Software is a major component of any computer system. To maintain the quality of software, early fault localization is necessary. Many different fault-localization methods have been used by researchers. Ideally, methods for fault-localization are used in such a way that one is able to detect as many faults as possible using the least resources. But, in general, it is hard to predict a test suite's fault-localization capability. This paper gives a review of the previous studies that are related to software fault-localization methods. It reviews various journal and conference papers on localization of faults and various methods for localization of faults proposed in the literature.
