Fault in terms of Software Engineering is referred to as a bug, an error or a problem which causes a program to crash or generate invalid results. The problem is caused by either incorrect logic or insufficient logic. Fault localization technique plays a very important role in order to determine such errors and to attain the correct outputs. The objective of this work is to assess different fault localization techniques which are in existence. Thus, this can be favorable to the software tester for fault recognition in the program.
