Several variance analysis methods that are used in fault localization based on program behaviors were analyzed and compared. None of these methods takes into account the features of object-oriented programs, thus, could not be used accurately in fault localization in object-oriented programs. The present study proposed that when doing variance analysis, object behaviors could be described by using...
In this paper, the framework of finding abnormal behaviors based on patterns was proposed, including preparing data, extracting patterns and finding abnormal behaviors. Then, data preprocessing was introduced in the process of finding patterns, the standard of patterns was defined, the mining algorithm of abnormal behaviors was put forward, and the implementation procedure was described in detail...
Fault localization techniques help programmers find out the locations and the causes of the faults and accelerate the debugging process. The relation between the fault and the failure is usually complicated, making it hard to deduce how a fault causes the failure. Analysis of variance is broadly used in many correlative researches. In this paper, a Bayesian belief network (BBN) for fault reasoning...
