A large amount of risk evaluation formulas have been proposed for spectrum-based fault localization (SBFL) in prior studies. A recent study by Xie et al. developed an innovative framework to theoretically analyze the effectiveness of those risk evaluation formulas in SBFL. Xie et al.'s study was based on the assumption that program has only one fault. In other words, they investigated SBFL in the...
A dependence cluster is a set of mutually inter-dependent program elements. Prior studies have found that large dependence clusters are prevalent in software systems. It has been suggested that dependence clusters have potentially harmful effects on software quality. However, little empirical evidence has been provided to support this claim. The study presented in this paper investigates the relationship...
As a promising automatic fault localization technique, Spectrum-Based Fault Localization (SBFL) has been proposed and widely studied for years, in which the effectiveness of risk evaluation formula is one of the most popular research topics. We have developed a framework to support the theoretical analysis of risk evaluation formulas, via subset relations. In this paper, we would like to further justify...
Test case prioritization is an effective technique that helps to increase the rate of fault detection or code coverage in regression testing. However, all existing methods can only prioritize test cases to a single queue. Once there are two or more machines that participate in testing, all exiting techniques are not applicable any more. To extend the prioritization methods to parallel scenario, this...
