Abstract: A technique of multiple fault localization based on conditioned execution slicing spectrum  considers program dependency and reduces the problem which the efficiency of the technology will decrease with the increase of the number of faults in the program. But the technology is affected by the fault-independent statement and is validated in a particular program. Therefore, Conditioned Classification Execution Slicing Spectrum-based Software Fault Localization（CCESS-SFL） is proposed, The technology improves and classifies predicate conditions in CESS-MFL technology. Firstly, the conditional feature set is determined according to the predicate conditions and the fault-related conditioned execution slicing, the conditional classification is performed according to the conditional feature set to obtain the conditional classification execution slicing spectrum, then, the suspiciousness of the element is calculated, finally the suspiciousness report is generated. CCESS-SFL technology has been validated in seven Siemens suites. It is superior to the current popular Tarantula, Jaccard, Ochiai and CESS-MFL technology and can reduce the impact of fault-independent statements.
