Its like a spectrum based fault localization has reach its picks in one aspect of solving fault location.
Few of the SBFL metrics are actually effective and the only problem is that when there are too many coincidental spectra, these metrics would have many ties during ranking and that is why a developer would have to go through many tie ranks before locating the fault in a program.
What are the other information that can be collected during program run time that can help to debug using SBFL method of fault localization?
