Non-parametric statistical fault localization [PDF]

open access: yesJournal of Systems and Software, 2011
Abstract: Fault localization is a major activity in program debugging. To automate this time-consuming task, many existing fault-localization techniques compare passed executions and failed executions, and suggest suspicious program elements, such as predicates or statements, to facilitate the identification of faults.
