Coverage-based fault localization techniques are effective to support program debugging. However, these techniques assess the suspiciousness of program entities individually. Such calculation oversimplifies executions and cannot reflect execution contexts. In this paper, the authors use control flow paths to analyze the execution context, quantify edge profiles to assess how each block contributes to failures and propose the context-aware fault localization approach FP. They use the edge profile to represent the passed and failed executions, calculate the coverage statistics and edge suspiciousness scores, and then by contrasting edge suspiciousness scores of blocks covered by a failed execution, they propose fault proneness to evaluate how each block contributes to the failure.
