Module localization 

Advanced Fault Localization Module (BH-16 to BH-20)

Implements research-based fault localization techniques:

• BH-16: Mutation-Based Fault Localization (MBFL)
• BH-17: Causal Fault Localization
• BH-18: Predictive Mutation Testing
• BH-19: Multi-Channel Fault Localization
• BH-20: Semantic Crash Bucketing
