Meta has unveiled the Automated Compliance Hardening (ACH) tool, a mutation-guided, LLM-based test generation system. ACH represents a shift from traditional automated test generation methods by targeting specific faults to enhance software reliability and security. The system allows engineers to define issues using plain text descriptions and automatically generates faults and corresponding tests accordingly. Utilizing LLMs, ACH interprets descriptions, generates faults, and creates tests efficiently. ACH has been implemented across platforms like Facebook, Instagram, and WhatsApp, showing promising results in code hardening and test optimization. Rajkumar S from SAP Labs India praises ACH for revolutionizing software testing and improving code reliability. Meta plans to expand ACHs deployment and further refine its methods for measuring mutant relevance.
