FaultGene: LLM-Assisted Fault-Augmented Test Generation for Hardware-in-the-Loop Validation of Autonomous Driving Systems

FaultGene is an LLM-assisted framework that automatically generates executable fault‑augmented tests for hardware‑in‑the‑loop validation of autonomous driving systems. It takes a baseline Scenic/CARLA scenario and a structured fault specification, then produces fault‑augmented test cases that reflect HIL‑level fault injection effects. The system refines candidates offline using semantic‑consistency checks and execution‑level feedback, enabling high‑quality test generation at deployment time without manual engineering or repeated refinement loops.
