Meta's JiTTesting: Disposable Test Probes Catch AI-Generated Code Defects

Meta's JiTTesting generates temporary, diff-specific test probes that run on both parent and new code versions to catch behavioral differences introduced by AI-generated changes, using dual pipelines (Dodgy Diff and Intent-Aware), noise reduction via RubFake and LLM-as-Judge, and human-in-the-loop review, while promoting stable passing tests to the permanent hardening suite.
