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.

JiTTesting: Just-in-Time Testing for AI-Speed Code Changes

JiTTesting introduces a dual-track testing strategy—permanent hardening tests for regression prevention and temporary catching tests generated on-demand to detect behavioral differences in AI-generated code diffs—using parallel pipelines, automated noise reduction, and human-in-the-loop validation to keep pace with rapid AI-driven development.

Refactoring a Decade-Old Query Optimizer: Architecture, DIFF Fixes, Performance Gains, and Stability Improvements

Tencent engineers completely rewrote a ten‑year‑old query optimizer, shrinking the codebase by 80% and replacing its monolithic thread‑pool with a tRPC‑Fiber DAG scheduler, which cut latency by 28%, reduced startup time to five minutes, saved 40 GB memory, boosted throughput 12%, fixed numerous stability bugs, raised test coverage above 60%, and accelerated new‑feature lead time to under a day.
