بچه‌های مهندسی متا یه ابزار جالب برای پیدا کردن باگ معرفی کردن به اسم JiTTests که بعد از یک سال تحقیق، حالا وارد زیرساخت‌های اصلی این شرکت شده

🧠 Most AI bug-catching tools review your code the way a human reviewer would, only faster. What if the AI wrote a test that proved the bug instead? That’s Catching Just-in-Time Tests (JiTTests) — a novel approach where LLMs generate executable tests designed to fail, surfacing behavioral changes in a code change before it lands. After a year of research, it’s now part of Meta’s infrastructure. ✅ 589 engineers have engaged with it, reporting a 60% true-positive rate 📈 In the first half of 2026, it helped catch 74 privacy SEVs at the diff stage, lowering overall privacy SEV occurrence by 20% 🔗 Read how it works: https://engineering.fb.com/2026/10/29/security/catching-bugs-before-they-land-jittestings-human-on-the-loop-approach-at-full-scale/ 📄 Read our FSE 2026 paper, “Just-in-Time Catching Test Generation at Meta”: https://arxiv.org/pdf/2601.22832 #AI #SoftwareEngineering #SoftwareTesting #DeveloperTools #Engineering
