Google AI Releases Auto-Diagnose: A Large Language Model (LLM)-Based System to Diagnose Integration Test Failures at Scale

Google introduced Auto-Diagnose, a Gemini-based tool for finding the root cause of integration test failures.

It reads integration test and component logs, then posts a likely diagnosis directly in code review.

In evaluation, it identified the correct cause in 90.14% of 71 real failures and is already running at large scale.

The tool aims to cut debugging time in large distributed systems and reduce time to fix by automating root-cause analysis.
