This is the current state of AI agent development: teams are shipping faster than they're testing. Traditional QA doesn't map to LLM-powered systems. Unit tests pass. Integration tests pass. Then your agent loops forever on an edge case your test suite never touched. LLM QA testing is an emerging discipline, and right now almost nobody is doing it properly. This guide is a practical playbook for engineers who need to build a real testing framework for AI agents — not a theoretical overview, but the actual framework, the failure modes, and the tooling that makes it work. Why AI Agent Testing Is Different From Regular Software Testing If you've tried applying standard QA practices to an AI agent, you
