OpenAI Codex Testing and Debugging

Codex can help developers move through coding tasks quickly, but its work still needs to be inspected, tested, and followed up before it is accepted. In this course, OpenAI Codex Testing and Debugging, you'll gain the ability to inspect, troubleshoot, and validate Codex-assisted work. First, you'll explore Codex automations, session transcripts, stuck states, and inline review comments. Next, you'll discover how to use Codex Computer Use to run structured QA passes and turn findings into reviewable follow-up work. Finally, you'll learn how to apply the OpenAI Evals API to check output shape and prompt behavior after a Codex-driven change. When you're finished with this course, you'll have the skills and knowledge of Codex testing and debugging needed to review automation output, recover from common issues, and validate AI-assisted code changes.
