The ISTQB® Certified Tester – Testing with Generative AI (CT-GenAI) is a Specialist-level certification that extends the Foundation Level. According to ISTQB®, it "provides testing and quality-engineering professionals with a structured, hands-on path to master how, when, and why to use Large Language Models (LLMs) and other generative-AI techniques across the entire test process – from requirements analysis and test design to automation, reporting, and continuous improvement." It is aimed at testers, test analysts, test engineers, automation engineers and quality-engineering practitioners who already hold foundation-level testing knowledge and now want to apply generative AI responsibly and effectively in daily test work.
