Stop Writing API Tests Manually - Use ChatGPT Instead
Most developers write API test cases by hand — one endpoint at a time, one scenario at a time. That process is slow, inconsistent, and completely unnecessary. In this tutorial, you'll learn how to use ChatGPT to generate structured API test cases in minutes, then validate and refine them inside Postman. This video is built for junior to mid-level QA engineers and developers who are tired of starting from a blank collection and want a faster, smarter starting point. Every demo uses a real API workflow.
These skills matter because speed and coverage are both expectations now. Knowing how to prompt ChatGPT for specific test scenarios, catch its hallucinations before they waste your time, and iterate with real API feedback puts you ahead of every QA engineer still writing test cases from scratch.
