API Testing in 100 Seconds
#APITesting #APIDevelopment #apitesting
API testing explained in 100 seconds — what it is, the 4 types, how a single test works, and the tools developers use. Perfect for beginners learning REST API testing in 2026.
Your API returns a 200 OK — and your app still crashes. That's exactly what API testing is built to catch. In this video, we walk through API testing for beginners: what it actually is, the anatomy of a single API test, the four types every developer should know (functional, integration, contract, end-to-end), and how teams run these tests in CI.
By the end, you'll understand why every untested endpoint is a 3 a.m. pager waiting to happen — and what to do about it.
What we cover:
• What is API testing (in plain English)
• Anatomy of an API test: request → assertion → result
• The 4 types of API testing every dev should know
• How API testing fits into modern CI/CD
• Tools developers actually use for API testing
