API Testing (Postman)

Validate backend logic without a UI. Master Postman Collections, Environments, and automated testing scripts.

API testing is faster and more reliable than UI testing. This course teaches you to use Postman effectively. You will learn to send GET, POST, PUT, and DELETE requests, inspect headers and payloads, and write JavaScript assertions to validate responses automatically. Master Collections to organize requests, Environments to switch between Dev/Prod, and Newman to run your tests in a CI/CD pipeline. Essential for testing microservices.
