API Testing

Build a Postman collection and turn it into a real test suite — all through Postman's Agent Mode. In this first module you'll create the workspace and collection you'll test, then prompt Agent Mode to write your first assertions: the status line, the response headers, and the shape and values of the response body. Let Agent Mode do the typing, but never approve a test you can't explain. You'll practice against the Movies API, a free, public REST API with no authentication.

Take your Movies API test suite beyond the happy path — all through Postman's Agent Mode. This module is fully self-contained: it recreates the workspace and collection from scratch (with a baseline of status, header, and body tests), then goes deeper — negative tests for missing resources and invalid input, workflow tests that chain requests with variables, a response-time budget, and finally running the whole suite with the Collection Runner and auditing your own coverage. Let Agent Mode do the typing, but never approve a test you can't explain. You'll practice against the Movies API, a free, public REST API with no authentication.
