API Testing with Postman - Validating APIs with Postman Requests

This video tutorial covers how to use collections in Postman by adding requests, setting base URLs, and using parameters like nationality filters. It demonstrates setting up tests for API requests using Postman's test tab and the Chai Assertion library. The video also explores advanced testing techniques, such as JSON value checks and sharing tests across collections. The tutorial concludes with a summary of the discussed topics and a preview of the next video, which will delve deeper into sharing code.
