Postman collections provide a structured way to organize, document, and automate API requests for development and testing workflows. This section guides you through creating collections with folder hierarchies, parameterized requests using variables, pre-request and test scripts with JavaScript, chai assertion patterns, workflow branching via setNextRequest, data-driven testing with CSV and JSON files, and continuous integration using Newman. Build a complete Postman project for real-world API testing.
