API Testing with Postman: Manual and Automated Workflows

Modern software relies heavily on REST APIs, making robust API testing an essential skill for developers and QA engineers alike. Understanding how to manually verify endpoints and automate those checks is key to delivering reliable software. This text-based course guides you from the fundamental principles of HTTP requests to building fully automated API test suites. You will learn how to inspect responses, manage environments, write assertion scripts, and run automated collections as part of a continuous integration pipeline. What you'll learn: - Understand core HTTP concepts, including methods, headers, query parameters, and response status codes. - Configure environments and variables in Postman to easily switch between development, staging, and production setups. - Create automated API tests using JavaScript assertions to validate response structures, response times, and JSON schemas. - Manage complex authentication flows, including Basic Auth, API keys, and modern OAuth 2.0 tokens. - Automate test execution from the command line using Newman and integrate your suites into modern CI/CD pipelines. You will start by learning foundational API concepts and performing basic manual requests, then gradually progress to writing dynamic test scripts, managing environments, and executing command-line automation. This course is designed for beginners, including manual QA testers, aspiring automation engineers, and software developers looking to master API validation. No prior API testing experience is required. Start reading today to build reliable, automated API testing workflows.
