API Testing and Automation with Postman

In modern software development, ensuring that application programming interfaces (APIs) are reliable, secure, and fast is a critical skill. Postman is the industry-standard tool that simplifies the process of sending requests, verifying responses, and automating tests. This course guides you from the absolute basics of HTTP requests to building robust, automated test suites. You will gain the confidence to validate API behavior, manage complex environments, and integrate your tests into automated workflows. What you'll learn: - Understand foundational REST API concepts, HTTP methods, and status codes. - Configure Postman collections, variables, and environments to manage dynamic API data securely. - Write automated test scripts in Postman using JavaScript to validate response payloads and headers. - Perform data-driven testing using external data files to run scenarios at scale. - Handle complex authentication methods, including Basic Auth and OAuth 2.0 flows. - Execute collection runs from the command line using Newman and integrate tests into CI/CD pipelines. The course begins with core API terminology and basic request configuration before moving into scripting, environment management, and automated test execution. You will read clear explanations and study practical code examples designed to build your testing skills step-by-step. This course is designed for beginners, including QA engineers, developers, and product managers who want to learn API testing from scratch without prior automation experience.
