Course Description

Postman for API Testing: Collections, Environments, and Automated Checks is a practical ebook course in Information Technology focused on software testing skills you can apply immediately to real API projects. You will learn how to use Postman to build reliable requests, validate responses, and turn ad hoc checks into repeatable API tests that support faster releases and fewer regressions.

You will start by setting up a clean workspace and creating core requests that are easy to read and troubleshoot. As you progress, you will organize your API testing work into Postman collections so your test suite stays maintainable as endpoints grow. You will also learn to reuse data with variables and dynamic values, reducing rework and making your tests easier to update when APIs evolve.

To test safely across dev, staging, and production, you will work with Postman environments and learn patterns that keep configuration separated from logic. The course also guides you through common authentication approaches, including API keys, bearer tokens, and OAuth basics, so you can confidently test secured endpoints and handle real-world access requirements.

Automation is a major focus. You will create pre-request scripts to prepare data and sign requests, then build automated checks with Postman test scripts using clear assertions for dependable validation. You will chain requests to model end-to-end workflows, run collections repeatedly to interpret results, and debug failures with a methodical approach that supports continuous testing and CI-friendly execution.

Finally, you will make your work team-ready by applying standards for shared Postman workspaces, enabling reuse and consistent practices across projects.
