Overview

In “API Testing with Postman” we combine fundamentals and practice: you get to know Collections and environments, Pre-request scripts and Assertions with JavaScript, apply what you learn in exercises and receive templates and checklists for your own use.

Good software is not created by testing at the end but by quality assurance throughout the development process. Our test engineering courses teach methodology, tools and automation to testers, developers and test managers. You learn to design test cases systematically, assess risks and run tests reliably in CI/CD pipelines. API Testing with Postman is a one-day workshop: compact theory followed by exercises on a sample application. You work with real tools, create your own test artifacts and take home templates and checklists for your projects.

The course is delivered live – either online in a virtual classroom or on-site in our training rooms in Munich, Salzburg, Berlin, Augsburg, Hanover, Bremen, Stuttgart and Kaiserslautern. We can also run it exclusively for your team.
