Nordic Testing Days 2026

API testing is a core part of modern testing and delivery pipelines, yet it is often misunderstood or introduced too late. This session provides a practical introduction to REST API automation using Python, focusing on what to test, how to structure tests, and how API tests fit into a modern testing infrastructure.The workshop starts with a short overview of API testing fundamentals and common use cases. As a practical part, we'll have a hands-on walkthrough where we write REST API tests covering basic CRUD operations. Attendees will work with Python and the Requests library against a real service with well-documented APIs.I will provide a basic test framework, and we will extend it together by adding and improving tests during the session. The workshop requires Python 3.13+ installed and basic familiarity with Python to read and write test code.
