In this 30-minute tooling session, Timon Borter shows you how to supercharge your OpenAPI testing using the Citrus Framework and Citrus Simulator. You’ll see how to automatically generate Citrus actions from your OpenAPI spec to test your system under test (SUT) in a pure black-box scenario—and, with the same spec, spin up realistic simulations of third-party services so you can work in full isolation.
Along the way, you’ll learn to generate test clients, build simulations that pump out randomized data, and validate schema conformance on both sides. This approach not only boosts test quality and team collaboration by catching issues early, it’s also a springboard to contract testing with tools like Pact. (Psst—PostFinance swears by this setup for seamless CI across all their services!)
