Practical API Testing with OpenAPI and Citrus Framework

Join Timon Borter’s 30-minute session to level up your OpenAPI testing game using the Citrus Framework and Citrus Simulator. You’ll learn how to auto-generate Citrus actions from your API spec for black-box testing and spin up simulated third-party systems that return realistic, randomized data—all with automatic schema validation on both client and server sides.

This approach not only boosts test quality but also amps up team collaboration by catching issues early in the spec phase. By the time you hit integration, much of the heavy lifting is already done—plus it’s a solid stepping stone toward contract testing with tools like Pact. At PostFinance, we’ve made Citrus + OpenAPI our go-to for seamless CI across services.
