When you first dive into contract testing you’ll hit upon Pact. But Pact is consumer-first. What if you want to do contract-first? There aren’t many tools for that.

This is exactly the challenge we had. So we went looking for a simple pragmatic solution. With just Quarkus, OpenAPI and Git we created a simple setup that works wonders.

In this session I will give a quick tour of our setup.
