This December we'll be holding our final event of the year virtually on Wednesday 13th December wirg Holly Cummins presenting **Tame Microservices with Contract Testing.**

**Presentation Synopsis:**
Every time you change one microservice, the others break. But you had unit tests! What’s going on?

Unit tests aren’t enough to give system-level confidence, even with a microservices architecture.
What’s the solution? Integration testing is annoyingly expensive, flaky, and fries your laptop. Remocal development environments are complex to manage. Testing in production is important, but the feedback loop is longer, so it’s not a substitute for local inner-loop testing.

Enter contract tests.

Contract tests combine the lightness of unit tests with the confidence of integration tests, and should be part of your development toolkit.

This session will explain how contract tests can fit into a modern workflow, and demo one popular contract testing framework, Pact. The demos will be run on Quarkus, but Pact runs on all Java frameworks, and has libraries for almost all of the popular programming languages.
