## Description

Everyone loves writing tests, don’t they? How do you write good tests? What tools are available for you to write good tests?
In this session, I will give a whirlwind introduction into the many features of Quarkus that help developers write good tests. I will highlight some of the features of Quarkus, Dev Services and Continuous Testing, which help make testing easier. Additionally, I will live code some tests for common use cases developers encounter, including unit, integration, and “black box” testing. I will discuss techniques such as mocking, spying, and interaction-based testing/verification.
I'll even spend some time showing how IDE-based AI assistants can help!
Once you see how easy TDD really can be there isn't a reason to not do it!
