St. Louis Java Users Group March 2024: Creating Realistic JUnit Tests with Testcontainers

Описание: About the Presentation: Sometimes, unit tests with mocked services just aren't enough. We'd like to be able to run repeatable tests against the real thing without fear of corrupting data or affecting others.

With Testcontainers, there is no need for mocks or complicated environment configurations. We can define our target environment in code and then run our tests against ephemeral containers. This tooling has been available to the Java community for some time, but have you realized its capabilities?

We'll enjoy a discussion about unit testing concepts as well as a demonstration of this open-source project created by the folks at AtomicJar, recently acquired by Docker.

About the Presenter: Paul Balogh is a CNCF Ambassador, GoBridge Ambassador, and a Developer Advocate at Grafana Labs. In this role, he encourages developers and testers alike to "shift left," bringing reliability testing earlier in the software development process. He's been a software engineer/architect for over 25 years, programming in various languages and platforms. Working with the open source community around cloud technologies like k6, Kubernetes, and Kafka, among others, keeps him young, as do his interests in punk rock music and playing bass guitar.
