In many projects, JUnit is still used the way it was years ago — without taking advantage of the relevant innovations introduced in recent releases. Yet JUnit 5 has evolved significantly since its initial release: over eight years and twelve major updates, it has become a powerful, flexible, and extensible testing platform.
The JUnit 5 Revolution: First-Hand Insights
At JCON EUROPE 2025, developers will have the opportunity to not only discover the latest features of JUnit 5 but also to apply them directly. In the two-hour hands-on session “Catching up with JUnit 5“, two key members of the JUnit team will guide participants through the most important developments.
Meet the Experts: Core Committer and Oracle Engineer Live
- Marc Philipp: A Longtime JUnit core committer, team lead, and key figure for JUnit 5’s existence, will provide deep insights into the framework’s design and evolution.
- Christian Stein: JDK Tooling developer at Oracle and an active contributor to JUnit and Maven, will guide participants through practical, real-world examples.
Instead of traditional lectures, attendees will work directly in their IDEs on real test scenarios, supported by immediate feedback from the experts.
Focus Topics
Participants can expect a compact overview of essential techniques and best practices, including:
- How the test lifecycle really works – and how to control it.
- How to use tags, timeouts, order, and display names effectively.
- The full potential of parameterized tests with custom arguments.
- How to tap into (or extend!) the JUnit Jupiter extension model.
New Approaches to Modern Testing
This hands-on session offers much more than just an update on JUnit features. By the end of this workshop, you won’t just be up to date – you’ll be ahead of the curve, with a toolkit of techniques you can bring straight back to your team and projects.
Developers looking to move beyond traditional unit testing methods will gain valuable insights into how JUnit 5 enables more powerful and adaptable test structures. To future-proof their testing strategies, participants have a unique opportunity to gain direct expertise from the JUnit insiders.
