JUnit 5: More than just a Testing Framework for Java

JUnit 5: More than just a Testing Framework for Java

Over the last decade a lot has happened in the world of Java and testing, but JUnit 4 hasn’t kept up. Now JUnit 5 is here to help shape the future of testing on the JVM with a focus on Java 8 language features, extensibility, and a modern programming API for testing in Java. Moreover, JUnit isn’t just a Java testing framework anymore. Third parties are already developing test engines for Scala, Groovy, Kotlin, etc. that run on the new JUnit Platform. In this session, core JUnit 5 committer Marc Philipp will take the audience on an example-driven tour of the new Jupiter programming model and show how to migrate existing JUnit 4 based tests. Then, we will discuss the inspiration for JUnit 5, look more closely at its architecture, and discuss compatibility with JUnit 4. Next, we will explore the Jupiter extension model, learn about the extension points it provides, and see how custom extensions for conditional tests, method parameter resolution, lifecycle callbacks, etc. are authored and registered. To round off the session, we will look at the roadmap of what’s still to come.
