Likewise, to run the tests with Gradle we also need to enable JUnit Platform in tests. We have to add all the dependencies to pom.xml: In addition to this, to run the tests with Maven we also need the Surefire plugin. Vintage test engine to run JUnit 4 tests.JUnit Jupiter to write and run JUnit 5 tests.In order to run both JUnit 4 and JUnit 5 tests we need:

LetвЂ™s see what we need to do to run existing test on the new platform. Next we will take a deeper dive into each of these steps. This step could take more time than the others. JUnit 5 has a single extension model instead of runners and rules. Replace runners and rules with extensions Method argument order is different in some cases. Some new ones replace the old ones, and function a little different.ДЄssertions and assumptions have been moved to new classes. Some JUnit 5 annotations are the same as JUnit 4. JUnit 5 has additional dependencies for migration support and JUnit Vintage engine. The following table summarizes the key migration steps in migrating from JUnit 4 to JUnit 5. Because of this, we can plan the migration gradually. If both JUnit 4 and JUnit 5 are in the classpath, there will be no conflicts.ДЄs a result, we can keep our previously implemented JUnit 4 tests together with the JUnit 5 tests until we finalize the migration. All classes specific to JUnit 5 are located in the package. We can use the JUnit Vintage test engine to run JUnit 4 tests with JUnit 5.ДЄll classes specific to JUnit 4 are located in org.junit package. JUnit provides a gradual migration path with the help of JUnit Vintage test engine. JUnit 5 adds better support for parameterized tests and native support for nested tests along with some other new features. This has inspired third-party developers to create specialized runners for these situations. JUnit 4 never advanced beyond Java 7 missing out on Java 8 features.ДЄlso, JUnit 4 has shortcomings in parameterized tests and lacks nested tests. In JUnit 5 this is finally possible by registering multiple extensions.ДЇurthermore, JUnit 5 utilizes Java 8 features like lambdas for lazy evaluation. SpringJUnit4ClassRunner and Parameterized at the same time). One of the biggest flaws of JUnit 4 is that it does not support multiple runners (so you cannot use e.g. Here are some advantages of JUnit 5 over JUnit 4: Finally, JUnit Vintage allows us to run JUnit 4 tests with JUnit 5.JUnit Jupiter is the new API for writing tests and extensions in JUnit 5.The basis, JUnit Platform provides build plugins, and an API for writing test engines.JUnit has been split into three different sub-projects: The key point of the new architecture is to separate concerns between writing tests, extensions and tools. JUnit 5 has a modular design unlike the previous versions. This article is part of the JUnit 5 Tutorial.

We will see how to run existing tests along with the new version, and what changes we have to do to migrate the code. In this article, we will take a look at the steps required for migrating from JUnit 4 to JUnit 5.
