We can use the JUnit Vintage test engine to run JUnit 4 tests with JUnit 5. All classes specific to JUnit 4 are located in org.junit package. All classes specific to JUnit 5 are located in the org.junit.jupiter package.
Accordingly, @Test (JUnit 4 & JUnit 5): The @Test annotation is common for JUnit 4 as well as JUnit 5. The annotated methods represent the test cases in the class. There could be multiple methods each annotated with @Test in a JUnit class. This implies that a class may have multiple test cases. Moreover, Migration from JUnit 4 to JUnit 5 could be a slow and steady process. At this point in our project, we have some tests fully migrated to JUnit 5, some partially migrated but using some JUnit 4 features, and potentially there may be some classic JUnit 4 (or even JUnit 3) tests running as they are. Similarly, The JUnitPlatform runner is a JUnit 4 based Runner which enables you to run any test whose programming model is supported on the JUnit Platform in a JUnit 4 environment — for example, a JUnit Jupiter test class. Likewise, JUnit Jupiter is the combination of the new programming model and extension model for writing tests and extensions in JUnit 5. The Jupiter sub-project provides a TestEngine for running Jupiter based tests on the platform. JUnit Vintage provides a TestEngine for running JUnit 3 and JUnit 4 based tests on the platform.
