Migration from JUnit 4 to JUnit 5

JUnit 5 does not support JUnit 4 features, such as Rules and Runners, natively. Nevertheless, JUnit 5 provides a gentle migration path via the JUnit Vintage test engine, which allows us to execute legacy test cases (including JUnit 4 but also JUnit 3) on the top of the JUnit Platform.

The following table can be used to summarize the main differences between JUnit 4 and 5:

Feature	JUnit 4	JUnit 5
Annotations package	org.junit	org.junit.jupiter.api
Declaring a test	@Test	@Test
Setup for all tests	@BeforeClass	@BeforeAll
Setup per test	@Before	@BeforeEach
Tear down per test	@After	@AfterEach
Tear down for all tests	@AfterClass	@AfterAll
Tagging and filtering	@Category	@Tag
Disable a test method or class	@Ignore	@Disabled
Nested tests	NA	@Nested
Repeated test	Using...
