Is there any special configuration to use SpringRunner with junit5?

Question

My micro-service project based on spring-boot framework and all my unit test running with spring runner.

@RunWith(SpringRunner.class)

adding this annotations, imports the following library:

import org.springframework.test.context.junit4.SpringRunner;

How can I set my test classes to run with junit5 ?

Answer 1

Remove JUnit4 from your build Path.

For example :

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
@TestPropertySource(locations = "classpath:application-local.properties")
public class MyTest {
    @Before
    public void setUp() {
        ...
    }

    @Test
    public void testMethod() {
        Assert.assertTrue(...);
    }
}

will become

@SpringBootTest(classes = Application.class)
@TestPropertySource(locations = "classpath:application-local.properties")
public class MyTest {
    @BeforeEach
    public void setUp() {
        ...
    }
    @Test
    public void testMethod() {
       Assertions.assertTrue(...);
    }
}
