UPD for Spring 2.x versions.

Spring 2.x supports new feature a SpringExtension for Junit 5 Jupiter, where all you have to do is:

1. Declare your test class with @ExtendWith(SpringExtension.class)

2. Inject your @BeforeAll (replacement for @BeforeClass in JUnit 5) with the bean

For example:

@ExtendWith(SpringExtension.class)
...
public void ITest {

    @BeforeAll
    public static void init(@Autowired EntityRepository dao) {
        dao.save(initialEntity);
    }

}

Assuming you correctly configured JUnit 5 Jupiter with Spring 2.x
