Do you clean up after you're done?

Hello,
I think we're all used to using @Transactional inside our JUnit tests, so the database can remain in a clean state.

This article takes a different position, saying that each test should use some unique data, and therefore you don't need to rollback after a test: https://arialdomartini.github.io/when-im-done-i-dont-clean-up

Wondering if anybody follows those practices?

Why do we need to use @Autowired inside Spring Boot Tests?

Starting from Spring 5, we don't need to specify @Autowired inside a Spring bean.

For instance I can do this and it works just fine:

@Service
public class OwnerService {
    private final OwnerRepository ownerRepository;

    public OwnerService(OwnerRepository ownerRepository) {
        this.ownerRepository = ownerRepository;
    }
}

However, in a Spring Boot test, @Autowired still has to be explicit.

@SpringBootTest
public class VisitServiceTest {
    private final VisitService visitService;

    @Autowired
    public VisitServiceTest(VisitService visitService) {
        this.visitService = visitService;
    }
}

Anybody understands why Spring Boot Tests are different?
