Spring Boot #DataJpaTest stuck at HHH000400: Using dialect: org.hibernate.dialect.Oracle12cDialect - spring-boot

Question

I have a JUnit 5 test that isn't working, it gets stuck as shown below:
2020-04-03 16:53:23.207 INFO 2788 --- [ main] .i.p.d.r.CustomerReferenceRepositoryTest :

The test is annotated like this:
#DataJpaTest
#AutoConfigureTestDatabase(replace = Replace.NONE)
#ContextConfiguration(classes = TestDALConfig.class)
class CustomerReferenceRepositoryTest {
The test gets stuck and when I stop it manually I get this error messsage:
No tests found with test runner 'JUnit 5'
The test it self is very simple:
#Test
public void notNull() {
assertThat(customerReferenceRepository).isNotNull();
}
The complete unit test
package <removed>.payment.dal.repository;
import static org.assertj.core.api.Assertions.assertThat;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;

import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.test.context.ContextConfiguration;
import aero.sita.pts.ir.payment.config.TestDALConfig;
#DataJpaTest
#AutoConfigureTestDatabase(replace = Replace.NONE)
#ContextConfiguration(classes = TestDALConfig.class)
class CustomerReferenceRepositoryTest {
#Autowired
private CustomerReferenceRepository customerReferenceRepository;
public CustomerReferenceRepositoryTest() {
super();
}
#Test
public void notNull() {
assertThat(customerReferenceRepository).isNotNull();
}
}

CustomerReferenceRepository

#Transactional(propagation = Propagation.SUPPORTS, readOnly = true)
#Repository
public interface CustomerReferenceRepository extends PagingAndSortingRepository<CustomerReferenceDTO, Long> {
}
Can anyone shed some light on this?
Thanks

Answer 1

In your application yaml or properties file , try updating below !
spring.jpa.ddl-auto: none

Answer 2

Please verify the import in the entity class. For example for Date, the correct import is:
java.util.Date
Not:
java.sql.Date
