Spring #Transactional and rollback not working, spring integration tests - spring

Question

I'm doing an integration test in spring and in this example I testing a service layer.
I have a problem where during the addition test in the service, rollback not working, and always add an item to the base ,but not delete it.
I put annotation # Transactional and # TestPropertySource on test class,
also have application-test.properties and the test is successful but the rollback is not executed and a new item is always added to the test database.
My test class and test method for add address(last one):
#RunWith(SpringRunner.class)
#SpringBootTest(classes = TicketServiceApplication.class)
#Transactional
#TestPropertySource("classpath:application-test.properties")
public class AddressServiceIntegrationTest {
#Autowired
private AddressService addressService;
#Autowired
private AddressRepository addressRepository;
#Test
public void findAllSuccessTest(){
List<Address> result = addressService.finfAllAddress();
assertNotNull(result);
assertFalse(result.isEmpty());
assertEquals(2, result.size());
}
#Test
public void findOneAddressExistTest_thenReturnAddress(){
Long id = AddressConst.VALID_ID_ADDRESS;
Address a = addressService.findOneAddress(id);
assertEquals(id, a.getId());
}
#Test(expected = EntityNotFoundException.class)
public void findOneAddressNotExistTest_thenThrowException(){
Long id = AddressConst.NOT_VALID_ID_ADDRESS;
Address a = addressService.findOneAddress(id);
}
#Test
public void addAddressSuccessTest(){
int sizeBeforeAdd = addressRepository.findAll().size();
Address address = AddressConst.newAddressToAdd();
Address result = addressService.addAddress(address);
int sizeAfterAdd = addressRepository.findAll().size();
assertNotNull(result);
assertEquals(sizeBeforeAdd+1, sizeAfterAdd);
assertEquals(address.getCity(), result.getCity());
assertEquals(address.getState(), result.getState());
assertEquals(address.getNumber(), result.getNumber());
assertEquals(address.getLatitude(), result.getLatitude());
assertEquals(address.getLongitude(), result.getLongitude());
assertEquals(address.getStreet(), result.getStreet());
}
}
My application-test.properties :
spring.datasource.url= jdbc:mysql://localhost:3306/kts_test&useSSL=false&
useUnicode=true&characterEncoding=utf8
spring.datasource.username = root
spring.datasource.password = root
spring.jpa.show-sql = true
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
And when execute add address test, every time in my kts_test data base ( db used for testing) is added new item and not rollback.
This is a log from the console where you can see that the rollback was called but did not execute, because when I refresh the database after the test the new item was left, it was not deleted.
INFO 10216 --- [ main] o.s.t.c.transaction.TransactionContext : Rolled back transaction for test: [DefaultTestContext#3e58a80e testClass = AddressServiceIntegrationTest, testInstance = com.ftn.services.address.AddressServiceIntegrationTest#4678ec43, testMethod = addAddressSuccessTest#AddressServiceIntegrationTest, testException = [null],...
Lastly, to write that I tried #Transactional above methods, I also tried # Rollback above methods or # Rollback (true), tried changing application-test.properties and I no longer know what the error might be.
If anyone can help I would be grateful. Thank you.

Hibernate is by default creating tables with MyISAM storage engine - this engine does not support transactions. You need to have InnoDB tables:
Either manage your DB migrations manually with a tool like Flyway (imho preferred option so you can have a complete control) and turn off recreating database in tests.
Or set the correct engine in configuration:
spring.jpa.properties.hibernate.dialect.storage_engine=innodb
OR (deprecated)
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
