Unit tests with Powermockrunner showing errors

Question

I have two classes of tests that are run with PowerMockRunner and extending the class JdbcTest.

Below follows their source code:

Test class ScimImportUsersBusinessTest

@RunWith(PowerMockRunner.class)
@PrepareForTest({DaoFactory.class})
public class ScimImportUsersBusinessTest extends JdbcTest { 
    
    @Mock
    private IdGeneratorSequenceDao idGeneratorSequenceDao;      
    
    
    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this); 
        PowerMockito.mockStatic(DaoFactory.class);
        PowerMockito.when(DaoFactory.getDao(IdGeneratorSequenceDao.class)).thenReturn(idGeneratorSequenceDao);
        
    }   
    
    @Test
    public void importUsersScimEmptyListTest() throws ScimImportUserException {
        (...)
    }
    
    @Test
    public void importUsersScimWithManagerTest() throws ScimImportUserException, SQLException {
        (...)   
    }
    
    @Test
    public void importUsersScimNewDepartmentAndPositionTest() throws ScimImportUserException, SQLException {
        (...)       
    }
}

Test class ScimImportUserDaoDefaultTest

@RunWith(PowerMockRunner.class)
@PrepareForTest({ DaoFactory.class })
public class ScimImportUserDaoDefaultTest extends JdbcTest {
    
    @Mock
    private IdGeneratorSequenceDao idGeneratorSequenceDao;  

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        PowerMockito.mockStatic(DaoFactory.class);
        PowerMockito.when(DaoFactory.getDao(IdGeneratorSequenceDao.class)).thenReturn(idGeneratorSequenceDao);
    }   

        
    @Test
    public void importUserAdinterfaceValidadeCountRecords() throws ScimImportUserException, SQLException {
        (...)
    }

    @Test
    public void importUserAdinterfaceValidadeFields() throws ScimImportUserException, SQLException {
        (...)
    }
        
    //outros testes
    (...)   

}

If I squeegee separately each of the above classes with the Junit, the tests are run without errors.

Now, when run the two test classes with Junit together (for example, running all test classes of the project in which they are present), the test class ScimImportUserDaoDefaultTest wheel without errors and the test class ScimImportUsersBusinessTest glitch.

Follows below the stack trace error that occurs in the attempt to run the class ScimImportUsersBusinessTest (by running all project tests) :

1. Why does this occur error when I run both test classes together?

2. How to correct this error?
