Mockito NullPointerException DataSourceTransactionManager.getTransaction()

Question

Ich habe eine nullPointerException, wenn ich versuche, eine DataSourceTransactionManager mock, ich nur eine Methode ohne Zugriff auf die DB zu testen.

Vielleicht mache ich etwas falsch, aber ich weiß nicht was.

Testclass

@RunWith(MockitoJUnitRunner.class) 
public class VdpDirectshipDAOImplUT { 

    Logger logger = LoggerFactory.getLogger(getClass()); 

    @InjectMocks 
    private VdpDirectshipDAOImpl dao; 

    @Mock 
    private DataSourceTransactionManager oracleTxManager; 

    @Mock 
    TransactionStatus transactionStatus; 

    @Mock 
    TransactionDefinition transactionDefinition; 

    @Test 
    public void testSubmitDSOrder() { 
     // given 
     int result = -1; 
     VdpDirectShipSession vdpDirectShipSession = new VdpDirectShipSession(); 
     String vnetUserId = "10624802"; 

     // when 
     try { 
      result = dao.submitDSOrder(vdpDirectShipSession, vnetUserId); 
      logger.info("result: {}", result); 

     } catch (DirectShipDataAccessException e) { 
      fail(e.getMessage()); 
     } 

     // then 
     assertTrue("SKU invalid correction", result > 0); 
    } 

    @Before 
    public void setup() { 
     MockitoAnnotations.initMocks(this); 
     oracleTxManager = Mockito.mock(DataSourceTransactionManager.class); 
     Mockito.when(oracleTxManager.getTransaction(transactionDefinition)).thenReturn(Mockito.mock(TransactionStatus.class)); 
    } 

} 

DAO

public class VdpDirectshipDAOImpl extends SimpleJdbcDaoSupport implements 
     VdpDirectshipDAO { 

    /** 
    * transactionManager for Oracle Database 
    */ 
    private DataSourceTransactionManager oracleTxManager; 


    .... 

    @Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class) 
    public int submitDSOrder(final VdpDirectShipSession vdpDirectshipService, 
       final String vnetUserId) throws DirectShipDataAccessException { 

     ... 
      final TransactionDefinition def = new DefaultTransactionDefinition(); 
      final TransactionStatus status = oracleTxManager.getTransaction(def); 

     ... 
    } 
}

Ich benutze Java 5, Spring 2.0 und Junit 4.12 und ich kann ihre Versionen nicht aktualisieren.

Answer 1

Die richtige Implementierung für meine war die nächste.

@Spy 
private DataSourceTransactionManager oracleTxManager; 

... 

oracleTxManager.setDataSource(Mockito.mock(DataSource.class, Mockito.RETURNS_MOCKS));
