Mocking queryForObject using Mockito

Question

Я использую Mockito для издевательства queryForObject, но я получаю NPE. Похоже, я настраиваю все необходимое.

long identity = getJdbcTemplate().queryForObject(getStatementConfiguration().getStatement(KeyConstants.CLIENT_USER_VENDOR_IDENTITY), Long.class); где я получаю NPE.

MUT

public IClientUserVendorDto insert(final IClientUserVendorDto dto) throws DaoException { 
try { 
    String sql1 = getStatementConfiguration().getStatement(KeyConstants.CLIENT_USER_VENDOR_RETRIEVE); 

    Object args[] = new Object[] { 
      dto.getClientUserId(), 
      dto.getVendor().getId(), 
      dto.getIdentifier(), 
      Boolean.TRUE, 
     dto.getCreatedBy(), 
     dto.getLastModifiedBy()}; 

    //insert 
    String sql = getStatementConfiguration().getStatement(KeyConstants.CLIENT_USER_VENDOR_INSERT); 
    getJdbcTemplate().update(sql, args); 

    //Retrieve 
    long identity = getJdbcTemplate().queryForObject(getStatementConfiguration().getStatement(KeyConstants.CLIENT_USER_VENDOR_IDENTITY), Long.class); 
    return (ClientUserVendorDto) getJdbcTemplate().queryForObject(sql1, new Object[] {identity}, new ClientUserVendorRowMapper()); 
} catch (Exception e) { 
    String message = "An exception occurred inserting a Client User Vendor."; 
    IExceptionHandlerResponse r = getExceptionHandler().handleData(e, DaoException.class, message); 
    if (r.isRethrow()) { 
     DaoException daoe = (DaoException) r.getThrowable(); 
     throw daoe; 
    } 
    throw (DaoException)r.getThrowable(); 
} finally { 
} 
} 

Junit

public void testInsert() throws Exception { 
    AppContext.setApplicationContext(applicationContext); 
    IVendorDto v = new VendorDto(); 

    IClientUserVendorDto userDto = new ClientUserVendorDto(); 
    userDto.setActive(true); 
    userDto.setClientUserId(new Long(1220)); 
    userDto.setIdentifier("JUnit-ID"); 
    userDto.setVendor(v); 
    v.setId(new Long(123)); 
    userDto.setCreatedBy("SYSTEM"); 
    userDto.setLastModifiedBy("Junit"); 

    ClientUserVendorDao dao = new ClientUserVendorDao(); 
    dao.setConfiguration(daoConfiguration); 
    dao.setJdbcTemplate(jdbcTemplate); 

    BaseJdbcDao baseDao = Mockito.mock(BaseJdbcDao.class); 
    BaseDao baseDao2 = Mockito.mock(BaseDao.class); 
    IStatementConfiguration stmtConfiguration = Mockito.mock(IStatementConfiguration.class); 

    Mockito.when(baseDao.getJdbcTemplate()).thenReturn(jdbcTemplate); 

    IDaoConfiguration configuration = new DaoConfiguration(); 
    configuration.setStatement(stmtConfiguration); 
    dao.setConfiguration(configuration); 

    Mockito.when(baseDao.getJdbcTemplate().queryForObject(Mockito.any(String.class), (RowMapper<Long>) Mockito.any(Object.class))).thenReturn(123L); 

    userDto = dao.insert(userDto); 

} 

Answer 1

Я узнал, что была проблема. queryForObject не возвращал длинное значение. Итак, вот исправление для него.

@Test 
public void testInsert() throws Exception { 
    IClientUserVendorDto iClientUserVendorDto = new ClientUserVendorDto(); 
    iClientUserVendorDto.setClientUserId(new Long(1007)); 

    IVendorDto iVendorDto = new VendorDto(); 
    iVendorDto.setId(new Long(1008)); 

    iClientUserVendorDto.setVendor(iVendorDto); 
    iClientUserVendorDto.setIdentifier("GW_SYS_USER"); 
    iClientUserVendorDto.setActive(true); 
    iClientUserVendorDto.setCreatedBy("SYSTEM"); 
    iClientUserVendorDto.setLastModifiedBy("SYSTEM"); 

    JdbcTemplate jdbcTemplate = Mockito.mock(JdbcTemplate.class); 
    ClientUserVendorDao clientUserVendroDao2 = Mockito.mock(ClientUserVendorDao.class); 
    IDaoConfiguration iDaoConfiguration = Mockito.mock(IDaoConfiguration.class); 
    IStatementConfiguration iStatementConfiguration = Mockito.mock(IStatementConfiguration.class); 

    Mockito.when(iDaoConfiguration.getStatement()).thenReturn(iStatementConfiguration); 
    Mockito.when(iStatementConfiguration.getStatement(Mockito.any(String.class))).thenReturn("JUnit"); 
    Mockito.when(clientUserVendroDao2.getJdbcTemplate()).thenReturn(jdbcTemplate); 
    Mockito.when(jdbcTemplate.queryForObject(Mockito.anyString(), Matchers.eq(Long.class))).thenReturn(1007L); 

    ClientUserVendorDao clientUserVendorDao = new ClientUserVendorDao(); 
    clientUserVendorDao.setConfiguration(iDaoConfiguration); 
    clientUserVendorDao.setJdbcTemplate(jdbcTemplate); 

    iClientUserVendorDto = clientUserVendorDao.insert(iClientUserVendorDto);
