Question

我正在为我的项目的DAO类编写测试。但是，当我使用Mockito的verify()方法时，它会抛出NullPointerException，因为createQuery()方法会返回null。我该如何解决？

@Mock(answer = Answers.RETURNS_DEEP_STUBS)
private EntityManager entityManagerMock;

@InjectMocks
private TaksitPlanSatiriDao taksitPlanSatiriDao = new TaksitPlanSatiriDaoJpa();

@Before
public void setUp() {
    taksitPlanSatiriEntity = new TaksitPlanSatiriEntity();
}
@Test
public void shouldUpdateWhenGuncelleCalledWithTaksitPlanSatiriEntity() {
    taksitPlanSatiriDao.guncelle(taksitPlanSatiriEntity);
    Mockito.verify(entityManagerMock).createQuery(ArgumentMatchers.anyString()).executeUpdate();
}

尝试：

    ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
    WITH SERDEPROPERTIES (
      'field.delim'=',',
      'line.delim'='\n',
      'serialization.format'=',',
      'serialization.encoding'='UTF-8')
    STORED AS INPUTFORMAT
      'org.apache.hadoop.mapred.TextInputFormat'
    OUTPUTFORMAT
      'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
    TBLPROPERTIES("skip.header.line.count"="1")

这是基于“深层存根”文档的：
