当我尝试使用JPA查询为我的服务类运行Junit测试类时,我遇到了问题Mockito.TheJPA查询没有被执行。当我运行我的Spring类时,我的DAO和服务类工作正常,我只在运行Mockito Junit时遇到了问题class.Below是代码。

public class DataBatchProcessorSvc {
@Autowired
DatasBatcProcessorDao dao;
@Autowired
DataAuditDaoImpl auditDao;
@Transactional
public Map<String, List<Data>> fetchBatchData() {
return dao.fetchBatchData();
}
@Transactional(propagation=Propagation.REQUIRED)
public <T> void saveBatchData(List<T> DataList) {
dao.saveBatchData(DataList);
auditDao.saveAuditData(DataList);
}
@Transactional
public <T> void processBatch(List<T> DataList){
this.saveBatchData(DataList);
auditDao.saveAuditData(DataList);
}
}

当我尝试此代码.我得到下面的例外
org.hibernate.hql.internal.ast网站。QuerySyntaxException:数据未映射[SELECT e FROM Data e]
执行时
Mockito.when(processtDao.fetchBatchData()).thenReturn(organizationDatas);
我还假设Mockito创建了模拟对象,因为我正在模拟我的DAO类,对我的DAO的调用实际上不应该命中DB,如果我错了,请告诉我。

我终于解决了这个问题。
我的代码有两个问题
1) 使用@autwired:这将注入实际对象,而不是模拟对象2)何时使用@InjectMock和@Mock,这里有漂亮的描述
我的Dao是应该被模仿的对象,而我的服务类是这些模仿必须被注入的地方,因此我用@Mock标记了我的Dao,用@InjectMock标记了服务类
下面是修改后的代码

Data.setOrganizationId("Mindtree");
Data Data2 = new Data();
Data2.setDataantName("Vinay");
Data2.setOrganizationId("Mindtree");
dataList.add(Data);
dataList.add(Data2);
organizationDatas.put("Mindtree", dataList);
Mockito.when(processtDao.fetchBatchData()).thenReturn(organizationDatas);
}
@After

}
@Test
public void saveAllAudit() {
Map<String, List<Data>> batchData = processSvc.fetchBatchData();
assertEquals(2, batchData.get("Mindtree").size());
}
}
如果我理解正确,DataBatcProcessorDao
的实例应该是一个Mock对象。然而,您的实现创建了一个真实的对象。尝试更改此代码
@Autowired // Autowired to get mockito to inject into the spring-handled dao
@InjectMocks
DatasBatcProcessorDao processtDao;
到此代码:
@Mock
DatasBatcProcessorDao processtDao;
processtDao将成为模拟对象
问题内容: 我对Java单元测试非常陌生,听说Mockito框架对于测试非常有用。 我已经开发了一个REST Server(CRUD方法),现在我想对其进行测试,但是我不知道如何? 我什至不知道该测试程序应该如何开始。我的服务器应该在本地主机上运行,然后在该URL上进行调用(例如,本地主机:8888)? 这是我到目前为止尝试过的方法,但是我很确定这不是正确的方法。 这是方法的代码。 在此测试用

像组件一样,服务通常需要依赖,Angular通过服务类的构造函数注入。由于我们在Angular的引导过程之外初始化这些类,我们必须自己显式注入这些依赖。这是通过使用TestBed配置测试模块传回所需的依赖项(如HTTP模块)来实现的。
