Testing Spring HIbernate JPA service layer with Mockito issue

manpreet Best Answer 2 years ago

_x000D_ Finally I was able to resolve the issue . There were two problems with my code 1) Using @autwired : This will inject actual object and not Mock Object 2) When to use @InjectMock and @Mock you get beautiful description here My Dao was the object that should be mocked and my service class is the place were these mocks have to be injected hence i made changes Marked myDao with @Mock and service class with @InjectMock Below is the modified code import static junit.framework.Assert.assertEquals; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.mockito.InjectMocks; import org.mockito.MockitoAnnotations; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class TestDataBatchProcessSvc { @Mock DatasBatcProcessorDao processtDao; @InjectMocks DataBatchProcessorSvc processSvc; @Before public void setUp() { MockitoAnnotations.initMocks(this); Map> organizationDatas = new HashMap>(); List dataList = new ArrayList(); Data Data = new Data(); Data.setDataantName("Vinay"); 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 public void tearDown() { } @Test public void saveAllAudit() { Map> batchData = processSvc.fetchBatchData(); assertEquals(2, batchData.get("Mindtree").size()); } }
