I am facing issue when trying to Run Junit Test class for my service class using Mockito.The JPA query is not getting executed. My DAO and service classes work fine when i run my spring classes , i am facing issue only when running Mockito Junit class.Below is the code.
MY service class
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
@Service
public class DataBatchProcessorSvc {
@Autowired
DatasBatcProcessorDao dao;
@Autowired
DataAuditDaoImpl auditDao;
@Transactional
public Map> fetchBatchData() {
return dao.fetchBatchData();
}
@Transactional(propagation=Propagation.REQUIRED)
public void saveBatchData(List DataList) {
dao.saveBatchData(DataList);
auditDao.saveAuditData(DataList);
}
@Transactional
public void processBatch(List DataList){
this.saveBatchData(DataList);
auditDao.saveAuditData(DataList);
}
}
My Dao class
import java.util.ArrayList;
import java.util.Collection;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
@Repository
public class DatasBatcProcessorDao {
@PersistenceContext(unitName = "PersistenceUnitA")
EntityManager entityManager;
public Map> fetchBatchData() {
Query query = entityManager.createQuery("SELECT e FROM Data e");
Collection resultList = query.getResultList();
Map> DataDetails = new HashMap>();
Iterator itr = resultList.iterator();
while (itr.hasNext()) {
Data Data = itr.next();
String organizationKey = Data.getOrganizationId();
if (DataDetails.containsKey(organizationKey)) {
List DatasList = DataDetails.remove(organizationKey);
DatasList.add(Data);
DataDetails.put(organizationKey, DatasList);
} else {
List DatasList = new ArrayList();
DatasList.add(Data);
DataDetails.put(organizationKey, DatasList);
}
}
return DataDetails;
}
}
My Mockit Test class
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 {
@Autowired
@InjectMocks
DatasBatcProcessorDao processtDao;
@Autowired
@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"));
}
}
MY JPA Class
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name = "Data_details")
public class Data {
@Id
@Column(name = "ID", nullable = false)
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
@Column(name = "Dataaint_name", nullable = true)
private String DataantName;
@Column(name="organization_name",nullable=true)
private String organizationId;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getDataantName() {
return DataantName;
}
public void setDataantName(String DataantName) {
this.DataantName = DataantName;
}
public String getOrganizationId() {
return organizationId;
}
public void setOrganizationId(String organizationId) {
this.organizationId = organizationId;
}
}
When i am trying to this code . I get that Below exception
org.hibernate.hql.internal.ast.QuerySyntaxException: Data is not mapped [SELECT e FROM Data e]
when executing
Mockito.when(processtDao.fetchBatchData()).thenReturn(organizationDatas);
and i also assume that Mockito create mock object , since i am mocking my DAO class the call to my dao should not actual hit DB, please let me know if I am wrong .
Stack Trace:
java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: Data is not mapped [SELECT e FROM Data e]
