Question

只是想问一下，因为我被困在测试用例中并且因为＆＃34而出现错误;实际上，与这个模拟器没有交互＃34;

我创建了一个正在进行CRUD操作的Dao实现类。

public class EmployeeDaoImpl implements EmployeeDao {
       @Override
        public void saveEmployee(EmployeeDetails employee) {

            Session session = HibernateUtil.getSessionFactory().openSession();
            Transaction transaction = session.beginTransaction();
            session.save(employee); 
            transaction.commit();
            session.close();

        }
    }

对于上述课程，我正在使用Mockito构建测试。所以对于我上面的saveEmployee方法Session，TRansaction我把它作为Mock对象，现在我需要检查会话，保存方法和事务。

所以我在下面写了Mockito代码：

/ ** * * /

package sandeep.test;

import static org.junit.Assert.*;

import javax.transaction.HeuristicMixedException;
import javax.transaction.HeuristicRollbackException;
import javax.transaction.RollbackException;
import javax.transaction.SystemException;
import javax.transaction.Transaction;

import junit.framework.Assert;

import org.hibernate.Session;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.runners.MockitoJUnitRunner;

import sandeep.DAO.EmployeeDao;
import sandeep.DAOImpl.EmployeeDaoImpl;
import sandeep.DAOImpl.HibernateUtil;
import sandeep.pojo.EmployeeDetails;
import static org.mockito.Mockito.*;


/**
 * @author sandeep
 *
 */
@RunWith(MockitoJUnitRunner.class)
public class EmployeeDaoImplTest {

    @Mock
    EmployeeDetails edt;
    @Mock
    Session session ;
    @Mock
    Transaction transaction;

    @InjectMocks
    EmployeeDaoImpl edi = new EmployeeDaoImpl();

    @Before
    public void setUp() throws Exception {
        //eimpl = new EmployeeDaoImpl();
        //emp= mock(EmployeeDao.class);
    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testSaveEmployee(){
        edi.saveEmployee(getEmployeeDetails());
        // But here i am getting the error as zero interactions
        verify(session, times(1)).save(EmployeeDetails.class);  
    }

    public EmployeeDetails getEmployeeDetails(){

        edt = new EmployeeDetails();
        edt.setEname("sandeep");
        edt.setId(2);
        edt.setEnumber("hoi");
        return edt;

    }   
}

我调试了代码，代码传递到我IDE中的所有断点，当我执行这3个值时，它将被添加到数据库中，但我的测试用例将因为没有交互而失败。

您的测试中的Session模拟与EmployeeDaoImpl中使用的对象不同#saveEmployee

使用Session参数为EmployeeDaoImpl实现构造函数，并在saveEmployee（）方法中使用该参数。这允许您的@InjectMocks按预期工作。

@RunWith(MockitoJUnitRunner.class)
public class MockitoTest {

    @Mock
    Session session;

    @InjectMocks
    EmployeeDaoImpl edi;

    @Test
    public void testSaveEmployee(){
        edi.saveEmployee();

        verify(session, times(1)).save();
    }
}

class Session {
    void save() {
        System.out.println("saving");
    }
}

interface EmployeeDao {
    void saveEmployee();
}

class EmployeeDaoImpl implements EmployeeDao {
    private Session session;

    public EmployeeDaoImpl(Session session) {
        this.session = session;
    }

    @Override
    public void saveEmployee() {
        session.save();
    }
}

Mockito测试失败：实际上，与此模拟
