Question

在DAO中为getSession方法编写测试类时遇到了一些麻烦代码

Test class

import org.hibernate.SessionFactory;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import static org.mockito.Mockito.when;


public class SessionDaoImplTest {

private SessionDaoImpl sessionDao;

@Mock
private SessionFactory session;

@Before
public void setUp() {
    MockitoAnnotations.initMocks(this);
    sessionDao = new SessionDaoImpl(session);
}

@Test
public void testGetCurrentSession() throws Exception {
     when(sessionDao.getCurrentSession()).
thenReturn(session.getCurrentSession());
}
}

在测试类

下

import com.oleg.project.dao.Session.SessionDao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

public class SessionDaoImpl implements SessionDao {

@Autowired
private SessionFactory sessionFactory;

SessionDaoImpl(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

public Session getCurrentSession() {
    Session session = sessionFactory.getCurrentSession();
    return session;
}
}

栈跟踪 org.mockito.exceptions.misusing.UnfinishedStubbingException：这里检测到未完成的存根： - ＆GT;在com.oleg.project.dao.Session.impl。 SessionDaoImplTest.testGetCurrentSession（SessionDaoImplTest.java:28）

E.g. thenReturn() may be missing.
Examples of correct stubbing:
when(mock.isOk()).thenReturn(true);
when(mock.isOk()).thenThrow(exception);
doThrow(exception).when(mock).someVoidMethod();
Hints:
1. missing thenReturn()
2. you are trying to stub a final method, you naughty developer!
3: you are stubbing the behaviour of another mock inside before     
'thenReturn' instruction if completed

Answer 1

变量sessionDao不是模拟。

我认为你的意思是sessionDao = spy(new SessionDaoImpl(session));

修改您还必须将session.getCurrentSession()提取到局部变量中：

Session currentSession = session.getCurrentSession(); when(sessionDao.getCurrentSession()).thenReturn(currentSession);
