Question

我是模拟测试的新手。我想为用户测试我的DAO。这是我的代码。

private UserService service;
private UserDAO mockDAO;

@Before
public void setUp(){
    service=new UserService();
    mockDAO=createMock(UserDAO.class);
    service.setUserDao(mockDAO);
}

@Test
public void testAddUser(){

    mockDAO.addUser( (User) EasyMock.anyObject());
    EasyMock.replay(mockDAO);
    User u=new User();
    u.setUserName("x");
    u.setPass("y");
    service.registration(u);
    EasyMock.verify(mockDAO);

}

当我运行它时，我收到此错误：

更新了stacktrace：

  java.lang.AssertionError: 
  Unexpected method call  UserDAO.checkUser(si.soa.rentacar.model.User@3655dba1):

您的UserService#registration方法调用UserDAO#checkUser方法，因此您需要将其添加到期望列表中。我不知道它的参数，所以我只为你提供下面的addUser调用示例：

@Test
public void testAddUser(){

    // prepare data
    User u = new User();
    u.setUserName("x");
    u.setPass("y");

    // expectation section
    mockDAO.addUser(u);
    EasyMock.expectLastCall();
    EasyMock.expect(mockDAO.checkUser(u)).andReturn(true);

    EasyMock.replay(mockDAO);

    // scenario
    service.registration(u);

    // verification
    EasyMock.verify(mockDAO);

}

jUnit意外的方法调用DAO Easymock
