jUnit Unexpected method call DAO Easymock
提问by Mitja Rogl
I am newbie with mock testing. I want to test my DAO for users. Here is my code.
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);
}
When I run it I get this error:
当我运行它时，我收到此错误：

Your UserService#registrationmethod calls UserDAO#checkUsermethod, so you need to add it to expectation list. I don't know its parameters, so I am providing you only sample for addUser call below:
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，所以我只为您提供以下 addUser 调用的示例：
@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);
}
