Hi
I am new to Mockito and trying to write a test for my demo project. I have a project, using Spring 5 and Hibernate. I have a DAO class which use Hibernate session and query.

@Repository
@Transactional
public class CustomerDaoImpl implements CustomerDao {

@Autowired
   private SessionFactory sessionFactory;

@Override
public Customer getCustomerById(int id) {
Session session = null;
Customer customer = null;

try{
session = sessionFactory.openSession();
customer = session.find(Customer.class, id);
}catch(Exception e) {
throw (e);
}finally {
session.close();
}
return customer;
}
}

// Test Class
@ExtendWith(SpringExtension.class)
@ExtendWith(MockitoExtension.class)
@ContextConfiguration(locations = "classpath:spring-hibernate-config-test.xml")
public class CustomerDaoTest {

@InjectMocks
private CustomerDaoImpl customerDao;

@Mock
SessionFactory sessionFactory;

Customer customer;

@Before
public void setupMock(){
    MockitoAnnotations.initMocks(this);
    sessionFactory = mock(SessionFactory.class);
    customerDao.setSessionFactory(sessionFactory);
}

@Test
@Transactional
@Rollback(true)
@DisplayName("DAO: Find customer by given id")
public void testGetCustomerById() {
int customerId = 14;
Customer customer = new Customer(14, "Mike");
when(sessionFactory.openSession().find(Customer.class, customerId)).thenReturn(customer);

assertNotNull(customer);
    assertEquals(customerId, customer.getIfCustomerId());
}
}

Error:
java.lang.NullPointerException
at com.primis.dao.CustomerDaoTest.testGetCustomerById(CustomerDaoTest.java:61)

For some reason my session is null. Please can someone advice where I am going wrong.

Thank you

Hi

I am new Spring boots, JUnit 5 and Mockito.
I am trying to learn this technolgy.
I have simple RestController with one method createUser.
When I test this controller method through Postman, it work fine.
But when run unit test (Shown below), I am getting NullPointerException (marked inside method).
It is not creating userResponse. Here is the code;

Please can someone advice me where I am going wrong.

@RestController
@RequestMapping("/user")
public class UserRestController {

@Autowired
UserService userService;

@PostMapping(path="save", consumes= {MediaType.APPLICATION_JSON_VALUE}, produces= {MediaType.APPLICATION_JSON_VALUE})
public String createUser(@RequestBody User user) {
User userResponse = userService.createUser(user);
System.out.println("userResponse ..: " + userResponse );  // These is null when Test run

return String.valueOf(userResponse.getId());
}
} //  end UserController


@Service
public class UserServiceImpl implements UserService {

@Autowired
private UserRepository userRepository;

@Override
public User createUser(User user) {
User userResponse = userRepository.save(user);
return userResponse;
}
}

@WebMvcTest(UserRestController.class)
public class UserRestControllerTest {

@Autowired
private MockMvc mockMvc;

@Autowired
private ObjectMapper objectMapper;

@MockBean
UserService userService;

@Test    
@DisplayName("UserRestController createUser Test")
public void createUserTest() throws JsonProcessingException, Exception {

User newUser = new User("Mr", "Dabby", "Wall", 27);
User savedUser = new User(1, "Mr", "Dabby", "Wall", 27);

when(userService.createUser(newUser)).thenReturn(savedUser);

String url = "/user/save";
this.mockMvc.perform(post(url)
.contentType(MediaType.APPLICATION_JSON)
.content(objectMapper.writeValueAsString(newUser)))
.andExpect(status().isOk())
.andExpect(content().string("1")
);
}
}


Here is error I am getting;

Hi

I am new to spring environment. I have created small test spring project through STS.
Project name: SPTest
base package name: uk.co.ifTest

When I run and open this project browser through Eclipse. It work fine, but url, it put in the browser is http://localhost:8080/ifTest/, instead of http://localhost:8080/SPTest/.
I guess, it is adding base package name.

Is there any way I can open project with http://localhost:8080/SPTest/.

Thanks

Hi

I am using MYSQL Database with Eclipse helios.
I am having problem adding object to POJO (Class created by Hibernate reverse engineering).
I have two tables customer and stitle. I have created One-to-Many relationship in MYSQL between this two tables.
titleId is foreign key in customer table. so one to many relation exist.

customer

customerId as int(11) primary Key
titleId as Int(11) foreignKey FK_CTitleId (which is match to titleId in stitle table)
firstname as string(45)

stable

titleId as int(11) primary Key
title as string(45)

When I run reverse engineering, I get two object STitle.java and Customer.java.
Also get two Customer.hbm.xml and Stitle.hbm.xml.
But I am getting titleId in Customer object as an Integer and not as STitle object.

Here is my hibernate-reverse-engineering file.


JAVA object it created



I don't understand why it is creating titleId as integer. It suppose to be object for table sTitle.

Please can someone help me.

Many thanks
