JUnit 5 Eclipse Java Testing

I am doing JUnit5 testing using Mockito and here is the full code please have a look and let me know how to fix this :
package hotel.entities;
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.junit.jupiter.api.function.Executable;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Spy;
import org.mockito.junit.jupiter.MockitoExtension;
import hotel.credit.CreditCard;
import static org.mockito.Mockito.*;
import static org.mockito.ArgumentMatchers.any;
import static org.mockito.ArgumentMatchers.anyInt;
import java.util.ArrayList;
import java.util.Date;
class RoomTest {
#Mock Booking booking;
#Spy ArrayList <Booking> bookings;
int roomID = 1;
int stayLength = 1;
RoomType roomtype = RoomType.SINGLE;
#InjectMocks Room room = new Room(roomID, roomtype);
#BeforeEach
void setUp() throws Exception {
room = new Room(roomID,roomtype);
//booking = new Booking(guest, room,bookedArrival,stayLength,numberOfOccupants,creditCard);
//booking = new checkout(booking);
}
#AfterEach
void tearDown() throws Exception {
}
#Test
void roomCheckin() {
room.checkin();
assertTrue(room.isAvailable(null, stayLength));
Executable e = () -> room.checkin();
Throwable t = assertThrows(RuntimeException.class, e);
}
#Test
void roomCheckout() {
bookings.add(booking);
room.checkin();
assertEquals(roomID , bookings.size());
assertTrue(room.isAvailable(null, stayLength));
room.checkout(booking);
verify(bookings).remove(booking);
assertTrue(room.isReady());
assertEquals(0,bookings.size());
}
}
I am getting error on this line while I am doing testing:
bookings.add(booking);
please tell me how can I fix this null pointer exception from the code so that it runs properly and my tests get successful.
Here is the complete error trace please guide me how to fix this issue:

Based on your code snippet, it looks like you have two methods i.e. book the hotel and check-out the same.
The general concept of unit test to test the code written in that particular class. So, your end goal will be to test book and checkout method in the different test case.
You are getting java.lang.NullPointerException because your bookings attribute is null due to wrong use of #Spy annotation.
#Spy
List <Booking> bookings = new ArrayList<>();
You should use #Spy as shown above and it will solve your null pointer exception:
You can refer below link to read how to use #Spy # https://www.baeldung.com/mockito-spy

NonUniqueObjectException - a different object with the same identifier value was already associated with the session

Trying to remove an Address object from the session I get this exception org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session.
The following is the calling source code :
//The relation between a User and an Address is Ont-To-One with no cascade at any of the joining columns (Address#user and User#address)
Address address = user.getAddress();
if(address!=null){
usr.setAddress(null);
//I have tried to merge before/after unbinding the object from the session, neither of both worked
//addressDao.merge(addressByAddress);
addressDao.unbindObjectFromSession(addressByAddress);
addressDao.remove(addressByAddress);
}
AddressDaoImpl.java
public class AddressDaoImpl extends GenericDaoImpl<Address> implements AddressDao {
private static org.apache.log4j.Logger log = Logger.getLogger(AddressDaoImpl.class);
public AddressDaoImpl() {
super(Address.class);
}
//omitted source code
}
GenericDaoImpl.java
public class GenericDaoImpl<T extends IdInterface> extends HibernateDaoSupport implements GenericDao<T> {
private static final Logger LOG = LoggerFactory.getLogger(GenericDaoImpl.class);

this.type = type;
}
#Override
public boolean remove(final T removeObject) {
getHibernateTemplate().delete(removeObject);
LOG.trace("An entity of type \"{}\" has been deleted from db. ID: {}", type.getSimpleName(), removeObject.getId());
return true;
}
#Override

What you're trying to accomplish should work just like this:
// Start a spring transaction that wraps the operation
#Transactional
public void removeAddressById(Long addressId) {
// I'm just locating the address from the database based on some provided id.
final Address address = addressDao.findById( addressId );
// break the association between the associated User and Address.
address.getUser().setAddress( null );
address.setUser( null );
// Update the user and remove the address
// If address owns the one-to-one association, then the merge is unnecessary
getHibernateTemplate().merge( user );
getHibernateTemplate().delete( address );
}
Since you are trying to delete/remove an entity, the object will be evicted from the persistence context by the persistence provider automatically.

InvalidDataAccessResourceUsage Exception in spring application test

Here is my model:-
DAO:-
public class User implements Serializable {
private int id;
private String name;
private String userIdentifier;
private String accountNumber;
private String baseURL;
private String proxy;
private int timeout;
private String configuration;
private boolean active;
// getters and setters for above variables
}
I am creating user in the test method and I have mandatory fields for the creation. Still I don't know why it is throwing error when I execute the test.
Test method:-
#RunWith(SpringRunner.class)
#SpringApplicationConfiguration(classes = TestApplication.class)
#WebAppConfiguration
public class UserRepositoryTest extends AbstractTransactionalJUnit4SpringContextTests {

How to solve this error ? Kindly help.

I solved this issue by changing the ddl-auto value from createordrop to create-drop in application.yml. It was my mistake. Thanks all for your time and suggestions.
ddl-auto property values are none, validate, update, create, create-drop. Refer here

NullPointerException because of the same hibernate constructor

I am using hibernate 4.2.0. I am having the following class:
#Entity
public class TestData {
#Id
#GeneratedValue
private Long id;
private String customerNr;
private String FirstName;
private String LastName;
/**
*
*/
public TestData() {
super();
}
/**
* #param customerNr
*/
public TestData(String customerNr) {
super();
this.customerNr = customerNr;
}
/**
* #param id
* #param customerNr
* #param firstName
* #param lastName
*/
public TestData(Long id, String customerNr, String firstName,
String lastName) {
super();
this.id = id;
this.customerNr = customerNr;
FirstName = firstName;
LastName = lastName;
}
//getter and setter etc.
}
To get all customerNr I am using the following query:
#Transactional
#SuppressWarnings("all")
public List<TestData> getCustomerNrFilter(String customerNr) {
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<TestData> criteria = cb.createQuery(TestData.class);
//which table we want to fetch
final Root root = criteria.from(TestData.class);
//create statement
criteria.select(cb.construct(TestData.class, root.get("customerNr"))).distinct(true);
// Pass the criteria list to the where method of criteria query
criteria.where(cb.and((Predicate[]) criteriaList.toArray(new Predicate[0])));
// Order by clause
criteria.orderBy(cb.asc(root.get("customerNr")));
return em.createQuery(criteria).getResultList();
}
public List createWhereCritera(String customerNr, CriteriaBuilder cb,
final Root root) {
// This list will contain all Predicates (where clauses)
List criteriaList = new ArrayList();
// CustomerNr: where condition: TestData.CustomerNr like '%'
Predicate predicateFirstName = cb.like(cb.upper(root.get("customerNr")),customerNr);
criteriaList.add(predicateFirstName);
return criteriaList;
}
As I see the customerNr uses this constructor to get my data:
/**
* #param customerNr
*/
public TestData(String customerNr) {
super();
this.customerNr = customerNr;
}
However, using the same query for `firstName`:
#Transactional
#SuppressWarnings("all")
public List<TestData> getCustomerNrFilter(String firstName) {
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<TestData> criteria = cb.createQuery(TestData.class);
//which table we want to fetch
final Root root = criteria.from(TestData.class);
//create statement
criteria.select(cb.construct(TestData.class, root.get("firstName"))).distinct(true);
// Pass the criteria list to the where method of criteria query
criteria.where(cb.and((Predicate[]) criteriaList.toArray(new Predicate[0])));
// Order by clause
criteria.orderBy(cb.asc(root.get("firstName")));
return em.createQuery(criteria).getResultList();
}
public List createWhereCritera(String firstName, CriteriaBuilder cb,
final Root root) {
// This list will contain all Predicates (where clauses)
List criteriaList = new ArrayList();
// firstName: where condition: TestData.firstName like '%'
Predicate predicateFirstName = cb.like(cb.upper(root.get("firstName")),firstName);
criteriaList.add(predicateFirstName);
return criteriaList;
}
However, firstName also tries to use the customerNr constructor to get my data:
/**
* #param customerNr
*/
public TestData(String customerNr) {
super();
this.customerNr = customerNr;
}
Right now, giving the data back gives me a Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException, because only the customerNr is queried and not the firstName.
I cannot really create two constructors of the same type, because then I would have a duplicated method. Furthermore, leaving the constructor out gives me the exception no appropriate constructor
Any recommendations what I should do?
UPDATE 1
Commenting all constructors out gives me:
Unable to locate appropriate constructor on class [com.Application.domain.TestData] [select distinct new com.Application.domain.TestData(generatedAlias0.customerNr) from com.Application.domain.TestData as generatedAlias0 where ( upper(generatedAlias0.customerNr) like :param0 ) and ( upper(generatedAlias0.firstName) like :param1 ) ...
I appreciate your replies!

UPDATE 3
Changing my method gives me the following exception:
#Transactional
#SuppressWarnings("all")

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<TestData> criteria = cb.createQuery(TestData.class);

//create statement
criteria.select(root.get("firstName")).distinct(true);
// Pass the criteria list to the where method of criteria query
criteria.where(cb.and((Predicate[]) criteriaList.toArray(new Predicate[0])));
// Order by clause
criteria.orderBy(cb.asc(root.get("firstName")));
List<String> resultList = em.createQuery(criteria).getResultList(); // EXCPETION: Type mismatch: cannot convert from List<TestData> to List<String>
return resultList;
}
public List createWhereCritera(String firstName, CriteriaBuilder cb,
final Root root) {
// This list will contain all Predicates (where clauses)
List criteriaList = new ArrayList();
// firstName: where condition: TestData.firstName like '%'
Predicate predicateFirstName = cb.like(cb.upper(root.get("firstName")),firstName);
criteriaList.add(predicateFirstName);
return criteriaList;
