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.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

This is the code i have written below in junit. However it shows me a null pointer exception for the webdriver.
i have also printed "driver". it prints "drivernull"
*package demo;
import static org.junit.jupiter.api.Assertions.*;
import java.util.concurrent .TimeUnit;
import org.junit.Before;
import org.junit.jupiter.api.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
class Demo1 {
public WebDriver driver;
String url="www.google.com";
#Before
public void before() {
System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
driver = new ChromeDriver();
driver.get(url);
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
}
#Test
public void test() throws Exception {
System.out.println("driver"+driver);
Thread.sleep(2000);
driver.findElement(By.xpath("//*[#id=\'prm\']/div/a")).click();
}
}*
This is the failure trace

Please check chromedriver.exe path. It should be in D: drive.
I am not seeing anything incorrect in your code.
It seems that something in your before() throws an exception because driver is null. So get(url) or manage().
Most likely it is get(url) (you can see that precisely in your stack trace)
So new ChromeDriver() probably fails, check your installation.
Hence, when test is called, driver member variable is still null, so the display is "null".
the get started example explicits the protocol in the path. This is most likely unrelated but you should change
String url="www.google.com";
to
String url="http://www.google.com";
Please change
String url="www.google.com";
to
String url="http://www.google.com";
Why do we need to do because driver.get method is not adding protocol like "http" or "https" before your url
I have tried to run this code but it won't run... It just shows an error INFO: Detected dialect: W3C [Utils] [ERROR] [Error] java.lang.NullPointerException

java.lang.NullPointerException is usually caused when you try to use a reference that points to no location in memory (null) as though it were referencing an object. Calling a method on a null reference or trying to access a field of a null reference will trigger a NullPointerException.(https://stackoverflow.com/questions/218384/what-is-a-nullpointerexception-and-how-do-i-fix-it)

Any solution?
One of the instance fields in your controller is lacking an #FXML annotation. Since the field is private, the FXML loader is unable to inject the control reference into the field during loading. Here are your instance field declarations:
#FXML
private TextField txtCampo,txtCampo2;
#FXML
private Button btAdicionar,btConsultar;
#FXML
private TableView<Pessoa> tabValues;
#FXML
private TableColumn<Pessoa, Integer> tbcCod;
private TableColumn<Pessoa, String>tbcNome;
Notice that the last field, tbcNome, is not annotated. As a result, when your initialize method is called, the tbcNome field contains a null reference, resulting in the exception.
To fix your problem, all you may need to do is add the #FXML annotation to the instance field declaration for tbcNome.
You may have encouraged this error by adopting the habit of listing more than one variable in your type declarations, eg. private Button btAdicionar, btConsultar;. In my opinion, this is a bad habit that can encourage errors like this to happen. I would suggest that you try to adopt the coding style in which each instance field has its own type declaration statement.

As it says in the exception the zaneacademy_jms_tutorial_01 is not defined.
You need to configure it and assigne it to the topic/zaneacademy_jms_tutorial_01.
I would say, that the problem is your getInitialContext() which you configure mannaully, instead of returing the probably already configured context by new InitialContext();
My DAO layer code is as follows:
package com.app.dao;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.stereotype.Repository;
import com.app.pojo.InterviewerPojo;
#Repository("interviewer_details_dao")
public class InterviewerDetailsDaoImpl implements InterviewerDetailsDao {
#Resource(name="sessionFactory")
private SessionFactory factory;
/*private HibernateTemplate template;
public void setSessionFactory(){
template = new HibernateTemplate(factory);
}*/
/*private HibernateTemplate template = new HibernateTemplate(sessionFactory);*/
#Override
public void saveInterviewDetails(InterviewerPojo interviewerPojo) {
/* Session sess = factory.getCurrentSession();
try{
sess.getTransaction().wasCommitted();
Transaction trans = sess.beginTransaction();
System.out.println("a");
sess.saveOrUpdate(interviewerPojo);
sess.getTransaction().commit();}
catch(Exception e){
throw e;
}*/
System.out.println("b");
factory.getCurrentSession().save(interviewerPojo);
/* System.out.println(interviewerPojo);
template.saveOrUpdate(interviewerPojo);
System.out.println("b");*/
System.out.println("done");
}
}
the same code as above was running if i am getting the values from database as follows
sessionFactory.getCurrentSession().createQuery("select m from emp m).list;
But as I writing another page to insert values then it is having problem
*As you can see i used same concept, I populated MODEL(POJO) class by another MODEL(pojo) which i have taken from database by above query*
and now debugging goes upto "template.saveOrUpdate" and throws exception as follows
