我在线上找到了一些教程，并在Stackoverflow上找到了一些资源，但是我无法将该逻辑转换为应用程序。我是Junit testing的新手。我有3个课程，User，UserServiceH2和UserController
用户类别
@Id
@GeneratedValue
private int id;
@Column(name = "username")
private String username; //username of the user
@Column(name = "first_name")
private String firstname; //first name of the user
@Column(name = "last_name")
private String lastname; //last name of the user
@Column(name = "doj")
private Date dateOfJoining; //date of joining of the user
/** This is the getter method for username of the user.using this we can get user's username
*
* @return string
*/
public String getUsername() {
return username;
}
/** This is the setter method for username of the user. We can set the user's username
*
* @return void
*/
public void setUsername(String username) {
this.username = username;
}
/** We can get the first name of the user.
*
* @return string
*/
public String getFirstname() {
return firstname;
}
/** We can set the user's first name
*
* @return void
*/
public void setFirstname(String firstname) {
this.firstname = firstname;
}
/** We can get the user's last name
*
* @return string
*/
public String getLastname() {
return lastname;
}
/** We can set the last name of the user
*
* @return void
*/
public void setLastname(String lastname) {
this.lastname = lastname;
}
/** We can get joining date of user
*
* @return Date
*/
public Date getDateOfJoining() {
return dateOfJoining;
}
/** We can set joining date of user
*
* @return void
*/
public void setDateOfJoining(Date dateOfJoining) {
this.dateOfJoining = dateOfJoining;
}
UserController
/**
* creating user into database
* @param
*/
public void createUser() {
User user = new User();
UserServiceH2 serviceH2 = new UserServiceH2();
serviceH2.createUser(user);
}
/**
* retrieving all the instances from database
* @return
*/
public void getAllUsers() {
UserServiceH2 serviceH2 = new UserServiceH2();
List<User> allUsers = serviceH2.getAllUsers();
for(int i = 0; i < allUsers.size(); i++) {
System.out.println( allUsers.get(i)
);
}
}
/**
* Retrieve a resource based on id and update its firstname, lastname or username
* @param
*/
public void updateUser() {
User user = new User();
UserServiceH2 serviceH2 = new UserServiceH2();
serviceH2.updateUser(user);
}
/**
* delete a resource from database based on given id
* @param
*/
public void deleteUser() {
User user = new User();
UserServiceH2 serviceH2 = new UserServiceH2();
serviceH2.deleteUser(user);
}
UserServiceH2
/**
* creating user into database
* @param
*/
public void createUser(User u) {
//setting values for user
u.setFirstname("Qasim");
u.setLastname("Ali");
u.setUsername("DjBravo");
u.setDateOfJoining(new Date());
SpecialUser specialUser = new SpecialUser();
specialUser.setSpecialDiscount(50.00);
//object of student user
StudentUser studentUser = new StudentUser();
studentUser.setUniversity("University of Bolzano");
SessionFactory sessionFactory = new Configuration().configure().addAnnotatedClass(User.class).buildSessionFactory();
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
session.save(u);
session.save(specialUser);
session.save(studentUser);
session.getTransaction().commit();
session.close();
}
/**
* retrieving all the instances from database
* @return List
*/
public List<User> getAllUsers() {
SessionFactory sessionFactory = new Configuration().configure().addAnnotatedClass(User.class).buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
//retrieve all the user instances from database
List<User> users = session.createQuery("FROM User").list();
return users;
}
/**
* Retrieve a resource based on id and update its firstname, lastname or username
* @param u
*/
public void updateUser(User u) {
int userId = 2;
SessionFactory sessionFactory = new Configuration().configure().addAnnotatedClass(User.class).buildSessionFactory();
//now get a new session and start transaction
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
//retrieve student based on the id
System.out.println("\n Getting Student with id " + userId);
User myUser = session.get(User.class, userId);
System.out.println("Updating Student ");
myUser.setUsername("Sarfraz");
//commit the transaction
session.getTransaction().commit();
System.out.println("Done");
session.close();
}
/**
* delete a resource from database based on given id
* @param u
*/
public void deleteUser(User u) {
int userId = 6;
SessionFactory sessionFactory = new Configuration().configure().addAnnotatedClass(User.class).buildSessionFactory();
//now get a new session and start transaction
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
//retrieve student based on the id
System.out.println("\n Getting Student with id " + userId);
User myUser = session.get(User.class, userId);
//delete student
System.out.println("Deleting Student " + myUser);
session.delete(myUser);
//commit the transaction
session.getTransaction().commit();
System.out.println("Done");
session.close();
}
请确定错误的做法并告诉最佳做法。我该如何为Junit testing
TestUserController
@Test
void createUser(User user) {
user.setUsername("Oscar");
user.setFirstname("Darren");
user.setLastname("Sammy");
user.setDateOfJoining(new Date());
SessionFactory sessionFactory = new Configuration().configure().addAnnotatedClass(User.class).buildSessionFactory();
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
session.save(user);
assertEquals(1,);
}
@Test
void getAllUsers() {
}
@Test
void updateUser() {
}
@Test
void deleteUser() {
}
