Ich bin neu in Mockito und versuche, meine Service-Schicht zu testen. Meine DAO-Schicht ist @Autowired im Dienst und Hibernate ist auch autowired. Hibernate wird während des Tests nicht geladen. Ich bekomme immer NullPointerException. Hier ist mein Code:Mockito Test Service Schicht
EmployeeService (Interface)
package com.spring.crud.service;
import java.util.List;
import com.spring.crud.entity.Employee;
public interface EmployeeService {
Employee save(Employee employee);
boolean update(Employee employee);
Employee find(Integer id);
List<Employee> getEmployees();
boolean remove(Integer id);
}
EmployeeServiceImpl (Klasse)
package com.spring.crud.service;
import java.util.List;

}
public boolean update(Employee employee) {

}
public Employee find(Integer id) {

}
public List<Employee> getEmployees() {

}
public boolean remove(Integer id) {
return dao.remove(id);
}
}
EmployeeDAO (Interface)
package com.spring.crud.dao;
import java.util.List;

public interface EmployeeDAO {

EmployeeDAOImpl (Klasse)

session.update(employee);

Session session = getCurrentSession();
Employee employee = (Employee)session.get(Employee.class, id);

@SuppressWarnings("unchecked")
List<Employee> employees = (List<Employee>)query.list();

Session session = getCurrentSession();
Employee employee = (Employee)session.get(Employee.class, id);
if(employee!=null){
session.delete(employee);
return true;
}
return false;
}
}
HibernateUtil

Ich kann nicht viel über diese im Internet finden.
