@Repository
public interface UserRepository extends JpaRepository<User, Long>

public interface JpaRepository<T, ID>

    @Test
    @DisplayName("getAllNotifications: user = userRepository.getById(user_id) : True -> ThrowClassCastException")
    public void testGetAllNotifications_ThrowClassCastException() {
        byte[] byteArray = {};
        (when(userRepositoryMock.getById(any()))).thenReturn(byteArray);
        
        /* This test fails because method [com.app.medicalwebapp.services.NotificationService.getAllNotifications] produces [java.lang.ClassCastException: class [B cannot be cast to class com.app.medicalwebapp.model.User ([B is in module java.base of loader 'bootstrap'; com.app.medicalwebapp.model.User is in unnamed module of loader org.utbot.instrumentation.process.HandlerClassesLoader @10eb7238)]
