java.lang.IllegalStateException: Failed to load ApplicationContext error while running maven install

Question

Below is my DTO class:

@Entity
@Data
@Table(name = "carservice")
public class CarService {

//  public static void main(String[] args) {
        
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO) 
        long serviceCode;

        @Column(name = "service")
        private String service;
        
        @Column(name = "hatchback")
        private String hatchback;
        
        @Column(name = "sedan")
        private String sedan;
        
        @Column(name = "suv")
        private String suv;

        
        
        public CarService(long serviceCode, String service, String hatchback, String sedan, String suv) {
            super();
            this.serviceCode = serviceCode;
            this.service = service;
            this.hatchback = hatchback;
            this.sedan = sedan;
            this.suv = suv;
        }

        public long getServiceCode() {
            return serviceCode;
        }

        public void setServiceCode(long serviceCode) {
            this.serviceCode = serviceCode;
        }

        public String getService() {
            return service;
        }

        public void setService(String service) {
            this.service = service;
        }

        public String getHatchback() {
            return hatchback;
        }

        public void setHatchback(String hatchback) {
            this.hatchback = hatchback;
        }

        public String getSedan() {
            return sedan;
        }

        public void setSedan(String sedan) {
            this.sedan = sedan;
        }
.....

My controller is as follows:

@CrossOrigin(origins = "http://localhost:8081")
@RestController
@RequestMapping("/api")
public class CarServiceController {

    @Autowired
    CarServiceRepository CarServiceRepository;

    @GetMapping("/CarServices/{id}")
    public ResponseEntity<CarService> getCarServiceById(@PathVariable("id") long id) {
        List<CarService> CarServiceData = CarServiceRepository.findByServiceCode(id);

        if (CarServiceData!=null) {
            return new ResponseEntity<>(CarServiceData.get(0), HttpStatus.OK);
        } else {
            return new ResponseEntity<>(HttpStatus.NOT_FOUND);
        }
    }

    

}

And the repository class is as follows:

@Repository
public interface CarServiceRepository extends JpaRepository<CarService, Long> {
     
    @Query(value = "SELECT * FROM CARSERVICE", nativeQuery = true)
    List<CarService> findByServiceCode(Long id);

//  List<CarService> findByTitleContaining(Long id);
      
    }

When I am running the maven install command , the tests are failing and the error in surefire-reports are as follows:
