I have tje below mapper, i used services to get entities by code
For the unit tests i mocked these services, but it displays an error java.lang.NullPointerException
@Mapper(uses = { LevelMaturityService.class, SatisfactionLevelService.class })
public interface EvaluationMapper extends EntityMapper<EvaluationDTO, Evaluation> {
@Mapping(source = "levelMaturity.code", target = "levelMaturity", qualifiedByName = { "levelMaturityService", "getLevelMaturityByCode" } )
@Mapping(source = "satisfactionLevel.code", target = "satisfactionLevel", qualifiedByName = { "satisfactionLevelService", "getSatisfactionLevelByCode" })
Evaluation toEntity(EvaluationDTO evaluationDTO);
}
public class EvaluationMapperTest {
private EvaluationMapper evaluationMapper = InstanceMapperConstant.EVALUATION_INSTANCE;
@Mock
private LevelMaturityService levelMaturityService;
@Mock
private SatisfactionLevelService satisfactionLevelService;
private static EvaluationInit evaluationInit;
@BeforeClass
public static void setUp() throws Exception {
evaluationInit = new EvaluationInit();
}
@Test
public void givenEvaluationDTO_thenReturnEvaluation() {
EvaluationDTO evaluationDTO = evaluationInit.buildEvaluationDTOWithId();
when(levelMaturityService.getOne(evaluationDTO.getLevelMaturity().getCode())).thenReturn(Mockito.any(LevelMaturity.class)); // error
when(satisfactionLevelService.getOne(evaluationDTO.getSatisfactionLevel().getCode())).thenReturn(Mockito.any(SatisfactionLevel.class));
Evaluation evaluation = evaluationMapper.toEntity(evaluationDTO);
assertEquals(evaluationDTO.getBusinessValueGroup(), evaluation.getBusinessValueGroup());
}
}
