Насмешка над автопроводным объектом базового абстрактного класса

0 голосов
/ 22 марта 2019

Я пишу тестовый пример Junit для класса, который расширен абстрактным классом. Этот базовый абстрактный класс имеет объект с автоподстройкой другого класса, который используется в классе, который я тестирую. Я пытаюсь смоделировать в подклассе, но смоделированный объект выбрасывает исключение NullPointerException.

Пример: 

// class I am testing
public class GetTransactionsForProcessorGroupActivity extends GetTransactionsBaseActivity {

    private static final Logger log = LogManager.getLogger(GetTransactionsForProcessorGroupActivity.class);

    public GetTransactionsForProcessorGroupActivity(ARHFactory arhFactory, MetricsFactory metricsFactory) {
        super(arhFactory, metricsFactory);
    }


    @Override
    protected List<OverseasTransaction> getOverseasTransactions(Document herdDocument)
            throws IllegalDateFormatException, ProcessorConfigurationException, DocumentException {
        final String paymentProcessorGroup = HerdDocumentUtils.getPaymentProcessor(herdDocument);
        final Date runDate = HerdDocumentUtils.getRunDate(herdDocument);

        final List<String> paymentProcessorList = ProcessorGroupLookup.getProcessorsFromGroup(paymentProcessorGroup);
        List<OverseasTransaction> overseasTransactionList = new ArrayList<OverseasTransaction>();
        List<ProcessorTransactionWindow> processingWindows = new ArrayList<ProcessorTransactionWindow>();

        for (final String processor : paymentProcessorList) {
            ProcessorTransactionWindow transactionWindow = ProcessorCalendarUtils.getProcessorTransactionWindow(processor, runDate);
            processingWindows.add(transactionWindow);

            final Date processingFromDate = transactionWindow.getFromDate();
            final Date processingToDate = transactionWindow.getToDate();
//NullpointerException on this line, as OverseasTransactionStore mock object returns null.
            final List<OverseasTransaction> transactions = overseasTransactionsStore
                    .queryOverseasTransactionsOnPPTimelineandDates(processor, processingFromDate, processingToDate);
            overseasTransactionList.addAll(transactions);
        }

        HerdDocumentUtils.putProcessingWindowDetails(herdDocument, processingWindows);
        return overseasTransactionList;
    }

}

}

В моем тестовом файле, когда я высмеиваю объект OverseasTransaction, он дает мне исключение NullPointerException. Есть ли у вас какие-либо предложения о том, как мы можем посмеяться над этим? Все приведенные выше строки комментариев в моем тесте указывают на то, что я пробовал, но они все равно, кажется, выдают ту же ошибку.

Вам нужно создать объект Class, для которого вы пишете тест.т.е. GetTransactionsForProcessorGroupActivity.Есть то, что вы можете сделать 

@RunWith(MockitoJUnitRunner.class)
public class GetTransactionsForProcessorGroupActivityTest {

  @InjectMocks
  private GetTransactionsForProcessorGroupActivity getTransactionsForProcessorGroupActivity;

  @Mock
  private OverseasTransaction overseastransaction;

  @Test
  public void test() {
    Mockito.when(overseastransaction.somemethod()).thenReturn(something);
  }
}

Это будет гарантировать, что getTransactionsForProcessorGroupActivity будет создан, а в заграничную транзакцию введен фиктивный объект.

Обратите внимание на аннотацию класса @ RunWith .Это гарантирует, что все свойства введены с фиктивным объектом правильно.Также вы можете использовать Mockito вместо PowerMockito.
