Question

在执行单元测试期间，该方法被调用3次。每次使用不同的参数调用它。我想验证，最后一次使用相应的参数调用方法。

请帮助我。

我的方法：

private void doHandle(Updategram updategram)
      throws FixtureNotFoundException, DatatypeConfigurationException {
    BetSyncObject betSyncObject = transformer.transformer(updategram);
    EventTreeCreation event = betSyncObject.eventTree;
    if (!event.getEvent().isEmpty()) {
      Event event2 = event.getEvent().get(0);
      long timestamp =
          updategram.getHeader().getTimeStampUtc().toGregorianCalendar().getTimeInMillis();
      String sportName = event2.getSportcode();
      String id = event2.getExtId();
      publisher.publishEvent(PROVIDER_NAME, betSyncObject, sportName, id, timestamp);
    } else {
      LOGGER.info("Empty event tree : {}", betSyncObject);
    }
  }

测试：

 @Test
    public void testCountAndSetResultLine() throws Exception{
        EventPublisher eventPublisher = Mockito.mock(EventPublisher.class);
        BetgeniusService betgeniusService = new BetgeniusService();

        BetSyncObject expectedBetSyncObj = transformer.transformer(updategram);

        ExecutorService service = Executors.newFixedThreadPool(3);
        handle(betgeniusService, updategramFixture, service);
        Thread.sleep(50);
        handle(betgeniusService, updategramMarketSet, service);
        Thread.sleep(50);
        handle(betgeniusService, updategramResult, service);

        service.shutdown();
        service.awaitTermination(20000, TimeUnit.MILLISECONDS);
        betgeniusService.getExecutor().shutdown();
        betgeniusService.getExecutor().awaitTermination(20000, TimeUnit.MILLISECONDS);

        Mockito.verify(eventPublisher, Mockito.times(3)).publishEvent(Mockito.anyString(), Mockito.any(BetSyncObject.class),
                Mockito.anyString(), Mockito.anyString(), Mockito.anyLong());

    }

目前我正在获得异常，因为publishEvent方法未被调用3次，而expectedBetSyncObj正好被调用。应该只在最后一次调用它。

那么，请告诉我如何检查最后一次使用publishEvent对象调用expectedBetSyncObj方法。

我认为你可以通过ArgumentCaptor实现这一目标。使用ArgumentCaptor获取所有调用的参数，然后验证它们中的每一个。在您的情况下，您将验证在第三次调用时，参数（.get(2)）是预期的对象。

类似

ArgumentCaptor<BetSyncObject> betSyncObjectCaptor = ArgumentCaptor.forClass(BetSyncObject.class);
Mockito.verify(eventPublisher, Mockito.times(3)).publishEvent(Mockito.anyString(), betSyncObjectCaptor.capture(), Mockito.anyString(), Mockito.anyString(), Mockito.anyLong());

List<BetSyncObject> capturedBetSyncObject = betSyncObjectCaptor.getAllValues();
assertEquals(expectedBetSyncObj, capturedBetSyncObject.get(2));

Mockito，如何在上次调用时验证ther方法的参数
