我需要為我的應(yīng)用程序創(chuàng)建一個集成測試。我使用@SpringBootTest(classes = {Application.class})注釋來啟動它，但它的啟動需要時間。那么當(dāng)我的應(yīng)用程序準(zhǔn)備好時，我如何運(yùn)行測試？問題出在 kafka 偵聽器中：@SpringBootApplicationpublic class Application {   @Autowired   private KafkaConsumeHandler kafkaConsumeHandler;   public static void main(String[] args) {       SpringApplication.run(Application.class, args);   }   @KafkaListener(topics =  "${kafka.topics.test}",  containerFactory = "kafkaListenerContainerFactory")public void listenRegistred(KafkaMessage consumeKafka) {        kafkaConsumeHandler.handleStartProcess(consumeKafka);}如果我嘗試在測試中立即發(fā)送消息，則偵聽器將無法捕捉到它們。所以我在發(fā)送之前使用了一點暫停。@RunWith(SpringRunner.class)@SpringBootTest(classes = {Application.class})@DirtiesContextpublic class ProcessTest {   @ClassRulepublic static KafkaEmbedded embeddedKafka = new KafkaEmbedded(1, true, "testTopic");@Testpublic void sendTestRegistred() throws Exception {    Thread.sleep(5000); // Need a delay to boot an application    ...}
