### Question:
QueueConfig extends AbstractConfig { public boolean validate() { if (StringUtils.isEmpty(getName())) { log.error("Invalid Queue Configuration : Name must be provided for a queue"); return false; } log.info("Queue configuration validated successfully for queue '{}'", getName()); return true; }  boolean validate(); QueueConfig applyDefaultConfig(QueueConfig defaultQueueConfig); Queue buildQueue(QueueConfig defaultQueueConfig, DeadLetterConfig deadLetterConfig); Queue buildDeadLetterQueue(QueueConfig defaultQueueConfig, DeadLetterConfig deadLetterConfig);  }### Answer:
@Test public void queueConfigWithNameAndValidationSuccessTest() { queueConfig = QueueConfig.builder().name(queueName).build(); assertTrue(queueConfig.validate()); assertThat(outputCapture.toString(), containsString(String.format("Queue configuration validated successfully for queue '%s'", queueName))); }
@Test public void queueConfigWithoutNameAndValidationFailTest() { queueConfig = QueueConfig.builder().build(); assertFalse(queueConfig.validate()); assertThat(outputCapture.toString(), containsString("Invalid Queue Configuration : Name must be provided for a queue")); }
