来自主题的春季卡夫卡测试投票记录

Question

我正在使用KafkaTestUtils来获取消费者记录以及其他方便的实用程序进行验证，但是我看到当我打电话给KafkaTestUtils.getSingleRecord(..,...)时似乎从中获取了所有记录。该主题是从其他测试方法（例如：verifyEmptinessErrorMessageInTopic()）发送的，但在assertion方法的getSingleRecord失败，因为计数不是1。在我的实际业务逻辑侦听器中，这是一个手动确认，我执行acknowledgment.acknowledge()来提交偏移量，但是在测试代码中，它似乎从该主题而不是最后一个获取所有记录。我还尝试了consumer.commitsync()，该操作通常执行偏移提交，但效果也不佳。

我在这里是否缺少测试实用程序中的任何配置？感谢您的输入。
