keranbingaa opened a new issue #1528: unit test of DefaultMQProducer has some problems when send async messages
URL: https://github.com/apache/rocketmq/issues/1528
 
 
   **BUG REPORT**
   
   1. Please describe the issue you observed:
   in DefaultMQProducerTest, the async mode test doesn't execute as expected. 
   For example, the testSendMessageAsync_Success function call send function, which is expected to excute callback function onSuccess, but when I debug, I find it calls onException.
   
   2. Please tell us about your environment:
   rocketMQ 4.5
   
   3. Other information (e.g. detailed explanation, logs, related issues, suggestions how to fix, etc):
   when producer get the topicrouteinfo, it returns null, which causes this problem. So if the producer get right topicrouteinfo and call sendback function, it canbe excuted as we expected.
