[GitHub] [pulsar] BewareMyPower commented on issue #16509: C++ Flaky-test: ClientTest.testWrongListener
BewareMyPower commented on issue #16509:
URL: https://github.com/apache/pulsar/issues/16509#issuecomment-1179690575
It can be reproduced easily with following command:
```bash
./tests/main --gtest_filter='ClientTest.testWrongListener' --gtest_repeat=10
```
The root cause is the connection could be broken after `ServiceUnitNotReady`, then the next time the topic is subscribed would it fail with `NotConnected` or `ConnectError` before receiving `ServiceUnitNotReady` from broker.
The `ConnectError` case:
