Motivation
Some unit tests modify the global conf, but do not restore it, which will affect other unit tests.For example: restricted frequency
TopicDuplicationTest.testTopicPolicyTakeSnapshot: The interval of this unit test has been increased
. If the interval is too short, it cannot be completed within the specified interval when the broker is busy. After the modification, call the test 500 times without any exception.
ConsumedLedgersTrimTest: Did not clean up
Modifications
add resetConfig() or restore config
