Piotr Nowojski closed FLINK-11397.
----------------------------------
Resolution: Cannot Reproduce
I'm closing this issue, since there is no known performance issue in
{{AbstractStreamOperatorTestHarness}}.
> Speed up initialization of AbstractStreamOperatorTestHarness
> ------------------------------------------------------------

> Key: FLINK-11397
> URL: https://issues.apache.org/jira/browse/FLINK-11397
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream, Tests
> Affects Versions: 1.8.0
> Reporter: TisonKun
> Priority: Major
>
> Currently Kafka connector tests are unbearably slow, which is tracked by
> FLINK-10603. With investigation, the construction and initialization of
> {{AbstractStreamOperatorTestHarness}} is quite slow.
> -When walk down the code, it amazed me that {{mockTask =
> mock(StreamTask.class);}} cost a few of second to finish. If we can introduce
> a test class instead of mock framework, the situation might be loosen.-
