> Key: FLINK-30815
> URL: https://issues.apache.org/jira/browse/FLINK-30815
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.16.0
> Reporter: Zhu Zhu
> Assignee: Yuxin Tan
> Priority: Major
> Labels: pull-request-available
>
> BatchTestBase/BatchAbstractTestBase are using Junit4, while some child tests
> (e.g. DynamicFilteringITCase) are using JUnit5. This may break some
> assumption and hide some problems.
> For example, the child test will create a MiniCluster by itself, instead of
> using the MiniCluster(TM=1, slots=3) created in BatchAbstractTestBase. The
> created MiniCluster may have more slots and hide resource deadlock issues.
