Hi, all There are a lot of JUnit4 tests in flink-table-planner module, but now Jiabao and I have just migrated all tests to JUnit5 through FLINK-29451[1].
Please use JUnit5 tests when submitting new PRs for flink-table-planner module. The opened PRs for flink-table-planner module need to rebase to the latest master. Thanks Jiabao for the huge efforts. Best, Leonard [1]https://issues.apache.org/jira/browse/FLINK-29541
