zl commented on FLINK-28404:
----------------------------
For example, ReactiveModeITCase use {{RestClusterClient}} to get job details,
See
[ReactiveModeITCase.java#L202|https://github.com/apache/flink/blob/a89152713aa58647841c46ed2335b45d24c553f9/flink-tests/src/test/java/org/apache/flink/test/scheduling/ReactiveModeITCase.java#L202].
when we port ReactiveModeITCase to junit5, we would need inject
{{RestClusterClient.}}
And [MiniClusterExtension.java#L107
|https://github.com/apache/flink/blob/master/flink-test-utils-parent/flink-test-utils/src/main/java/org/apache/flink/test/junit5/MiniClusterExtension.java#L107]provides
an example about how to inject RestClusterClient, but it does not work well.
> Annotation @InjectClusterClient does not work correctly with RestClusterClient
