Review Comment:
For more convenient access to those fields from external classes, something
like:
```Java
assertThat(TestingClientHandlerCallback.onRequestCnt).isEqualTo(1);
assertThat(TestingClientHandlerCallback.onRequestId).isEqualTo(1222112277L);
assertThat(TestingClientHandlerCallback.onRequestBody).isInstanceOf(KvStateResponse.class);
```
