Review comment:
       For this tests, it's good to simplify it as: 
   
   ```java
   @Test
     public void testMaxContinuousEmptyCommits() throws Exception {
       table.updateProperties()
           .set(IcebergFilesCommitter.MAX_CONTINUOUS_EMPTY_COMMITS, "3")
           .commit();
   
       JobID jobId = new JobID();
       long checkpointId = 0;
       long timestamp = 0;
       try (OneInputStreamOperatorTestHarness<WriteResult, Void> harness = 
createStreamSink(jobId)) {
         harness.setup();
         harness.open();
   
         assertSnapshotSize(0);
   
         for (int i = 1; i <= 9; i++) {
           harness.snapshot(++checkpointId, ++timestamp);
           harness.notifyOfCompletedCheckpoint(checkpointId);
   
           assertSnapshotSize(i / 3);
         }
       }
     }
   ```
