How to use

update

method

in

org.springframework.batch.core.step.item.ChunkMonitor

@Test
public void testUpdateOnBoundary() {
  monitor.resetOffset();
  ExecutionContext executionContext = new ExecutionContext();
  monitor.update(executionContext);
  assertEquals(0, executionContext.size());
  executionContext.put(ChunkMonitor.class.getName() + ".OFFSET", 3);
  monitor.update(executionContext);
  assertEquals(0, executionContext.size());
}

@Test
public void testUpdateVanilla() {
  monitor.incrementOffset();
  ExecutionContext executionContext = new ExecutionContext();
  monitor.update(executionContext);
  assertEquals(1, executionContext.size());
}

  @Test
  public void testUpdateWithNoStream() throws Exception {
    monitor = new ChunkMonitor();
    monitor.setItemReader(new ItemReader<String>() {
      @Override
      public String read() throws Exception, UnexpectedInputException, ParseException {
        return "" + (count++);
      }
    });
    monitor.setChunkSize(CHUNK_SIZE);
    monitor.incrementOffset();
    ExecutionContext executionContext = new ExecutionContext();
    monitor.update(executionContext);
    assertEquals(0, executionContext.size());
  }
