示例1: testResultOrdering

import org.apache.hadoop.hbase.client.backoff.ExponentialClientBackoffPolicy; //導入方法依賴的package包/類
/**
 * Make sure that we get results in the order that we expect - backoff for a load of 1 should
 * less than backoff for 10, which should be less than that for 50.
 */
@Test
public void testResultOrdering() {
  Configuration conf = new Configuration(false);
  // make the max timeout really high so we get differentiation between load factors
  conf.setLong(ExponentialClientBackoffPolicy.MAX_BACKOFF_KEY, Integer.MAX_VALUE);
  ExponentialClientBackoffPolicy backoff = new ExponentialClientBackoffPolicy(conf);

  ServerStatistics stats = new ServerStatistics();
  long previous = backoff.getBackoffTime(server, regionname, stats);
  for (int i = 1; i <= 100; i++) {
    update(stats, i);
    long next = backoff.getBackoffTime(server, regionname, stats);
    assertTrue(
        "Previous backoff time" + previous + " >= " + next + ", the next backoff time for " +
            "load " + i, previous < next);
