@Test
public void testDatesToBatchB() {
    BatchInfoPopulationHelperServiceImpl ser = new BatchInfoPopulationHelperServiceImpl();
    Calendar cal = Calendar.getInstance();
    cal.set(2004, Calendar.APRIL, 10);
    Date d = cal.getTime();/*w  w w.j av  a 2s .c  o  m*/

    Collection<Date> dates = new HashSet<>();

    dates.add(d);

    dates.add(DateUtils.addSeconds(d, 3500));// first batch, all within two hours of each other.
    dates.add(DateUtils.addSeconds(d, 7000));// first batch, all within two hours of each other.
    dates.add(DateUtils.addSeconds(d, 8000));// first batch, all within two hours of each other.
    dates.add(DateUtils.addHours(d, 2226));// second batch, but singleton merged backwards

    dates.add(DateUtils.addHours(d, 11124));// third batch , but second was a singleton so we're only on #2.
    dates.add(DateUtils.addHours(d, 11125));// third batch, but gets merged in with second.
    dates.add(DateUtils.addHours(d, 11189)); // fourth batch, but gets merged in with second.

    Map<String, Collection<Date>> actual = ser.convertDatesToBatches(dates);

    /*
     * How many unique values?
     */
    Set<String> s = new HashSet<>(actual.keySet());
    assertEquals(2, s.size());

    this.debug(actual);
