public void testFilterStringNotIn() throws CommandProcessorException {
    IDriver driver = createDriver();
    String query = "explain select a from t2 where b NOT IN ('XXX', 'UUU') order by a";
    PlanMapper pm = getMapperForQuery(driver, query);
    List<FilterOperator> fos = pm.getAll(FilterOperator.class);
    // the same operator is present 2 times
    fos.sort(TestCounterMapping.OPERATOR_ID_COMPARATOR.reversed());
    assertEquals(1, fos.size());
    FilterOperator fop = fos.get(0);
    // any estimation near 10 is ok...currently 10
    assertEquals(10, fop.getStatistics().getNumRows());
