  @Test public void testNameSetContains() {
    final NameSet names = new NameSet();
    names.add("COUNT");
    names.add("COVAR_POP");
    assertThat(names.contains("count", true), is(false));
    assertNsContains(names, "count", false, true);
  }

  private void assertNsContains(NameSet names, String item, boolean caseSensitive, boolean result) {
    assertEquals(names + ", contains(" + item + (caseSensitive ? ", caseSensitive" : "")
            + ")",
        result, names.contains(item, caseSensitive));
  }
