private void doTestCommaDelimitedListToStringArrayLegalMatch(String[] components) {
  StringBuilder sb = new StringBuilder();
  for (int i = 0; i < components.length; i++) {
    if (i != 0) {
      sb.append(",");
    }
    sb.append(components[i]);
  }
  String[] sa = StringUtils.commaDelimitedListToStringArray(sb.toString());
  assertTrue("String array isn't null with legal match", sa != null);
  assertEquals("String array length is correct with legal match", components.length, sa.length);
  assertTrue("Output equals input", Arrays.equals(sa, components));
}
