### Question:
ZoneIdRandomizer extends AbstractRandomizer<ZoneId> { @Override public ZoneId getRandomValue() { List<Map.Entry<String, String>> zoneIds = new ArrayList<>(ZoneId.SHORT_IDS.entrySet()); Map.Entry<String, String> randomZoneId = zoneIds.get(random.nextInt(zoneIds.size())); return ZoneId.of(randomZoneId.getValue()); } ZoneIdRandomizer();  ZoneIdRandomizer(long seed); static ZoneIdRandomizer aNewZoneIdRandomizer(); static ZoneIdRandomizer aNewZoneIdRandomizer(final long seed); @Override ZoneId getRandomValue();  }### Answer:
@Test void generatedValueShouldNotBeNull() { assertThat(randomizer.getRandomValue()).isNotNull(); }
