### Question:
TimeZoneRandomizer extends AbstractRandomizer<TimeZone> { @Override public TimeZone getRandomValue() { String[] timeZoneIds = TimeZone.getAvailableIDs(); return TimeZone.getTimeZone(timeZoneIds[random.nextInt(timeZoneIds.length)]); } TimeZoneRandomizer();  TimeZoneRandomizer(final long seed); static TimeZoneRandomizer aNewTimeZoneRandomizer(); static TimeZoneRandomizer aNewTimeZoneRandomizer(final long seed); @Override TimeZone getRandomValue();  }### Answer:
@Test void generatedValueShouldNotBeNull() { assertThat(randomizer.getRandomValue()).isNotNull(); }
