### Question:
TimeZoneEncoderImpl implements TimeZoneEncoder { @VisibleForTesting byte[] encodeBias(int biasToEncode) { return intEncoder.capacity(Capacity.FOUR).toByteArray(biasToEncode); } @Inject  TimeZoneEncoderImpl(
			IntEncoder intEncoder, WCHAREncoder wcharEncoder, SystemTimeEncoder systemTimeEncoder); @Override byte[] encode(ASTimeZone asTimeZone);  }### Answer:
@Test public void testEncodeBiasAtZero() { byte[] bias = serializer.encodeBias(0); assertThat(bias).hasSize(SPEC_BIAS_LENGHT).isEqualTo( intEncoder.capacity(Capacity.FOUR).toByteArray(0)); }
@Test public void testEncodeBiasAtPositiveValue() { byte[] bias = serializer.encodeBias(128); assertThat(bias).hasSize(SPEC_BIAS_LENGHT).isEqualTo( intEncoder.capacity(Capacity.FOUR).toByteArray(128)); }
@Test public void testEncodeBiasAtNegativeValue() { byte[] bias = serializer.encodeBias(-128); assertThat(bias).hasSize(SPEC_BIAS_LENGHT).isEqualTo( intEncoder.capacity(Capacity.FOUR).toByteArray(-128)); }
@Test public void testEncodeBiasAtMAXValue() { int maxValue = Integer.MAX_VALUE; byte[] bias = serializer.encodeBias(maxValue); assertThat(bias).hasSize(SPEC_BIAS_LENGHT).isEqualTo( intEncoder.capacity(Capacity.FOUR).toByteArray(maxValue)); }
@Test public void testEncodeBiasAtMINValue() { int minValue = Integer.MIN_VALUE; byte[] bias = serializer.encodeBias(minValue); assertThat(bias).hasSize(SPEC_BIAS_LENGHT).isEqualTo( intEncoder.capacity(Capacity.FOUR).toByteArray(minValue)); }
