### Question:
Convert { public static byte[] toBytes(Object value) { if (value == null) { return null; } else if (value instanceof byte[]) { return (byte[]) value; } else if (value instanceof Blob) { return toBytes((Blob) value); } else { return toString(value).getBytes(); } } private  Convert(); static String toString(Object value); static Boolean toBoolean(Object value); static java.sql.Date toSqlDate(Object value); static java.sql.Date truncateToSqlDate(Object value); static java.sql.Date truncateToSqlDate(long time); static String toIsoString(java.util.Date date); static Double toDouble(Object value); static java.sql.Time toTime(Object value); static java.sql.Timestamp toTimestamp(Object value); static Float toFloat(Object value); static Long toLong(Object value); static Integer toInteger(Object value); static BigDecimal toBigDecimal(Object value); static byte[] toBytes(Object value); static byte[] toBytes(Blob blob); static Short toShort(Object value);  }### Answer:
@Test public void shouldToBytesCovertNull() { the(Convert.toBytes((Object) null)).shouldBeNull(); }
