### Question:
IntegerConverter implements AtlasConverter<Integer> { @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.INTEGER) public Integer toInteger(Integer value) { return value != null ? Integer.valueOf(value) : null; }  @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DECIMAL) BigDecimal toBigDecimal(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.BIG_INTEGER) BigInteger toBigInteger(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.BOOLEAN, concerns = { AtlasConversionConcern.CONVENTION }) Boolean toBoolean(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.BYTE, concerns = AtlasConversionConcern.RANGE) Byte toByte(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.CHAR, concerns = { AtlasConversionConcern.RANGE, AtlasConversionConcern.CONVENTION }) Character toCharacter(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DATE_TIME) Date toDate(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DOUBLE) Double toDouble(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.FLOAT, concerns = AtlasConversionConcern.RANGE) Float toFloat(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.INTEGER) Integer toInteger(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DATE) LocalDate toLocalDate(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.TIME) LocalTime toLocalTime(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DATE_TIME) LocalDateTime toLocalDateTime(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.LONG) Long toLong(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.SHORT, concerns = AtlasConversionConcern.RANGE) Short toShort(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.STRING) String toString(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.NUMBER) Number toNumber(Integer value); @AtlasConversionInfo(sourceType = FieldType.INTEGER, targetType = FieldType.DATE_TIME_TZ) ZonedDateTime toZonedDateTime(Integer value);  }### Answer:
@Test public void convertToInteger() { Integer foo = Integer.MAX_VALUE; Integer out = converter.toInteger(foo); foo++; assertNotNull(out); assertNotSame(out, foo); assertNotEquals(out, foo); }
@Test public void convertToIntegerNull() { Integer out = converter.toInteger(null); assertNull(out); }
