### Question:
LongConverter implements AtlasConverter<Long> { @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.BOOLEAN, concerns = AtlasConversionConcern.CONVENTION) public Boolean toBoolean(Long value) { if (value == null) { return null; } return value == 0L ? Boolean.FALSE : Boolean.TRUE; }  @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DECIMAL) BigDecimal toBigDecimal(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.BIG_INTEGER) BigInteger toBigInteger(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.BOOLEAN, concerns = AtlasConversionConcern.CONVENTION) Boolean toBoolean(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.BYTE, concerns = AtlasConversionConcern.RANGE) Byte toByte(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.CHAR, concerns = { AtlasConversionConcern.RANGE, AtlasConversionConcern.CONVENTION }) Character toCharacter(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DATE_TIME_TZ) Date toDate(Long date); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DOUBLE) Double toDouble(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.FLOAT) Float toFloat(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.INTEGER, concerns = AtlasConversionConcern.RANGE) Integer toInteger(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DATE) LocalDate toLocalDate(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.TIME) LocalTime toLocalTime(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DATE_TIME) LocalDateTime toLocalDateTime(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.LONG) Long toLong(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.SHORT, concerns = AtlasConversionConcern.RANGE) Short toShort(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.NUMBER) Number toNumber(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.STRING) String toString(Long value); @AtlasConversionInfo(sourceType = FieldType.LONG, targetType = FieldType.DATE_TIME_TZ) ZonedDateTime toZonedDateTime(Long value);  }### Answer:
@Test public void convertToBoolean() { Long aLong = 0L; Long l = 1L; Boolean b = converter.toBoolean(l); assertNotNull(b); assertTrue(b); b = converter.toBoolean(aLong); assertNotNull(b); assertFalse(b); }
@Test public void convertToBooleanNull() { Long l = null; Boolean b = converter.toBoolean(l); assertNull(b); }
@Test public void convertToBooleanNegative() { Long dt = -1L; Boolean b = converter.toBoolean(dt); assertTrue(b); }
