### Question:
DataPacketDto { public String getDataFile() { return dataFile; } DataPacketDto();  DataPacketDto(byte[] data);  DataPacketDto(Map<String, String> attributes, byte[] data);  DataPacketDto(Map<String, String> attributes, String dataFile);  DataPacketDto(Map<String, String> attributes, byte[] data, String dataFile); static Stream<DataPacket> getDataPacketStream(InputStream inputStream); Map<String, String> getAttributes(); void setAttributes(Map<String, String> attributes); byte[] getData(); void setData(byte[] data); String getDataFile(); void setDataFile(String dataFile); DataPacket toDataPacket(); DataPacketDto putAttribute(String key, String value); static final TypeReference<DataPacketDto> DATA_PACKET_DTO_TYPE_REFERENCE; }### Answer:
@Test public void testDataFileConstructor() { String dataFile = "dataFile"; assertEquals(dataFile, new DataPacketDto(null, dataFile).getDataFile()); }
