### Question:
SystemDataMeta extends BaseTransformMeta implements ITransform { @Override public void loadXml( Node transformNode, IHopMetadataProvider metadataProvider ) throws HopXmlException { readData( transformNode ); } SystemDataMeta(); String[] getFieldName(); void setFieldName( String[] fieldName ); SystemDataTypes[] getFieldType(); void setFieldType( SystemDataTypes[] fieldType ); @Override void loadXml( Node transformNode, IHopMetadataProvider metadataProvider ); void allocate( int count ); @Override Object clone(); @Override void setDefault(); @Override void getFields( IRowMeta row, String name, IRowMeta[] info, TransformMeta nextTransform,
                         IVariables variables, IHopMetadataProvider metadataProvider ); @Override String getXml(); @Override void check( List<ICheckResult> remarks, PipelineMeta pipelineMeta, TransformMeta transformMeta,
                     IRowMeta prev, String[] input, String[] output, IRowMeta info, IVariables variables,
                     IHopMetadataProvider metadataProvider ); @Override ITransform getTransform( TransformMeta transformMeta, ITransformData data, int cnr,
                                PipelineMeta pipelineMeta, Pipeline pipeline ); @Override ITransformData getTransformData(); @Override boolean equals( Object o ); @Override int hashCode();  }### Answer:
@Test public void testLoadXML() throws Exception { SystemDataMeta systemDataMeta = new SystemDataMeta(); DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance(); DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder(); Document document = documentBuilder.parse( new InputSource( new StringReader( expectedXML ) ) ); Node node = document; IHopMetadataProvider store = null; systemDataMeta.loadXml( node, store ); assertEquals( expectedSystemDataMeta, systemDataMeta ); }
