### Question:
AtlasXmlModelFactory { public static XmlDocument createXmlDocument() { XmlDocument xmlDocument = new XmlDocument(); xmlDocument.setFields(new Fields()); return xmlDocument; }  static XmlDocument createXmlDocument(); static XmlField createXmlField(); static XmlField cloneField(XmlField field, boolean withActions); static FieldGroup cloneFieldGroup(FieldGroup group); static void copyField(Field from, Field to, boolean withActions); static final String URI_FORMAT; }### Answer:
@Test public void testCreateXmlDocument() { XmlDocument xmlDoc = AtlasXmlModelFactory.createXmlDocument(); assertNotNull(xmlDoc); assertNotNull(xmlDoc.getFields()); assertNotNull(xmlDoc.getFields().getField()); assertEquals(new Integer(0), new Integer(xmlDoc.getFields().getField().size())); }
