### Question:
IsochronesRequestHandler extends GenericHandler { String[] convertAttributes(IsochronesRequestEnums.Attributes[] attributes) { return convertAPIEnumListToStrings(attributes); } IsochronesRequestHandler(); void generateIsochronesFromRequest(IsochronesRequest request); IsochroneMapCollection getIsoMaps(); IsochroneRequest getIsochroneRequest();  }### Answer:
@Test public void convertAttributes() { IsochronesRequestEnums.Attributes[] atts = new IsochronesRequestEnums.Attributes[]{IsochronesRequestEnums.Attributes.AREA, IsochronesRequestEnums.Attributes.REACH_FACTOR, IsochronesRequestEnums.Attributes.TOTAL_POPULATION}; String[] attStr = handler.convertAttributes(atts); Assert.assertEquals("area", attStr[0]); Assert.assertEquals("reachfactor", attStr[1]); Assert.assertEquals("total_pop", attStr[2]); }
