### Question:
GenericValidatingPackager extends GenericPackager implements ISOValidator { public void setFieldValidator( ISOFieldValidator[] fvlds ){ this.fvlds = fvlds; } GenericValidatingPackager(  );  GenericValidatingPackager( String fileName );  GenericValidatingPackager(InputStream stream); void readFile(String filename); void setMsgValidator( ISOBaseValidator[] msgVlds ); void setFieldValidator( ISOFieldValidator[] fvlds ); ISOComponent validate(ISOComponent m);  }### Answer:
@Test public void testSetFieldValidator() throws Throwable { GenericValidatingPackager genericValidatingPackager = new GenericValidatingPackager(); ISOFieldValidator[] fvlds = new ISOFieldValidator[1]; genericValidatingPackager.setFieldValidator(fvlds); assertSame(fvlds, genericValidatingPackager.fvlds, "genericValidatingPackager.fvlds"); }
