### Question:
GenericValidatingPackager extends GenericPackager implements ISOValidator { public void setMsgValidator( ISOBaseValidator[] msgVlds ){ this.mvlds = msgVlds; } 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 testSetMsgValidator() throws Throwable { GenericValidatingPackager genericValidatingPackager = new GenericValidatingPackager(); ISOBaseValidator[] msgVlds = new ISOBaseValidator[3]; genericValidatingPackager.setMsgValidator(msgVlds); assertSame(msgVlds, genericValidatingPackager.mvlds, "genericValidatingPackager.mvlds"); }
