question: public static Object run ( String rule , Map < String , Object > variables , Context context ) { StellarProcessor processor = new StellarProcessor ( ) ; Assert . assertTrue ( rule + " not valid." , processor . validate ( rule , context ) ) ; Object ret = processor . parse ( rule , null , StellarFunctions . FUNCTION_RESOLVER ( ) , context ) ; byte [ ] raw = SerDeUtils . toBytes ( ret ) ; Object actual = SerDeUtils . fromBytes ( raw , Object . class ) ; Assert . assertEquals ( ret , actual ) ; return ret ; }
target:  This ensures the basic contract of a stellar expression is adhered to: 1. Validate works on the expression 2. The output can be serialized and deserialized properly
