google app engine - Objectify transaction fails in unit test -

-

this unit test of simple objectify transaction fail on: "transactions on multiple entity groups allowed in high replication applications". whenever there 1 entity used in case. such transaction executed on both dev server , google instance. need localservicetesthelper tweaking. can please?

here unit test:

@test public void transactiontest() {     // setup     final localservicetesthelper helper = new localservicetesthelper(             new localdatastoreservicetestconfig(),             new localmemcacheservicetestconfig());           helper.setup();     closeable session = objectifyservice.begin();      // test     ofy().transactnew(new voidwork() {         @override         public void vrun() {             user user = new user();             ofy().save().entity(user).now();         }     });      // teardown     helper.teardown();     session.close();     session = null; }

and here exception get:

you must explicitly enable hrd - bit odd today since master/slave datastore no longer exists:

private final localservicetesthelper helper =         new localservicetesthelper(                 new localdatastoreservicetestconfig().setapplyallhighrepjobpolicy());
