current ParaTokens::deposit(KAR, &AccountId::from(ALICE), 2000 * dollar(KAR)) have ExistentialDeposits limitation.
so I use KUSD instead.


KusamaNet::execute_with(|| {
let xcm = vec![
WithdrawAsset(assets.clone().into()),
BuyExecution {
fees: assets,
weight_limit: Limited(dollar(KSM) as u64),
},
Transact {
origin_type: OriginKind::SovereignAccount,
require_weight_at_most: (dollar(KSM) as u64) / 10 as u64,
call: call.encode().into(),
},
];
assert_ok!(RelayChainPalletXcm::send_xcm(alice, Parachain(2000).into(), Xcm(xcm),));
});

Karura::execute_with(|| {
use {Event, System};
assert_eq!(9 * dollar(KAR), ParaTokens::free_balance(KSM, &AccountId::from(ALICE)));
assert_eq!(500 * dollar(KAR), ParaBalances::free_balance(&AccountId::from(ALICE)));
assert_eq!(500 * dollar(KAR), ParaBalances::free_balance(&AccountId::from(BOB)));
System::assert_has_event(Event::Balances(pallet_balances::Event::Transfer(
AccountId::from(ALICE),
AccountId::from(BOB),
500 * dollar(KAR),
)));
});
