Advanced Example

A more complex example showcasing genesis block state configuration with walletsConfig and deployment of multiple contracts is shown below.

const assets = TestAssetId.random(2);
const message = new TestMessage({ amount: 1000 });

using counterContractNode = await launchTestNode({
  walletsConfig: {
    count: 4,
    assets,
    coinsPerAsset: 2,
    amountPerCoin: 1_000_000,
    messages: [message],
  },
  contractsConfigs: [
    {
      factory: CounterFactory,
      walletIndex: 3,
      options: { storageSlots: [] },
    },
  ],
});

const {
  contracts: [counterContract],
  wallets: [wallet1, wallet2, wallet3, wallet4],
} = counterContractNode;

console.assert(
  counterContract instanceof CounterFactory,
  'CounterFactory is not instance of CounterFactory'
);
console.assert(wallet1 instanceof WalletUnlocked, 'Wallet1 is not instance of WalletUnlocked');
console.assert(wallet2 instanceof WalletUnlocked, 'Wallet2 is not instance of WalletUnlocked');
console.assert(wallet3 instanceof WalletUnlocked, 'Wallet3 is not instance of WalletUnlocked');
console.assert(wallet4 instanceof WalletUnlocked, 'Wallet4 is not instance of WalletUnlocked');

Summary

1. All points listed in the basic example apply here as well.
2. Multiple wallets were generated with highly-specific coins and messages.
3. It's possible to specify the wallet to be used for contract deployment via walletIndex.
4. The test contract can be deployed with all the options available for real contract deployment.
