Icon LinkSetting up test wallets

You'll often want to create one or more test wallets when testing your contracts. Here's how to do it.

Icon LinkCreate a single wallet

	import { Wallet, WalletLocked, WalletUnlocked } from 'fuels';
 
	// use the `generate` helper to make an Unlocked Wallet
	const myWallet: WalletUnlocked = Wallet.generate();
 
	// or use an Address to create a wallet
	const someWallet: WalletLocked = Wallet.fromAddress(myWallet.address);

Icon LinkSetting up multiple test wallets

If you need multiple test wallets, they can be set up as follows:

	import { Provider, bn } from 'fuels';
	import { generateTestWallet } from '@fuel-ts/wallet/test-utils';
	const provider = new Provider('http://127.0.0.1:4000/graphql');
	const assetIdA = '0x0101010101010101010101010101010101010101010101010101010101010101';
	const assetIdB = '0x0202020202020202020202020202020202020202020202020202020202020202';
 
	// single asset
	const walletA = await generateTestWallet(provider, [[42, BaseAssetId]]);
 
	// multiple assets
	const walletB = await generateTestWallet(provider, [
// [Amount, AssetId]
[100, assetIdA],
[200, assetIdB],
[30, BaseAssetId],
	]);
 
	// this wallet has no assets
	const walletC = await generateTestWallet(provider);
 
	// retrieve balances of wallets
	const walletABalances = await walletA.getBalances();
	const walletBBalances = await walletB.getBalances();
	const walletCBalances = await walletC.getBalances();
 
	// validate balances
	expect(walletABalances).toEqual([{ assetId: BaseAssetId, amount: bn(42) }]);
	expect(walletBBalances).toEqual([
{ assetId: BaseAssetId, amount: bn(30) },
{ assetId: assetIdA, amount: bn(100) },
{ assetId: assetIdB, amount: bn(200) },
	]);
	expect(walletCBalances).toEqual([]);
