describe("MyContract", function () {
  it("Should return the correct value", async function () {
    const MyContract = await ethers.getContractFactory("MyContract");
    const contract = await MyContract.deploy();
    await contract.deployed();

    await contract.myFunction();
    expect(await contract.getValue()).to.equal(42);
  });
});

# tests/MyToken.t.sol
pragma solidity ^0.8.0;

import "forge-std/Test.sol";
import "../MyToken.sol";

contract MyTokenTest is Test {
    MyToken public token;

    function setUp() public {
        token = new MyToken(1000000 * 10 ** 18);
    }

    function testInitialSupply() public {
        assertEq(token.totalSupply(), 1000000 * 10 ** 18);
    }

    function testTransfer() public {
        address recipient = address(0x1234);
        uint256 amount = 100 * 10 ** 18;
        token.transfer(recipient, amount);
        assertEq(token.balanceOf(recipient), amount);
    }
}

In this example, we’ve created a simple ERC20 token contract and a corresponding test suite using Foundry’s testing framework. The testInitialSupply function checks if the token’s initial supply is correctly set, while testTransfer verifies that the token transfer functionality works as expected.

    function run() external {
        uint256 initialSupply = 1000000 * 10 ** 18;
        MyToken token = new MyToken(initialSupply);

        address[] memory recipients = new address[](3);
        recipients[0] = address(0x1234);
        recipients[1] = address(0x5678);
        recipients[2] = address(0x9012);

        uint256[] memory amounts = new uint256[](3);
        amounts[0] = 100 * 10 ** 18;
        amounts[1] = 200 * 10 ** 18;
        amounts[2] = 300 * 10 ** 18;

        for (uint256 i = 0; i < recipients.length; i++) {
            token.transfer(recipients[i], amounts[i]);
        }
    }
}

To execute this script, you can run the following command:

1
forge script script/DeployToken.s.sol --broadcast

This will compile the contracts, deploy the MyToken contract with an initial supply, and then transfer tokens to the specified recipients.

contract MyContract {
    uint256 public value;

    function setValue(uint256 _value) public {
        value = _value;
    }
}

// Foundry test
import "forge-std/Test.sol";

contract MyContractTest is Test {
    MyContract public myContract;

    function setUp() public {
        myContract = new MyContract();
    }

    function testSetValue() public {
        myContract.setValue(42);
        assertEq(myContract.value(), 42);
    }
}

In this example, we have a simple MyContract that allows setting a value. The MyContractTest contract demonstrates how Foundry’s testing framework can be used to write unit tests for smart contracts. The setUp function initializes the contract instance, and the testSetValue function tests the setValue function by asserting the expected value.

Foundry’s community has also contributed to various ecosystem projects, such as libraries, tools, and plugins, that extend Foundry’s functionality. For instance, the forge-fmt project provides a code formatter for Solidity contracts, ensuring consistent code style across projects.

from brownie import MyContract, accounts

def main():
    deployer = accounts[0]
    contract = MyContract.deploy({"from": deployer})
    print(f"Contract deployed at: {contract.address}")

The Python code snippet above demonstrates how Foundry can be integrated with other tools and frameworks, such as Brownie. In this example, we use Brownie to deploy the MyContract contract to the Ethereum network using the first account from the accounts list.
