在Foundry测试期间如何将msg.value发送到solidity中的payable func？

Question

我的合约代码

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

import {CarNFT} from "./CarNFT.sol";
// OrderManager contract

contract OrderManager {
    ... code

    function deposit() external payable onlyBuyer {
        // Buyer deposits funds
        require(msg.value == price, "Incorrect deposit amount");
    }

}

OrderManger.t.sol 测试文件

function testDeposit() public {
        // Assuming startPrank, deal, and stopPrank functions work as expected
        vm.startPrank(buyer);
        vm.deal(buyer, 10 ether);

        // Ensure the buyer has the expected balance
        uint256 buyerBalanceBefore = address(buyer).balance;
        assertEq(buyerBalanceBefore, 10 ether);

        // Deposit into OrderManager contract
        orderM.deposit();

        // Ensure the balance of the OrderManager contract is updated
        uint256 contractBalance = orderM.getBalance();
        emit log_named_uint("Contract's balance is", contractBalance);
        assertEq(price, contractBalance);

        // Ensure the buyer's balance has been reduced by the deposited amount
        uint256 buyerBalanceAfter = address(buyer).balance;
        emit log_named_uint("Buyer's balance after deposit is", buyerBalanceAfter);
        assertEq(buyerBalanceBefore - price, buyerBalanceAfter);

        vm.stopPrank();
    }

如果我想通过 msg.send 在 calldata 中发送 ETH，我该使用什么语法？

我使用 Foundry 作为开发工具；我应该为此目的使用 Foundry 作弊代码吗？

请指导

Answer 1

这里正确的语法是

orderM.deposit{value: 0.2 ether}()

或者一般情况下

contractInstance.func{value: msg.sender (value in ether or wei; see below)}(func args)

如果在Foundry中msg.send可以指定为（0.2 ether），否则以wei（200000000000000000）发送
