使用Hardhat Ethers.js调用带参数Payable函数报错求助

问题场景 #

Solidity合约代码 #

function Deposit(uint256 StopLoss) public payable {//Deposita quantity i es registre 
        
        //Pay subscription
        if (msg.value == 0){
            revert Quantity_zero();
        }
        //Add wallet to the s_Wallets
        s_Wallets.push(payable(msg.sender));
        //Start subscription time
        Dades storage dades = s_Registre[msg.sender];
        dades.Quantity += msg.value;
        dades.Stop = StopLoss;
    } 

Hardhat测试代码 #

describe("Subscription", async function () {//PriceConversion
            it("Subscribes the deployer", async function () {

              await MarketOrder.Deposit(1850, {value: ethers.utils.parseEther("5")})

              const Quantity = await MarketOrder.CallQuantity()
              console.log(`Q: ${Quantity}`)
              const Stop = await MarketOrder.CallStop()
              console.log(`S: ${Stop}`)
              assert.equal(Quantity.toString(), 1850)
              assert.equal(Stop.toString(), 5)
            }
            })

error Command failed with exit code 1.

错误原因与解决方案 #

1. 参数编码类型不匹配 #

错误提示显示参数编码时BigNumber类型无效，核心原因是uint256类型参数最好显式转换为ethers的BigNumber格式，同时要确保合约函数名大小写完全匹配（Solidity大小写敏感）。

2. 测试断言逻辑完全反转 #

从Solidity代码逻辑可知：

• dades.Quantity存储的是存入的ETH金额（msg.value对应的wei值），而非StopLoss参数1850
• dades.Stop存储的是传入的StopLoss参数1850，而非ETH金额5

修正后的测试代码 #

describe("Subscription", async function () {
    it("Subscribes the deployer", async function () {
        // 显式转换参数为BigNumber，适配Solidity的uint256类型
        const stopLoss = ethers.BigNumber.from(1850);
        const depositAmount = ethers.utils.parseEther("5");

        // 调用payable函数，参数在前，交易选项（value）在后
        await MarketOrder.Deposit(stopLoss, { value: depositAmount });

        const Quantity = await MarketOrder.CallQuantity();
        console.log(`Q: ${Quantity}`);
        const Stop = await MarketOrder.CallStop();
        console.log(`S: ${Stop}`);

        // 修正断言逻辑，匹配合约存储规则
        assert.equal(Quantity.toString(), depositAmount.toString());
        assert.equal(Stop.toString(), stopLoss.toString());
    });
});

额外检查点 #

• 确认合约中Quantity_zero自定义错误已正确声明，避免隐性报错
• 验证CallQuantity和CallStop函数的实现，确保它们正确返回对应存储值
