使用truffle在构造函数中使用参数测试智能合约

pragma solidity ^0.8.0;

contract MyContract {
    uint256 public value;

    constructor(uint256 _value) {
        value = _value;
    }

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

const MyContract = artifacts.require("MyContract");

contract("MyContract", accounts => {
    it("should set the initial value correctly", async () => {
        const instance = await MyContract.new(100);
        const value = await instance.value();
        assert.equal(value.toNumber(), 100, "Initial value should be 100");
    });

    it("should update the value correctly", async () => {
        const instance = await MyContract.new(100);
        await instance.setValue(200);
        const value = await instance.value();
        assert.equal(value.toNumber(), 200, "Value should be updated to 200");
    });
});

const instance = await MyContract.new(100); // 确保传递正确的参数

constructor(uint256 _value) {
    value = _value;
}
