ERC20Mock File Issue.

[Ritik-Agarwal50]

I am facing this issue while running this Command -

 forge test --match-test testGetusdValue

Error Statements -

The wrong argument count for function call: 4 arguments given but expected 0.
  --> script/HelperConfig.s.sol:55:30:
   |
55 |         ERC20Mock wethMock = new ERC20Mock("WETH", "WETH", msg.sender, 1000e8);
   |                              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Error (6160): Wrong argument count for function call: 4 arguments given but expected 0.
  --> script/HelperConfig.s.sol:62:30:
   |
62 |         ERC20Mock wbtcMock = new ERC20Mock("WBTC", "WBTC", msg.sender, 1000e8);

This Error says I have passed extra arguments but it expect 0 arguments.

Library Which I installed for Openzeppelin

forge install OpenZeppelin/openzeppelin-contracts --no-commit

This is how my ERC20Mock.sol File looks-

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import {ERC20} from "../token/ERC20/ERC20.sol";

contract ERC20Mock is ERC20 {
    constructor() ERC20("ERC20Mock", "E20M") {}

    function mint(address account, uint256 amount) external {
        _mint(account, amount);
    }

    function burn(address account, uint256 amount) external {
        _burn(account, amount);
    }
}
