assertEq is showing error when written in the test file foundry

Question

I am writing the test by following the lesson 7 tutorial and got this error, even I imported Test from forge-std
Undeclared identifier. Did you mean "assert"?
this is the actual error

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.18;
import {Test, console} from "forge-std/Test.sol";
import {FundMe} from "../src/FundMe.sol";

contract FundMeTest {
    FundMe fundme;

    function setup() external {
        fundme = new FundMe();
    }

    function checkMminimumDollar() public {
        assertEq(fundme.MINIMUM_USD(), 5e18);
    }
}

Answer 1

You need to inherit the test.sol in your test contract.

Like this :

contract FundMeTest is Test {
    FundMe fundme;

    function setup() external {
        fundme = new FundMe();
    }

    function checkMminimumDollar() public {
        assertEq(fundme.MINIMUM_USD(), 5e18);
    }
}
