Displaying contract address instead of contract name in Terminal

[chainflash]

When Patrick checks the error in the terminal it shows the contract name like this:

VRFCoordinatorV2_5Mock::addConsumer

but for me only the contract address is displayed and I have to manually look up the name for this address:

0x9DdfaCa8183c41ad55329BdeeD9F6A8d53168B1B::addConsumer

I tried:
Adding include_contract_names = true in foundry.toml
running forge clean && forge build
testing with forge test --fork-url $SEPOLIA_RPC_URL -vvvvv
running foundryup
But the issue persists. Any solutions?

@chainflash I guess you can see the names if you just run forge test -vvvv. When you run tests using a fork, Foundry doesn't have access to the local artifacts for contracts that weren't deployed from your project. Foundry relies on metadata from locally deployed contracts to map addresses to names. If you interact with a contract that was already deployed on the remote network (even though you have its source locally), Foundry won’t have the local deployment metadata and will only display the address. To get human-friendly contract names when forking you could do something like this for example.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.19;

import {Test} from "forge-std/Test.sol";
import {VRFCoordinatorV2_5Mock} from "@chainlink/contracts/src/v0.8/vrf/mocks/VRFCoordinatorV2_5Mock.sol";
import {CodeConstants} from "script/HelperConfig.s.sol";

contract ContractForkTest is Test, CodeConstants {
    VRFCoordinatorV2_5Mock public coordinator;

    function setUp() public {
        // Deploy the contract locally on the forked chain
        coordinator = new VRFCoordinatorV2_5Mock(MOCK_BASE_FEE, MOCK_GAS_PRICE_LINK, MOCK_WEI_PER_UNIT_LINK);
    }

    function testExample() public {
        // Interact with your contract as usual
        // Foundry will now use the local artifact metadata
        // to display a friendly name in error messages.
        coordinator.fundSubscription(1, 2);
    }
}

This is failing as we haven't setup subscritpions and all the jazz but if you now run

forge test --mt testExample --fork-url $SEPOLIA_RPC_URL -vvvvv

You will indeed see the name

so basically Instead of interacting with an externally deployed instance, deploy the contract as part of your test on the forked chain. This way, the deployment is done using your local artifacts and Foundry can map the address back to the contract name.

But in this video Patrick can see the contract name in the terminal error section without any extra work, while I do the same thing and only see the address.

I haven't being pay so much details to this but I think @KMean made a solid point and Foundry has gone through many updates since Patrick filmed and release the course so maybe somethings changed but I digress in Patrick's voice The official Foundry course remains the source of truth.

[chainflash]

Yes maybe the problem is related to the update, is it the same for you or not?

[EngrPips]

I will check as soon as I can and circle back.
