Solidity – Writing Foundry Tests for Functions with Arrays of Structs

foundrysoliditytesting

I have this foundry function and I don't have any idea how to pass an array of structs to batchList function

function test_ListMockERC721() public {
    vm.prank(add1);
    erc721Mock.mint(msg.sender);
    marketsc.batchList([[erc721Mock, 1, 0, add1, 1], [erc721Mock, 2, 0, add1, 1]]);
}

This is the function signature from the smart contract:

function batchList(InputOrder[] calldata inputOrders) external;

Best Answer

I assume that InputOrder is a structure. Then the solution is:

function test_ListMockERC721() public {
    vm.prank(add1);
    erc721Mock.mint(msg.sender);
    marketsc.InputOrder[] memory inputOtders = new marketsc.InputOrder[](2);
    inputOtders[0] = marketsc.InputOrder(erc721Mock, 1, 0, add1, 1);
    inputOtders[1] = marketsc.InputOrder(erc721Mock, 2, 0, add1, 1);
    marketsc.batchList(inputOtders);
}

Problem is you are trying to pass javascript array coords to a solidity function loopCoords. Solidity function is not able to interpret coords as an array and it is interpreting it as a mapping.

I am not sure but I think your problem is how to pass an array as a parameter from javascript web3 to a solidity function You need to pass an argument of loopCoords as the following:

await coordsContract.loopCoords.getData(coords)

When you want to withdraw and the signing account is the deployer and test contract itself (it's the same), like you have, then you need to give the contract TestContract is Test the ability to receive ether, like you would do for any other contract. Add the following to the contracts body.

// Function to receive Ether. msg.data must be empty
receive() external payable {}

// Fallback function is called when msg.data is not empty
fallback() external payable {}

Other than that you could use vm.prank and specify an EOA which is capable of receiving ether anyway. Remember you would need to use vm.prank for contract deployment (owner is not test contract but EOA and before withdraw function execution)
