How to forge test an Array in SOLIDITY?

i wrote this code but i am confuse how to make a test script for it. because how do i input an array into the parameter? when i try to run the test script it says undeclared identifier names, uris, description

smart contract code:

function batchMintUniqueNFT(
        string[] memory _names,
        string[] memory _descriptions,
        string[] memory _images
    ) external onlyOwner{
        if(_names.length != _descriptions.length  
            _descriptions.length != _images.length 
            _images.length != _names.length
        ){
            revert UnbalancedMetadataLength(_names.length, _descriptions.length, _images.length);
        }

        uint256 amount = _names.length;
        if(amount == 0){
            revert InsuficientAmount(amount);
        }

        uint256 startTokenID = _nextTokenId();
        _mint(msg.sender, amount);
        for(uint256 i = 0; i < amount; i++){
            uint256 tokenID = startTokenID + i;
            string memory metadata = GenerateMetadata(_names[i], _descriptions[i], _images[i]);
            tokenURIs[tokenID] = metadata;

            emit MintingSuccess(msg.sender, tokenID, metadata);
        }
        successMinted += amount;
    }

i tried to test with this it fail:

function testbatchmintunique() external {
        string ;
        string ;
        string ;

        names[0] = "keren 1"; descriptions[0] = "deskripsi 1"; uris[0] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[1] = "keren 2"; descriptions[1] = "deskripsi 2"; uris[1] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[2] = "keren 3"; descriptions[2] = "deskripsi 3"; uris[2] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[3] = "keren 4"; descriptions[3] = "deskripsi 4"; uris[3] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[4] = "keren 5"; descriptions[4] = "deskripsi 5"; uris[4] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[5] = "keren 6"; descriptions[5] = "deskripsi 6"; uris[5] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[6] = "keren 7"; descriptions[6] = "deskripsi 7"; uris[6] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[7] = "keren 8"; descriptions[7] = "deskripsi 8"; uris[7] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[8] = "keren 9"; descriptions[8] = "deskripsi 9"; uris[8] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";
        names[9] = "keren 10"; descriptions[9] = "deskripsi 10"; uris[9] = "https://ipfs.io/ipfs/bafkreihqaswfkli5plhmicnmqq6zqgci32tk26jxk7lix42ktkowc62cha";

        ketewelnft.batchMintUniqueNFT(names, descriptions, uris);
    }

I think you simply forgot the declaration in the beginning of the test:

function testbatchmintunique() external {
    string[10] memory names;
    string[10] memory descriptions;
    string[10] memory uris;

    ...
}
