I am not sure where I am going wrong, but I think it is within my const [owner, _] = ... area. I could be wrong, but I am not sure where, if anywhere I should be putting another argument, or inserting the abi string somewhere.

My test.js file:

const {ethers} = require("hardhat");
const {expect} = require("chai");

describe("BCCasino tests", () => {
    let token20, token721, token1155, casino;
    
    beforeEach(async () => {
        
        const Token20 = await ethers.getContractFactory();
        const Token721 = await ethers.getContractFactory();
        const Token1155 = await ethers.getContractFactory();

        const ContractFactory = await ethers.getContractFactory("BCCasino");

        token20 = await Token20.deploy();
        token721 = await Token721.deploy();
        token1155 = await Token1155.deploy();

        await token20.deployed();
        await token721.deployed();  
        await token1155.deployed();

        casino = await CasinoFactory.deploy(
            token20.address, 
            token721.address,
            token1155.address
        );

        await casino.deployed();
    
    });

    it("..should deploy correctly", async () => {
        //const parsedABI = JSON.parse("BCCasino");
        const [owner, _]= await ethers.getSigners();

        expect(await casino.owner()).to.equal(owner.address);
        expect(await casino.token20()).to.equal(token20.address);
        expect(await casino.token721()).to.equal(token721.address);
        expect(await casino.token1155()).to.equal(token1155.address);

        
    });
});

here is the .sol file:

        address user = msg.sender;
        uint256 amount = machineToAmount[machineId];
        token20.transferFrom(user, address(this), amount);
        deposits[user][machineId] += amount;
        emit Deposit(user, machineId, amount);
        return true;
    }

    function reward(address user, 
                    uint256 amount,

        require(rewardType < 3, "Invalid reward Type");
        require(
            deposits[user][machineId] >= machineToAmount[machineId],
            "User didn't make a deposit for the game. Invalid request"
        );

        deposits[user][machineId] -= machineToAmount[machineId];

        if(rewardType == 2) {
            token721.mint(user);
            emit Reward(user, 2, 1);
         } else if (rewardType == 1){
            token1155.mint(user, 1);
            emit Reward(user, 1, 1);
         } else {
            token20.mint(user, amount);
            emit Reward(user, 0, amount);
         }

         return true;
        }

    function totalMachine() external view returns(uint256) {
        return machineIdCounter.current();
    }
    }

Below is the error I'm getting:

 BCCasino tests

     TypeError: abi is not iterable
      at addGasToAbiMethodsIfNecessary (node_modules\@nomiclabs\hardhat-ethers\src\internal\helpers.ts:409:28)

      at Context.<anonymous> (test\BCCasino.test.js:9:25)

Any help is much appreciated.

I fixed my code and inserted the string ABIs in the deploy statements, as suggested but now I get this error when I try to test.

  1) BCCasino tests

here is updated test.js file.

const {ethers} = require("hardhat");

        const Token1155 = await ethers.getContractFactory("BC1155");
        const CasinoFactory = await ethers.getContractFactory("BCCasino");

        token721 = await Token721.deploy();
        token1155 = await Token1155.deploy();

        await token20.deployed();
        await token721.deployed();  
        await token1155.deployed();

        casino = await CasinoFactory.deploy(
            token20.address, 
            token721.address,
            token1155.address
        );

        await casino.deployed();
    
    });

    it("..should deploy correctly", async () => {
        //const parsedABI = JSON.parse("BCCasino");
        const [owner, _]= await ethers.getSigners();

        expect(await casino.owner()).to.equal(owner.address);

        expect(await casino.token721()).to.equal(token721.address);
        expect(await casino.token1155()).to.equal(token1155.address);

        
    });
});

you are not passing the contract name to the getContractFactory thats why you have the error, you just have to provide the name of the contract you want to deploy with that factory.

here is your updated test.js file

const Token20 = await ethers.getContractFactory("BCToken");
const Token721 = await ethers.getContractFactory("BCNFT");
const Token1155 = await ethers.getContractFactory("BC1155");
const CasinoFactory = await ethers.getContractFactory("BCCasino");

  • Thank you. I did that and now I am getting the following error message........... "before each" hook for "..should deploy correctly": Error: missing argument: in Contract constructor (count=0, expectedCount=1, code=MISSING_ARGUMENT, version=contracts/5.7.0) Jun 2 at 14:56

for the error, Error: missing argument: in Contract constructor (count=0, expectedCount=1, code=MISSING_ARGUMENT, version=contracts/5.7.0) you need to pass in a constructor in the test cos there is a constructor in you .sol code
