Creating Test

[armontej]

I like how Patrick pushes us to try to create our own test in the course, but I have a hard time figureing where to start or how to even create my own test. For example when trying to create test for lesson 14 with the randomIpfNft.test.js. Can anyone point in the direction of some material that could help me better understand how to do this.

Hello @armontej

I totally understand your confusion cause i've been there before.

The official hardhat docs, is a very good recommendation if you are looking to start writing tests, do check it out here
https://hardhat.org/tutorial/testing-contracts

After doing that, like they say, the best way to learn to code is to write codes. Get a simple contract, like a storage contract that just stores and retrieve funds, and try to write tests to confirm that the variable is initially 0, and the storing and retrieving works.

From there, advance to a more harder contract, and you'd pick up testing in no time🙂

Thank you m8

@Darlington02 i am trying to start the testing and when i copy and paste the code in like it says:

describe("Token contract", function () {
  it("Deployment should assign the total supply of tokens to the owner", async function () {
    const [owner] = await ethers.getSigners();

    const Token = await ethers.getContractFactory("Token");

    const hardhatToken = await Token.deploy();

    const ownerBalance = await hardhatToken.balanceOf(owner.address);
    expect(await hardhatToken.totalSupply()).to.equal(ownerBalance);
  });
});

i get the out come

the website says i should get

$ npx hardhat test

Token contract
✓ Deployment should assign the total supply of tokens to the owner (654ms)

1 passing (663ms)

is it not an issue that i don't get the exact same outcome before i continue

[Darlington02]

Did you create the token contract before writing the tests? If no, then hardhat cant find what to test.

Go back a page or two page before in the docs i sent you, and copy and compile the contract for the token first.

[armontej]

yeah i added the Token.sol file into the hardhat-test directory that i made
i copied and pasted the code that was in the create contract

[armontej]

figured it out thank you!
