A Hardhat Plugin To Test Huff Contracts

npm install huff-deployer --save-dev

You need to have the Huff compiler (Rust version) installed in your machine. To install the compiler go to: https://github.com/huff-language/huff-rs

Add the following to your hardhat.config.js file:

require("huff-deployer");

If you are using TypeScript, add the following to your hardhat.config.ts file:

import "huff-deployer";

Then on your test file, import huffDeployer and deploy your Huff contract:

import { expect } from "chai";
import { ethers } from "hardhat";

import { huffDeployer } from "hardhat";

describe("Owned", () => {
  it("should change the owner", async () => {
    const [owner, newOwner] = await ethers.getSigners();

    const owned = await huffDeployer.deploy("Owned", false,
    [owner.address]); // <--- Deploy the contract
    expect(await owned.owner()).to.equal(owner.address);

    await owned.setOwner(newOwner.address);
    expect(await owned.owner()).to.equal(newOwner.address);
  });
});

huffDeployer.deploy accepts 3 arguments:

1. targetContract: The name of the Huff contract.
2. generateSolidityInterface (optional): Optionally generates a Solidity interface.
3. constructorArgs (optional): The constructor arguments.
4. signer (optional): It will default to Hardhat's signer 0.
