Hardhat: how to deploy contract with an interface in constructor?

Question

I have a contract called Token.sol

Inside there is an interface:

interface TokenInterface {
}

followed by the contract with constructor having that interface

contract Token {

  TokenInterface public tokenInterface;

  constructor(TokenInterface _tokenInterface) {
    tokenInterface = _tokenInterface;
  }

How do I deploy this in hardhat test? Right now I have

    Token = await ethers.getContractFactory("Token");
    [owner, addr1, addr2, ...addrs] = await ethers.getSigners();

    token = await Token.deploy();

Answer 1

try this:

const Test = await hre.ethers.getContractFactory("TestInterface");
const test = await Test.deploy();

const Token = await hre.ethers.getContractFactory("Token");
const token = await Token.deploy(test.address);

once you deploy the constract that implements the interface you can get the address and pass it as a parameter to the deploy function as you can see in the example
