I want to set up a Foundry test where I create a UniswapV3Factory and deploy a pool with two tokens. Here is what I have so far:

// SPDX-License-Identifier: UNLICENSED
pragma solidity =0.7.6;

import '../src/libraries/BitMath.sol';
import {TestERC20} from './TestERC20.sol';
import "forge-std/console.sol";
import "../src/UniswapV3Factory.sol";
import "../src/UniswapV3Pool.sol";
import '../src/interfaces/IUniswapV3Pool.sol';
import '../lib/openzeppelin-contracts/contracts/token/ERC20/IERC20.sol';
import '../lib/openzeppelin-contracts/contracts/token/ERC20/ERC20.sol';

contract UniswapV3Test {
    address internal user1;

    IERC20 token0;
    IERC20 token1;

    function setUp() public {
        user1 = address(1);

        token0 = new ERC20("Token1", "T1");
        token1 = new ERC20("Token2", "T2");
    }

    function testDeployPool() external {
        UniswapV3Factory factory = new UniswapV3Factory();
        IUniswapV3Pool pool = IUniswapV3Pool(factory.createPool(address(token0), address(token1), 0));
        console.log('tick spacing', pool.tickSpacing());
    }

}

When I run forge test -vvvv a revert happens on UniswapV3Factory::createPool

Anybody know why?
