Hardhat Deploy – ProviderError: Method EVM Snapshot Does Not Exist

hardhathardhat-deploy

I'm trying to run a test with hardhat, and have it deploy my deployments/fixtures with the command:

npx hardhat test --network rinkeby --deploy-fixture

When I run this, I get the following error:

ProviderError: The method evm_snapshot does not exist/is not available

I have a deploy folder containing all my methods to deploy, and npx hardhat deploy --network rinkeby works great.

What gives?

The fixture functionality currently doesn't work for testnets. If you want to run your tests on a testnet, you'll first have to deploy the contracts, and then run your tests.

A common "gotcha" of hardhat deploy. You have to use --network localhost when running a script with your own hardhat node locally.

The default network is the hardhat network otherwise.

Deploy WETH Contract – How to Deploy WETH Contract in Hardhat Test

You need to await the getContractFactory
.deployed() is, iirc, only in web3js (you can remove it here)
double check you contract name (« WETH », case sensitive) if it’s not solving it

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

describe("testing", function () {
  it("Should work", async function () {
    const Weth = await ethers.getContractFactory("WETH")
    const weth = await Weth.deploy()

    expect(await weth.symbol()).to.equal(“WETH”);
  });
 });
