TEVM

We love TEVM. Full first-class tevm support — forks, fixtures, broader deploy targets — is on the roadmap.

Today you can already run your generated deployers against an in-memory TEVM via @deployoor/testing. No Hardhat network, no anvil, no disk writes — tests run like plain TypeScript scripts.

What's coming

• Forked mainnet state and snapshot fixtures as supported deploy/test targets
• Deeper tevm integration beyond the in-memory path @deployoor/testing proves today

What works now

pnpm add -D @deployoor/testing vitest

import { test, expect } from "vitest";
import { createTestClients } from "@deployoor/testing";
import { getOrDeployCounter } from "../deployers";
 
test("increment", async () => {
  const clients = await createTestClients();
  const { contract: counter } = await getOrDeployCounter({ ...clients, args: [0n] });
 
  await counter.write.increment();
  expect(await counter.read.number()).toBe(1n);
});

createTestClients() spins up a TEVM-backed in-memory chain and passes it to your deployers — the same getOrDeploy functions you use in deploy scripts.
