Open-Source Web3 Ethereum Projects at Hella Labs

Open Source Web3 Ethereum Projects

Hella Labs supports several Ethereum open-source projects. These projects specialize in test automation.

Projects:

Foundry Anvil Testcontainers Nodejs

This repository provides a Testcontainers module for Node.js to run a customized Anvil node in your E2E tests.

This Typescript module provides a Fluent API style method of configuring and starting the Anvil node. And during your test execution, the module provides a viem test client and streamlined helper methods to interact with the node.

Get started with Foundry Anvil Testcontainers Nodejs by following the steps below.

Install:

pnpm add -D @hellaweb3/foundryanvil-testcontainers-nodejs

Setup:

describe("AnvilContainer", () => {
  let container: StartedAnvilContainer;

  beforeAll(async () => {
    const options = new AnvilOptions()
      .logs.verboseLogs(LogVerbosity.Five)
      .logs.jsonLogFormat()
      .account.withRandomMnemonic()
      .evm.autoImpersonate();

    container = await new AnvilContainer(options).start();
  }, 60000);

  afterAll(async () => {
    if (container) await container.stop();
  });
});

Wiremock Testcontainers Nodejs

wiremock-testcontainers-nodejs is a Typescript nodejs library that spins up a WireMock instance with Testcontainers. It provides a fluent API to configure and start WireMock containers, including support for loading mappings and files from recorded Wiremock sessions.

Get started with Wiremock Testcontainers Nodejs by following the steps below.

Install:

pnpm add -D @hellaweb3/wiremock-testcontainers-nodejs testcontainers

Setup:

import { WiremockContainer } from "@hellaweb3/wiremock-testcontainers-nodejs";

describe("E2E Test", () => {
  let container;

  beforeAll(async () => {
    container = await new WiremockContainer()
      .withMappings("./test/__mocks__/wiremock")
      .start();
  }, 60000);

  afterAll(async () => {
    await container.stop();
  });

  it("should interact with WireMock", async () => {
    const url = container.rpcUrl;
    // Your test logic here
  });
});
