Node v20.4.0 (Current)

Rafael Gonzaga

The new feature allows developers to write more reliable and predictable tests for time-dependent functionality. It includes MockTimers with the ability to mock setTimeout, setInterval from globals, node:timers, and node:timers/promises.

The feature provides a simple API to advance time, enable specific timers, and release all timers.

import assert from 'node:assert';
import { test } from 'node:test';

test('mocks setTimeout to be executed synchronously without having to actually wait for it', context => {
  const fn = context.mock.fn();
  // Optionally choose what to mock
  context.mock.timers.enable(['setTimeout']);
  const nineSecs = 9000;
  setTimeout(fn, nineSecs);

  const threeSeconds = 3000;
  context.mock.timers.tick(threeSeconds);
  context.mock.timers.tick(threeSeconds);
  context.mock.timers.tick(threeSeconds);

  assert.strictEqual(fn.mock.callCount(), 1);
});

Support to the explicit resource management proposal

Node is adding support to the explicit resource management proposal to its resources allowing users of TypeScript/babel to use using/await using with V8 support for everyone else on the way.

This feature was contributed by Moshe Atlow and Benjamin Gruenbaum in #48518.
