Good gravy! Node has a test framework, Now what does that actually mean?

You download Jest and test right? well what if you could just

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

test('a description', () => {
  assert.strictEqual(1, 1);
});

output:

(node:27143) ExperimentalWarning: The test runner is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)

Agh, a reporter only a mother could love!

Sidenote

Thats exactly how Rust handles its tests, there is no framework and usually all tests in the same file as the source which is actually really nice.

What does it mean?

Node.js is shooting for you to forget Jest, will you? maybe one day, now? no!

But it's a step in the right direction standardising testing is a very good idea.
