Jest. The matchers cover basically all the same use cases. Not to mention that jest's "expect.arrayContaining" and "expect.objectContaining" literally blow most other assertion libraries out of the water.

  I don't know what kind of shop you're running where JS libraries are 'literally' getting blown out of water but I like it.

    It would not surprise me if there's javascript running on nuclear subs. It's already made it to space: https://www.infoq.com/news/2020/06/javascript-spacex-dragon/ https://www.infoq.com/news/2020/06/javascript-spacex-dragon/

      In the trivial sense, sure, someone probably has a web browser on a nuclear sub. But if you're talking software written for the operation of the sub itself, I expect it's either Ada, C89 or C++. Ada was, after all, developed specifically by the DoD for exactly such purposes.

  Jest as a test runner is very slow. I normally run mocha while importing the expects from jest.

I really enjoy Ava [1] or anything assert-tape-like [2]. "uvu" [3] is getting a lot of love lately, but it's very feature limited and much of it's touted advantages are at the detriment to feature set.

const { deepStrictEqual: same } = require('assert');

I like simplicity of mochajs but chai felt really outdated. Jest on the other hand is so complicated and magical that I have no confidence in tests that I write using it. That's why I've created earljs: https://earljs.dev/ https://earljs.dev/ It's a modern, fully typesafe chai replacement that works great with mocha. Very inspired by Jest (matchers, snapshots) but without magic that makes Jest hard to reason about.
