Express API Testing
Last but not least important are ava, uvu and tape; they are a really light and fast test runners.

Test Svelte Component Using Vitest & Playwright
Vitest: A Vite-native unit test framework. (alternative: Jest, uvu)

SvelteKit uvu Testing: Fast Component Unit Tests
Most important here is not to forget to include test.run() at the end… I’ve done that a few times 😅. Notice how we are able to use aliases in lines 1–3. You can see the full range of assert methods available in the uvu docs.

Creating a Chai like assertion library using proxies
For the past few weeks I’ve taken the (arguably pointless) work of migrating Felte from using Jest to uvu. This is a really tedious work by itself, but one of details that would have made this work even more tedious is that Jest prefers assertions to the style of expect(…).toBe* while uvu gives you freedom to choose any assertion library, although there’s an official uvu/assert module that comes with assertions to the style of assert.is(value, expected).

Test Coverage in Svelte
Hello everyone, I'm using uvu for testing. And installed c8 for coverage. Yet it doesn't seem to be able to pick up test .svelte files. Does anyone knows how to achieve this or any other way of getting .svelte files coverage? Thanks

Don't be a dolt like me: Set Up Debugging in VSCode!
Yes! There’s even an example test written for the svelte counter demo in the repo’s examples!

Chaijs.com just let their domain expire
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.

Jest is great for front-end (or full stack integration) testing, but I feel it's specialized for that use-case and doesn't always play nice with backend/middle-tier testing needs.

Why Jest is not for me
For Node, I lean towards UVU by @lukeed due to its simplicity. Its lightweight, fast, supports ESM out of the box. It feels like an easier to setup modern Mocha (without the wide array of plugins).
What are some alternatives?
jest - Delightful JavaScript Testing.
mocha - ☕️ simple, flexible, fun javascript test framework for node.js & the browser
svelte-starter-kit - Svelte with brilliant bells and useful whistles
tap - Test Anything Protocol tools for node
ava - Node.js test runner that lets you develop with confidence 🚀
tape - tap-producing test harness for node and browsers
Sinon.JS - Test spies, stubs and mocks for JavaScript.
WebdriverIO - Next-gen browser and mobile automation test framework for Node.js
supertest - 🕷 Super-agent driven library for testing node.js HTTP servers using a fluent API. Maintained for @forwardemail, @ladjs, @spamscanner, @breejs, @cabinjs, and @lassjs.
