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

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

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).

Unit Testing in Node.js and TypeScript: A Comprehensive Guide with Jest Integration
If you are using a mocking library, such as sinon, jest-mock, or ts-mockito, make sure that it is compatible with Jest. You may need to install additional packages or configure them in your configuration file. For example, to use sinon with Jest, you can install the sinon-jest package and add the following to your configuration file:
-
Express API Testing
Mocha is a test runner, Chai is an assertion library, Sinon is a mocking library, this normally the combination you would need to use if you choose mocha, but there are others.
-
Alternative to AWS Mock
Instead, use pure functions + dependency inject your stubs (e.g. parameter to function). Also note, no need for Sinon or some other test double library. JavaScript is so good nowadays to easily make objects/classes/functions or any combination thereof on the fly that are terse.

Unit testing: What to use, and how?
I've had some good experiences with Ava + Sinon. I've personally disliked Jest because it seemed to do some weird trickery in the background that prevented me from using ES modules.

Can AI help me write tests on legacy code?
🤖 You can use the Mocha testing framework with the Chai assertion library to write tests for your Express controller. You can also use the Sinon library to mock the database calls. This will allow you to test the controller without actually making a call to the database. You can also use the SuperTest library to make HTTP requests to the controller and test the response.

You can use sinon js to create a mock version of your http library (axios) that responds with the data you’re expecting.

Unit testing with React and Cypress
Assertions are the checkpoints of our test block that confirm if an automated test has passed or failed. Cypress bundles the Chai, jQuery, and Sinon.JS libraries for assertions. They check the desired, expected application in which the test is running. A complete listing of assertions can be found in the documentation here.

When to use DI?
ES module is basically a "class" that you inject dependencies into through imports. And for tests you just use something like sinon to swap module dependencies for mocks.

How to test a function that uses moment to format a date ? usimg karma
You can use a tool like sinon to pass in your own function instead of the real moment library. From there you can write tests that ensure moment was invoked appropriately.
