Painless CLI integration testing
We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I donât want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Speeding up the JavaScript ecosystem â The barrel file debacle
> In the popular jest test runner, each test file is executed in its own child process.
Is that confirmed?
I've been following this issue:
https://github.com/jestjs/jest/issues/6957
And what Jest actually does is still kind of muddy.
In contrast to that, other test runners like AVA have a clear description what happens when:

What Tools Are You Using to Test Your Code?
I've been looking at using japa or ava for web server testing but was curious what others were using and why.

[2023-07-14] Razuberi Development Update
Continued work on the test suite. Implementing AVA, with snapshotting. Making a lot of effort to have the snapshot directory structure match the test262 test directory structure by generating AVA test files.

Ask HN: What's your favorite software testing framework and why?
You might want to give ava a spin:
https://github.com/avajs/ava/
It has a TAP reporter, but more importantly, as opposed to the more popular solutions, like Jest, the way it achieves parallelism is explained in the docs and won't change anytime soon, thus preventing wonky, hard to debug errors which occur when this part is abstracted away.

The new React's documentation
I switched to ava for that reason and have been very happy with it. But vitest looks nice, too. Thanks for the pointer.

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

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.
-
Tech stack discussion
Ava for a simpler environment than Jest, which I usually use. I need to check how to mock ESM with it, though.

The best testing strategies for frontends
With the advent of tools like Puppeteer and now Playwright, end-to-end testing has become much easier and more reliable. For anyone who's used Selenium in the past, you know what I'm talking about. Puppeteer has opened the way in terms of E2E tooling, but Playwright has taken it to the next level and made it easier to await for certain selectors or conditions to be fulfilled (via locators), thus making tests more reliable and less flaky. Also, it's a game changer that it introduced a test-runner - this made the integration between the headless browser and the actual test code much smoother.

HTML to PDF renderers: A simple comparison
HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

Let's build a screenshot API
Playwright seems to be a superior library for working with headless browsers than Puppeteer, but I will go with Puppeteer.

How to build a WhatsApp AI assistant
This library works by creating an instance of WhatsApp web running inside an instance of headless chrome automated by puppeteer. In my testing, I ran into tons of compatibility issues when trying to use these dependencies inside anything other than a bare-bones Node.js + express server. Also, we canât spin up a new instance of chrome and WhatsApp web each time a user sends a message, this will exhaust our allowed WhatsApp connections (4 max), not to mention that doing this will make the response times painfully slow.
