Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Migrating from Jest to Vitest for your React Application
Native code coverage via v8 or istanbul.
-
Testing Vue components the right way
Writing tests is essential, and knowing whether you test all the required cases for your logic is even more critical. The most common testing coverage tool is Istanbul, where you can see how well your tests exercise your code by lines, functions, and branches. Below is an example of how the test coverage report looks in your terminal:
-
Don't target 100% coverage
Here is a quote from istanbul, one of the most used code coverage tool:
-
Unit testing like a Hacker
Unit testing framework was already implemented, using Vitest so I started hacking by setting up a coverage provider to explicitly identify the covered/uncovered lines and mentioned this to the maintainer in the comments. I used Istanbul 🇹🇷 for this purpose.

Auto-Publish Your Test Coverage Report on GitHub Pages
Your project probably has a coverage report. If you’re using Jest as your unit test runner, generating a coverage report is embedded in it. It is done with Istanbul under the hood, which generates a nice HTML page presenting the entire project unit test coverage.

Dear Linux, Privileged Ports Must Die
> This is a rant written by someone with just enough understanding to be dangerous, but not quite enough wisdom to know why things are still the way they are. Most of the complaints raised are subtly inaccurate.
Author seems aware of CAP_NET_BIND_SERVICE: https://source.small-tech.org/site.js/app/-/issues/169 and https://github.com/istanbuljs/nyc/issues/1281 – the "side effects" are NodeJS explicitly checking for it, so that's a NodeJS thing and not a Linux thing.
Yet curiously it's completely unmentioned in this article, in spite that this is probably what started the author's dislike of privileged ports. I guess it was inconvenient as it got in the way of angrily ranting.

Comprehensive coverage Jest+Playwright in Next.js TS
This approach will create two json coverage files, which will be merged together by NYC. Therefore the results will be purely local. If You don't mind using online tools like Codecov or Coveralls for merging data from different tests, then go ahead and use them. They will probably also be more accurate. But if You still want to learn how to get coverage from E2E, then please read through

When developing in React, what do you find most frustrating or cumbersome?
https://istanbul.js.org/ measures how much of your code is covered by tests
-
Production Ready React
Jest uses a package called Istanbul to provide test coverage metrics such as statement, branch, function, and line coverage so that you can understand and enforce the quality of your test suite, providing more confidence in releases.

Aggregating Unit Test Coverage for All Monorepo’s Packages
So let’s see if nyc (the code coverage generator) can help with that. Hmm… this documentation seems interesting! So basically what I understand from it is that I need to collect all the reports from the different packages and then run the nyc report over it. The flow should be like this:

Vitest In-Source Testing for SFC in Vue?
Next we’ll install Vitest and happy-dom to the project by running:
-
Migrating from Jest to Vitest for your React Application
JSDOM and happy-dom for DOM and browser API mocking
-
A question on testing a <select> element with Vitest / vue-test-utils
https://github.com/capricorn86/happy-dom/issues/618. Looks like some work was merged recently.
-
The Fetch API is finally coming to Node.js
I think you mean jsdom. You can try Happy DOM
-
vBulletin scraper ?
Well, I've actually done it using axios + happy-dom.

Testing your Solid.js code in vitest
You may have heard of vite, the slim fast dev server that scored an amazing as deserved 98% satisfaction on the state of js survey 2021. It's creators found unit testing too cumbersome and slow and decided to add their own perspective to the task. The result is vitest: it runs a vite server under the hood to transform the code to test as fast as possible, uses an enhanced flavor of chai to have jest-compatible assertions, integrates DOM mocking using jsdom or happy-dom and even the tiny-spy library that was just built as a separate library to allow for easy reuse is small and compatible with jest.
- Happy-DOM: a jsdom alternative that can server side render web components
-
Testing Solid.js code beyond jest
happy-dom, more lightweight
What are some alternatives?
jest - Delightful JavaScript Testing.
jsdom - A JavaScript implementation of various web standards, for use with Node.js
istanbul - Yet another JS code coverage tool that computes statement, line, function and branch coverage with module loader hooks to transparently add coverage when running tests. Supports all JS coverage use cases including unit tests, server side functional tests and browser tests. Built for scale.
vitest - Next generation testing framework powered by Vite.
Cucumber.js - Cucumber for JavaScript
linkedom - A triple-linked lists based DOM implementation.
playwright-test-coverage - Extends Playwright test to measure code coverage
vite - Next generation frontend tooling. It's fast!
mocha - ☕️ simple, flexible, fun javascript test framework for node.js & the browser
solid-primitives - A library of high-quality primitives that extend SolidJS reactivity.
jasmine - Simple JavaScript testing framework for browsers and node.js
snoop - Easy breezy test spies fo sheezy.
