As style sheets became the responsibility of larger and larger teams, CSS’ global scope and specificity were often at odds with team dynamics. Style collisions became increasingly common, where changes introduced by one developer would inadvertently affect styles elsewhere on the website. As the old joke goes: two CSS properties walk into a bar; a bar stool in a completely different bar falls over. As these issues and the number of people experiencing them multiplied, so too did new CSS methodologies, particularly those focused on style sheet architectures. Before long, we had SMACSS, SUIT CSS, BEM, ITCSS, and more. Third party supersets of CSS also appeared during this time, such as Sass and LESS, which gave style sheet authors access to scripting features like variables and loops.

CSS (Cascading Style Sheets) are rules to describe how your HTML elements look. Writing good CSS is hard. It usually takes many years of experience and frustration of shooting yourself in the foot before one is able to write maintainable and scalable CSS. CSS, having a global namespace, is fundamentally designed for web documents, and not really for web apps that favor a components architecture. Hence, experienced front end developers have designed methodologies to guide people on how to write organized CSS for complex projects, such as using SMACSS, BEM, SUIT CSS, etc.

This is actually super bad practice. I really dislike scoped css.

When I see devs using scoped css the class names always end up like `.box` or `.name`.

Having to think about classnames and writing Sass makes me much more aware of the structure of the components I'm styling. Frankly I think only JS oriented devs like scoped CSS and frontend who love html/css and the challenges of architecturing good CSS don't egt any benefit out of styled components (since you're using atomic css like Tailwind and/or BEM-style which always "scopes" classnames with the component name.

In general any solid guidelines makes CSS instantly 10x better and that's all most projects needs, and it's often what most projects lack.

SuitCSS works great with Vue in my experience, and can even be linted with postcss-bem-linter :

SUITCSS

Tachyons developer, Adam Morse in this talk at DevShop London 2016, talks about motivation behind Tachyons. He discusses the problem of continuous over-riding your own written CSS code, writing tons of CSS code, struggle to keep all this info in your head and the need to refactor 200Kb CSS file. His answer to the problem is Tachyons. SUIT CSS (Style Tools for UI Components). was the initial inspiration that lead to creation of Tachyons. Unlike Bootstrap where you redefine a component multiple times, SUIT had a class which would not redefine itself or mutate later.

This component syntax is mainly taken from Suit CSS with minor modifications.

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 don’t 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!

> 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:

I've been looking at using japa or ava for web server testing but was curious what others were using and why.

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.

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.

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

Runs unit tests using AVA.

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

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.

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