Testing Library provides a great set of accessibility-focused tools to locating elements when writing tests. It was created by Kent C Dodds, one of my longtime favorite educators on front-end and testing topics. Since the initial release in 2018 as "React Testing Library", it's grown in popularity beyond its React component testing roots. It now has plugins for all major test runners and JavaScript frameworks, and in 2022 some of its patterns were adopted in Playwright's test runner as the recommended way to locate elements.

Probably Enzyme was the first to popularize component testing in React by doing shallow rendering and expecting some things to be there in the React component tree. Then React Testing library came and took component testing to a whole new level.

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.

I'm writing an intergration test with Testing Library where I'm on a boards dashboard area and a user can click a button to create an item on the board. I'm using an intercepting route to do show the popup form. Once finished the user goes back to their area and should see the created board.

This article uses Jest and React Testing Library. It's okay if you want to use other libraries, the fundamentals in this article will help you there as well.

This is the idea behind Testing-Library from what I understand.

The Testing Library: The Testing Library offers guidance on best practices for testing user interfaces effectively, with a focus on user-centric testing.

There are great tools like Testing Library that render a single component in a single state and then programmatically inspect the resulting DOM. However, the salient details of the rendered HTML – like color, layout, and scale – are hard to express. So, the tests end up brittle (over-specified) or insufficient (under-specified).

We are continuing to add new project templates for various types of projects, and we've recently created one for the infamous combination of React with Vite tooling.

Go to https://react.dev/?uwu=true for a surprise.

You can use any frontend framework you want — react-based tooling, however, has a natural advantage as it models everything as a function of state, which can map 1:1 with the concept in Burr. In the demo app we use react, react-query, and tailwind, but we’ll be skipping over this largely (it is not central to the purpose of the post).

Oddly, no info on changelog: https://github.com/facebook/react/blob/main/CHANGELOG.md

In this post, we get to know more about Preact, one of this year's trending libraries. And we'll compare it to React to see which one suits better for our projects.

Google Translate and many other libraries break React based sites if they are using refs.

I don't think that point it falls under "written on naive assumptions"

This isn’t an accident; when Meta introduced React Server Components, Dan Abramov explicitly stated that they collaborated with the Next.js team to develop the RSC webpack plugin.
