🚀 We released #Angular Testing Library v16 today

With this update, you receive the latest specification updates for role/element mappings to align with WAI-ARIA 1.2.

Why should you care?
🔎 better role support, including new roles
⚠️ existing queries might behave differently

🎉 🎉🎉
A new major version of React Testing Library was released (15.0.0) - This release drops support for Node 14, Node 16 and most importantly, adds support for new ARIA roles defined as part of WAI-ARIA 1.2.
If you have any feedback or issues, feel free to reach out.

We're really happy to officially have the Solid Testing Library as part of our ecosystem now. Many thanks to Daniel Afonso for pushing it!

Here's an opportunity to contribute to Testing Library's jest-dom 🦉 and dive into the world of accessibility: Create the toBeActiveDescendant custom matcher. Your chance to learn and make a positive impact awaits.

We see this asked quite a lot: If you've migrated from Jest to Vitest and looking for the jest-dom equivalent for Vitest, just edit your setup file 🦉

🚨 Implementation detail 🚨

Lately, I've been seeing this pattern for testing async stuff. This pattern creates a new promise and awaits for it to resolve.
This means we'll wait for all async operations to finish.
Prefer Testing Library waitFor with a meaningful assertion.

Happy New Year from me to you (through your tests 😉).

So eslint-plugin-testing-library v5 has been just released! Including support for ESLint v8. Make sure you check the breaking changes before upgrading: github.com/testing-librar…

Huge thanks to Michaël De Boey who really pushed things forward to get this new version published.

React and react component testing have come a long way. I so agree with this article. Lets not use enzyme.js anymore 👋

jest-dom v5.14.0 introduces two new matchers:

- toHaveAccessibleName
- toHaveAccessibleDescription

Another step towards promoting the use of more semantic and accessible markup. Making sure you properly label and describe elements has never been easier.

Starting with v5.13.0 jest-dom has a new matcher toHaveErrorMessage. This is a big step in promoting the use of more semantic and accessible markup to flag errors in form elements.
