Testing Library

Libraries, utilities, and tools to enable you to write tests that resemble the way your software is used. @ReactJS, @VueJS, @Cypress_IO, @angular, @fbjest, more

[Corbin Crutchley @crutchcorn]

Heads up to anyone using JSDom for testing, I believe as of three days ago there was a change to some sub-deps that broke behavior for anyone upgrading their package lock:

I'm working on a fix right now

Welcome to the family!

I'm thrilled to finally announce the release of a new @testing-library, React RenderStream testing library.

We have been using the underlying approach in over 500 Apollo Client tests for a year now, and it has given us a new level of confidence.

Heads up @TestingLib users 🐙

Due to multiple issues we've observed in the past releases, we've just released a new major of React Testing Library (16) that moves @testing-library/dom to a peer dependency.
Keep in mind that you'll need to manually install DTL from that version.

[Kent C. Dodds 🐨 @kentcdodds]

It's official. @TestingLib is now THE testing solution for @reactjs. What a journey!

🚀 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

[Matan Borenkraout 🥬 @matanbobi]

🎉 🎉🎉
A new major version of React @TestingLib 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.

Here's an opportunity to contribute to @TestingLib'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_dev, just edit your setup file 🦉

[Matan Borenkraout 🥬 @matanbobi]

🚨 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 @TestingLib waitFor with a meaningful assertion.
