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. (Link in next Post)

📣 @testing-library/react@13.1.0 just shipped with a new built-in renderHook function that operates similar to @testing-library/react-hooks but with support for React v18 🎉

Happy New Year from me to you (through your tests 😉).
My footer auto-updated to 2022 and my failing unit test is wishing me a Happy New Year 🎉

This is in response to the question: "Where did you learn accessibility?" We LOVE this side-effect of people using @TestingLib <3 #a11y

Cypress Testing Library v7.0.0-beta.2 was just published and we'd like your help testing it (especially if you use TypeScript): github.com/testing-library/c… We moved types from DefinitelyTyped to the repo and removed deprecated queries (only find* queries is supported). Try it!

PSA
If you're still using #enzyme over @TestingLib for your @reactjs codebase then you're going to have a massive headache migrating to functional components. 1/n

That's probably a bug and we should simulate submitting the form on enter (if the element being typed into is an input within a form). PRs welcome :)

Awesome! Even better than the mutation observer shim is to use the latest version of jsdom with either the latest version of jest or jest-environment-jsdom-sixteen.

And I make doing that for UI much easier 😘
I write tests following TDD when it makes sense

Download numbers show me a bit behind enzyme but catching up fast. Enzyme's download numbers are still growing, but the growth is slowing and my growth is accelerating.

Also, whatwg-fetch is not intended to actually support Node. It only really works because of jsdom.
