Warnings of test not wrapped in act since 9.3.2 about dom-testing-library

[MatanBobi]

We have an open PR to remove that: testing-library/testing-library-docs#1329
This was relevant back when peerDependencies weren't downloaded in case they weren't installed already.
You can safely remove @testing-library/dom from your devDependencies.
I'm resolving this one as it's a duplicate of the open issue in RTL (testing-library/react-testing-library#1216) and for the specific concern you've raised, we already have an open PR in the docs.
Thanks!

Uh oh! @joaopedrodcf, the image you shared is missing helpful alt text. Check your issue body.

Alt text is an invisible description that helps screen readers describe images to blind or low-vision users. If you are using markdown to display images, add your alt text inside the brackets of the markdown image.

Thank you so much 🙏

Hi @joaopedrodcf.
The act error is from React Testing Library, is there any specific reason why you have DTL installed explicitly?
We have this issue that suggests it might be related to multiple DTL versions installed: testing-library/react-testing-library#1216

Wow, that was really quick @MatanBobi :D

Yeah, it was getting duplicated like this! After removing it, it works again 🥇

I think I saw it in next documentation but tried to look again but can't find it anymore maybe they updated their docs 😆

Gonna close the issue

Actually found the reason @MatanBobi why I add installed the @testing-library/dom.

In the docs of user-event they say that we need to install it:
https://testing-library.com/docs/ecosystem-user-event/

Even yarn will say that a peer dep is not met if we don't install it

Just to add more information for the issue:

It can be seen in the yarn.lock the 9.0.0 was resolved to 9.3.1 and then 9.3.3 was the one I installed manually

So the solution for me was to basically relly in "resolutions" ( overrides in npm ) to force the same version and not having a warning in doing yarn because of a missing peer dependency

// package.json

{
    "devDependencies": {
        "@testing-library/dom": "9.3.3",
        "@testing-library/react": "14.0.0",
        "@testing-library/user-event": "14.5.1",
    },
    "resolutions": {
        "@testing-library/dom": "9.3.3"
    }
}
