screen doesn't have container key

[Belco90]

Hi Pavel, thanks for opening this issue. Damn, we tried to fix something doesn’t even exist. I’ll take care of this one tomorrow morning.

[gndelia]

Reviewing the original issue, the problem seems to be that container is not exposed in screen - it only exposes the bound queries + debug.

In that case then we should allow the render result to use the container, as there's no other way to access it.

[Belco90]

Yep, I just assumed container was available under screen but it isn’t. Better to double check the docs next time.

Should be easy just to revert that fix.

[gndelia]

I will create a PR just reverting that one

[gndelia]

created!

[timdeschryver]

that makes sense 🤦‍♂️😅

Not sure if you should allow render to use container tho. https://kentcdodds.com/blog/common-mistakes-with-react-testing-library#using-container-to-query-for-elements

[Belco90]

@timdeschryver I think we need its own no-container rule or however it will be called, but something outside prefer-screen-queries.
