I want to resurrect @MariaAga’s effort to upgrade our frameworks.

Thanks @Shimon_Shtein !

I do know that there is a problem with our snapshot tests, so as a first step I would encourage all plugin maintainers to stop relying on those tests and either remove them completely, or change them to a different approach.

I saw this comment the other day in Support for React 18 · Issue #2524 · enzymejs/enzyme · GitHub

If you’ve got a large number of enzyme unit tests (> 1200 in our case) but you still want to switch to react 18 right now and migrate to react-testing-library progressively you can do it with this method (inspired by this article)

@Shimon_Shtein

react to v17

For React 17 there’s an unofficial adapter for Enzyme: GitHub - wojtekmaj/enzyme-adapter-react-17: Unofficial adapter for React 17 for Enzyme.

but for React 18 it will definitely break… but with Support for React 18 · Issue #2524 · enzymejs/enzyme · GitHub we might not need to replace all of our tests that used Enzyme.
