It may be timing to switch from Jest to Vitest... 🤔

[ota-meshi]

I didn't know that Jest had such a problem:sweat: I think it's good to switch to Vitest if possible.

[ybiquitous]

@ota-meshi Have you some experience of Vitest? I don't know it so much, honestly 😅

[ota-meshi]

Sorry, I'm not familiar with Vitest 😅

Hey hey! Just want to mention that it would be really nice to make the vs code extension work with the v16 of stylelint, so we could upgrade its version in our codebase! Is there any rough ETA for when this PR could be finished?

[ybiquitous]

@kizu I have no time to tackle this PR, including dependency problems, for now. 😓

If you are interested, you could tackle this challenge.
