Support Jest 28 with `@vue/cli-plugin-unit-jest`

[sceee]

What problem does this feature solve?

Since Jest 18 was released ( https://jestjs.io/blog/2022/04/25/jest-28 ), it would be preferable if @vue/cli-plugin-unit-jest also supports it.

There is also already a version 28 for ts-jest available that is compatible with Jest 28.

What does the proposed API look like?

Support Jest 18 with @vue/cli-plugin-unit-jest

I think you mean jest 28 instead of 18 😉

And @vue/vue3-jest is now at 28.0.0 too.

It'd be nice if you add support for jest v28. Waiting for it :)

This is breaking my build, any suggestions (tried deleting package-lock & node_modules) or I have to just wait for the upgrade?

@trent-abc You need to use ts-jest 27.

npm install -D ts-jest@27

Yes but the way this is made currently feels like a pain, 1 package that updates, then one vue package that follows up, then the vue-cli-plugin package that needs to follow up. A big chain of update..

Either version range should be more lax in the vue-cli-plugin or there should be autoupgrades with renovate, otherwise updates takes months before they make it to the vue-cli plugin

It's the same issue with eslint

any good news?

This is holding up our upgrades to Jest 28.

vue-jest added support for the Githubissues.

Githubissues is a development platform for aggregating issues.
