Thanks a lot for this @OrbisK! I did try before without success.. I've updated the PR to fix lint and added extends: true on both projects, can you confirm this is correct?

Also, would you know how to migrate to Vitest v4? When I try I get this error:

FAIL   vue  test/components/User.spec.ts [ test/components/User.spec.ts ]
Error: Cannot find module '/test/utils/mount' imported from '/Users/benjamincanac/GitHub/nuxt/ui/test/components/User.spec.ts'

@benjamincanac I think I have a "fix"

Tests are green but i get these logs:

BTW @nuxt/test-utils vitest 4 support is not merged yet: nuxt/test-utils#1481

---

My "fix":

[benjamincanac]

Oh yes you're right, we need to wait for @nuxt/test-utils support! I guess we can merge this as-is then and update once released with your fix?

[benjamincanac]

Thanks again! 😊
