Describe the bug

Objective: I want to test an API via useFetch from Vuetify components.

Error occurrence: To achieve this goal, I've used '@nuxt/test-utils/runtime'. However, I encountered errors in the logs. To identify the cause, I've minimized the provided repository. As a result, it seems that an error occurs when "index.vue" is imported and used. Previously, I was using 'import { defineConfig } from "vite";' in vitest.config.ts and there were no errors in the logs at that time.

Both <templage> <script> are present in index.vue. Could you please advise me on this.

Additional context

As a solution for related errors, you can remove Vue() from the plugin in the vite.config.m{ts|js} file.
If you remove Vue() from plugins in the vitest.config.m{ts|js} file it complains Vuetify needs to be loaded before the Vue plugin.

No response
