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.

Targeted Github：https://github.com/motoo1789/nuxt-test-utils_report

Reproduction

1. Import the Github into your local environment
2. Run npm install in the environment imported to local
3. Run npx vitest index

Logs

FAIL  tests/pages/index.test.ts [ tests/pages/index.test.ts ]

We have tried to deal with this issue here as a close problem.
The solution to this problem is to remove Vue() from the plugins in ‘vitest.config.ts’.
However, I get an error saying to load Vue() first because I am using vitest().

// vitest.config.ts   
import Vue from "@vitejs/plugin-vue";
import vuetify from 'vite-plugin-vuetify'
import path from 'path'
import { defineVitestConfig } from '@nuxt/test-utils/config'


export default defineVitestConfig({
  plugins: [
    // Vue(), error
    vuetify(),
  ],
  // and more ...
