Nuxt Vitest page unit testing with SSR: false

Question

I am trying to performed End to End testing on my index.vue page according to the documentation. My project requires that SSR is false but, when disabled, my Vitest unit tests fail.

This is my index.nuxt.test.js file:

import { describe, expect, it } from 'vitest'
import { setup, $fetch } from '@nuxt/test-utils'

describe('The page starts up', async () => {
  await setup({
    rootDir: '../',
    server: true
  })

  it('contains "welcome to the homepage"', async () => {
    expect(await $fetch('/')).toMatch('homepage')
  })
})

Logging the fetch results shows that the fetched HTML in SPA mode is a static page that I assume is hydrated later, so Vitest cannot match the word "homepage" in it. How can I unit test the fully hydrated page?

I have tried using mountSuspended from the docs, but now it seems to error because of the I18n module I'm using with Nuxt
