Ability to avoid a new nuxt instance for each test file

Describe the feature

I have a project where I've written multiple test files, each with their own setup() inside the top describe()

describe('/api/pen', async () => {
  await setup(setupConfig())
...

When I run these tests it creates a nuxt instance for each test file, demonstrated here: https://github.com/fumeapp/bio/actions/runs/10505024117/job/29101731333#step:12:48

I'm not sure if I have this setup incorrectly, or maybe if there was a way to have all test files share the same nuxt instance?

P.S. I am working on a potential GH action version that will run nuxt in the background and allow a possible setup({host: ...}) version, if i get this working i'll share it.

• Could this feature be implemented as a module?

Final checks

• Read the contribution guide.
• Check existing discussions and issues.

Start by examining how setup() initializes Nuxt for each test file and reproduce the behavior with the linked project or workflow run. Define how multiple test files can share one Nuxt instance while retaining their setup() calls, then verify the approach with the test suite.
