Add support for bun test runner testing on .vue SFC files

[nathanchase]

What is the problem this feature would solve?

I have many tests that are testing individual Vue single-file component (.vue) files in my Nuxt 3 project, and I'm currently leaning on nuxt-vitest for mounting and running tests in a Nuxt 3 environment using Vitest for my components.

I'd like to utilize Bun's test runner to test these .vue files, in addition to my TypeScript files (composables, etc.) and take advantage of Bun's test runner's speed. The syntax differences between Bun's test runner and vitest seems negligible, and both utilize happy-dom for DOM testing.

What is the feature you are proposing to solve the problem?

Enhance Bun's test runner to support testing Vue single file components, and Nuxt 3 environments.

What alternatives have you considered?

nuxt-vitest
