defineVitestConfig not respecting custom configFile

[mattkatt]

Im attempting to create a nuxt.config file for running tests (named nuxt-test.config), which contains additional configuration for running tests that I do not want in the build config. I am attempting to pass the name of the config file into defineVitestConfig, but when running vitest, it's still is using the default nuxt.config file, which is failing tests. If the appropriate configs are moved from the test config into the default then tests run fine.

Example error steps to duplicate:

1. Install nuxt-vitest into a fresh nuxt project
2. Create a new nuxt-test.config file containing the module import:

   export default defineNuxtConfig({
       modules: ['nuxt-vitest'],
   })
   

3. Create a vitest.config file using defineVitestConfig, passing in the following config:

   export default defineVitestConfig({
       configFile: 'nuxt-test.config',
   })
   

4. run vitest

This will cause vitest to error as it complains that the 'nuxt-vitest' module is not defined in 'nuxt.config'.

Yes, the configFile option there is a vite config file, rather than a nuxt one. Would you consider adding a local module which includes all your test config?

We could also support a custom nuxt config file but that's not that common in the rest of the Nuxt ecosystem.

It's now possible to define nuxt configuration overrides in your vitest config via test.environmentOptions.nuxt. Does that solve this issue for you?
