Add option to exclude all files and folders mentioned in `.gitignore` about vitest HOT 5 CLOSED

What exactly is the use case for this?

• Do you have test files that are listed in .gitignore and Vitest keeps running those tests?
• Do you have source files that are listed in .gitignore and also imported by tests or other sources files, and changing those ignored files ends up re-running the tests?

If you want to have all files from .gitignore not be considered a test file (exclude option only affects test file glob matching), you can use parse-gitignore package:

import { configDefaults, defineConfig } from 'vitest/config'
import gitignore from 'parse-gitignore'
import { readFileSync } from 'node:fs'

export default defineConfig({
  test: {
    exclude: [
      ...configDefaults, 
      ...parse(readFileSync('.gitignore', 'utf-8')),
    ],
  },
})

The situation that prompted me to open this issue was that files inside .direnv are picked up by vitest. I'm not super familiar with direnv, but it appears that source files get linked/mirrored within it.

So instead of just testing

src/static/js/__tests__/my-file.test.ts`

vitest will also attempt to test

.direnv/flake-inputs/sidsuihfuefhb/src/static/js/__tests__/my-file.test.ts`

Since the direnv is already in .gitignore, it would have been nice if the folder got excluded automatically as well.

Oh, good idea, thank you!

.gitignore is not related to testing, so I don't think we can have a built-in switch. You can still use custom solutions as I mentioned.
