Extension doesn't resolve Nuxt 3 aliases

[TheDutchCoder]

Describe the bug

When running vitest through the extension, it will fail to resolve paths like ~/utils and other ones using ~, which is an alias that's available in Nuxt.

Running vitest in the CLI has no issues with this.

Manually adding aliasses to tsconfig or vitest's config have no effect.

Example of the extension failing

Example of CLI working just fine:

Additional info: the CLI version also doesn't work when ran from the root with vitest directly, only when fed the config file.
Is this an issue with vitest itself then?

I encountered the same issue and resolved it by removing Vitest from the project folders and placing it only in the root of the monorepo. This made my workspace cleaner, and the VS Code extension started running all tests correctly. Additionally, because Vitest was not installed at the project level anymore, I was able to move all "test dependencies" to the root.

This is how my package.json in the root now looks like:

  "devDependencies": {
    "@cecalc/eslint-config": "workspace:*",
    "@nuxt/test-utils": "^3.15.1",
    "@turbo/gen": "^2.3.3",
    "@vitest/coverage-v8": "^2.1.8",
    "@vitest/ui": "2.1.8",
    "@vitest/web-worker": "2.1.8",
    "eslint": "^9.17.0",
    "happy-dom": "^15.0.0",
    "nuxt": "3.14.1592",
    "turbo": "^2.3.3",
    "typescript": "^5.7.2",
    "vite": "^5.0.0",
    "vitest": "^2.1.8",
    "vitest-environment-nuxt": "^1.0.1"
  }

I have no idea what happened, but it worked.

One more thing: I can still run tests locally through the CLI.
