"vitest --ui" causing "Error: spawn xdg-open ENOENT"

I'm trying to check out Vitest's fancy UI server in my node docker container. But can't get it up and running. When running the npm script vitest --ui I get a node error spawn xdg-open ENOENT.

Here the full error message:

$ npm run test-ui

> [email protected] test-ui
> vitest --ui


 DEV  v0.23.4 /home/node/apps/main/frontend
      UI started at http://localhost:51204/__vitest__/

node:events:491
      throw er; // Unhandled 'error' event
      ^

  code: 'ENOENT',
  syscall: 'spawn xdg-open',
  path: 'xdg-open',
  spawnargs: [ 'https://localhost:51204/__vitest__/' ]
}

Node.js v18.10.0

Google is no help at all - nothing related to Vitest even close. Also I'm obviously not a Node.js expert.

If you are running your app in docker, make sure you open set to false in vite-config.ts

    server: {    
        host: true,
        port: 3000, 
        open: false
    }

and package.json only has "start": "vite" or "start": "vite --no-open"

If you want to open the FE in a browser, do this:

sudo apt install xdg-utils

If you don't want to open the UI, like in a server, edit your package.json file:

  ...
  "scripts": {
    "start": "vite --no-open",
    ...
  }
  ...

I was running SveltKit with pnpm, vite, and vitest...

Got the same error message without vitest --ui part ...

Solved by running it in docker without "--open"

CMD ["pnpm","run", "dev"]

Even though the Node.js error message appears pretty cryptic to me, I still was lucky to use Ubuntu as my primary OS (beside macOS) which made me draw my attention to xdg-open in the error message - I occasionally use the command to open all kind of programs/apps on Ubuntu. Don't know why, but you need to have xdg-open installed on your system, to be able to run vitest --ui, even though it's neither mentioned in Vitest nor in Vite Github repos with a single word. Anyway for debian based containers it's:

apt install xdg-utils --fix-missing

Allthough this made the ENOENT error go away and the UI server starts up without errors, I still don't get to see the UI app due to some runtime-dom errors... I give it up. But maybe someone else finds the xdg-open info helpful.

UPDATE: It's working!

I just had to append /__vitest__/ to my proxied local url as clearly described in the docs:

"Then you can visit the Vitest UI at http://localhost:51204/__vitest__/"
