Integration Testing for Electron-Forge with WebdriverIO -- 2

How to Write Tests for an Electron-Forge + Vite + Vue Project Using WebdriverIO?
I'm working on an Electron-Forge project with Vite and Vue (https://github.com/alessandro-candon/stashbox) and trying to set up tests using WebdriverIO.

When I run npm run wdio, the process starts well, but I encounter the following error:

Uncaught Exception:
stashbox/src/main.js:1
import {app, BrowserWindow} from 'electron';
^^^^^
SyntaxError: Cannot use import statement outside a module

at ModuleWrap.<anonymous> (node:internal/modules/esm/translators:286:7)
at ModuleJob.run (node:internal/modules/esm/module_job:234:25)

My final need is to write easily tests for this utility : src/main/gcp/bucket.js to write a file in the fake-gcp-storage.

*** The final request will be made a PR on my project with a single working test for the utility bucket.js and of course, the app must still running.***
