Test Electron app with k6 browser

[ankur22]

Feature Description

At the moment there is no way to run k6 browser against an electron app. We can start a websocket devtools connection, and connect to it, but there is no way to retrieve the current browserContext or page that the electron app is displaying.

Steps to reproduce the current state are:

1. Clone https://github.com/electron/electron-quick-start
2. npm install
3. Add the lines from https://github.com/electron/electron/blob/main/docs/api/command-line-switches.md
4. npm start
5. Copy the ws connection that is printed
6. try to run a simple k6 browser test, it soon becomes clear that we won't be able to retrieve the existing page that the electron app is displaying. e.g. K6_BROWSER_WS_URL=ws://127.0.0.1:8315/devtools/browser/b62d813a-97b6-4307-adb2-69f2c5c86f53 k6 run electron.js

import { browser } from 'k6/browser'

export const options = {
  scenarios: {
    ui: {
      executor: 'shared-iterations',
      options: {
        browser: {
          type: 'chromium',
        },
      },
    },
  },
}

export default async function () {
  const page = await browser.newPage()
  await page.close()
}
