Support for own Electron version / instance

[ChrisKuBa]

Hi,

How can I configure Cypress to use my own electron version / installation?
Because the version of electron is bundled with cypress outdated and also we ship our own fixed version of electron, its necessary to test against a specific electron version.

I try to inject a new browser config, but cypress will not connect. The path to the electron.exe ist valid in my configuration, but no process will start / the process exits with 4294967295.

import { defineConfig } from 'cypress';

import Browser = Cypress.Browser;

const addLocalElectonConfig = (browsersConfig: Browser[]): Browser[] => [
    ...browsersConfig,
    {
        name: 'electron-locale',
        channel: 'stable',
        family: 'chromium',
        displayName: 'Electron Local',
        version: '126.0.6478.36',
        path: 'C:\\...\\node_modules\\electron\\dist\\electron.exe',
        majorVersion: '126',
        isHeaded: true,
        isHeadless: false,
    },
];

export default defineConfig({
    component: {
        setupNodeEvents(on, config) {
            return {
                ...config,
                browsers: addLocalElectonConfig(config.browsers),
            };
        },
    },
    e2e: {
        setupNodeEvents(on, config) {
            return {
                ...config,
                browsers: addLocalElectonConfig(config.browsers),
            };
        },
    },
});
