Electron has removed remote module, and move it to electron-userland at @electron/remote. The last version of Spectron need to migrate to @electron/remote but there is an issue when Spectron includes the module.

const path = require('path');
const remoteMain = require('@electron/remote/main');
const WebDriver = require('webdriverio');

The code above is from spectron/lib/application.js. It shows the line of code that includes module from @electron/remote/main

const get_electron_binding_1 = require("../common/get-electron-binding");
const v8Util = get_electron_binding_1.getElectronBinding('v8_util');

The code above is from server.ts in @electron/remote/main/, it calls getElectronBinding('v8_util').

const getElectronBinding = (name) => {
    if (process._linkedBinding) {
        return process._linkedBinding('electron_common_' + name);
    }
    ...
};

The code above is function getElectronBinding that call _linkedBinding. This code will throw an error and the debugging ends here.

Here is the full error message.

Debugger attached.
