latest selenium-webdriver no longer works with electron

🐛 Bug Report

Running tests in electron using latest selenium-webdriver no longer works in selenium-webdriver 4.0.0-beta.1. They result in

(node:20272) UnhandledPromiseRejectionWarning: SessionNotCreatedError: session not created: No matching capabilities found
    at Object.throwDecodedError (C:\Downloads\MyCode\node_modules\selenium-webdriver\lib\error.js:517:15)
    at parseHttpResponse (C:\Downloads\MyCode\node_modules\selenium-webdriver\lib\http.js:671:13)

    at processTicksAndRejections (internal/process/task_queues.js:97:5)

This used to work with selenium-webdriver 3.4.0. I am unsure whether this should be resolved in selenium, electron or chromedriver. Any input is appreciated.

To Reproduce

Detailed steps to reproduce the behavior:

• Follow instructions from https://www.electronjs.org/docs/tutorial/using-selenium-and-webdriver under ‘Setting up with WebDriverJs’. The sample code works with selenium-webdriver 3.4.0 but not with 4.0.0-beta.1.

Expected behavior

I was hoping testing with electron would still work.

Test script or set of commands reproducing this issue

const ChildProcess = require('child_process');
const chromedriver = require('chromedriver');

const chromedriverProcess = ChildProcess.spawn(
    chromedriver.path, // process path goes here
    [], // arguments go here
    {
        stdio: 'inherit'
    }
);
const electronBinary = 'MyElectronBinary.exe';
const driver = new webdriver.Builder()
    // The "9515" is the port opened by chrome driver.
    .usingServer('http://localhost:9515')
    .withCapabilities({
        chromeOptions: {
            // Here is the path to your Electron binary.
            binary: electronBinary
        }
    })
    .forBrowser('electron')
    .build();

driver.get('http://www.google.com');
driver.findElement(webdriver.By.name('q')).sendKeys('webdriver');
driver.findElement(webdriver.By.name('btnG')).click();
driver.wait(() => {
    return driver.getTitle().then((title) => {
        return title === 'webdriver - Google Search';
    });
}, 1000);

driver.quit();

Environment

OS: Windows 10.0.19042 Build 19042 Browser: electron (chromedriver) Browser version: electron 10.1.3 Browser Driver version: 85.0.4183.38 (9047dbc2c693f044042bbec5c91401c708c7c26a-refs/branch-heads/4183@{#779}) Language Bindings version: nodejs 12.14.1 Selenium Grid version (if applicable): /

Thanks Diego! It indeed works when changing to “goog:chromeOptions” and “forBrowser(‘chrome’)”!

Ok, so not sure if this is an Electron or ChromeDriver issue, but I was able to run a small script and have things working. The main change, aside of being sure the ChromeDriver version is the right one for the Electron app, was: .forBrowser('chrome')

Complete setup can be seen here.

I am going to close this and keep an eye on https://github.com/electron/electron/issues/28197 in case something is needed on the Selenium WebDriver side.
