Using Selenium and WebDriver

From ChromeDriver - WebDriver for Chrome:

WebDriver is an open source tool for automated testing of web apps across many browsers. It provides capabilities for navigating to web pages, user input, JavaScript execution, and more. ChromeDriver is a standalone server which implements WebDriver's wire protocol for Chromium. It is being developed by members of the Chromium and WebDriver teams.

In Electron's releases page you can find archives of chromedriver, there is no difference between Electron's distribution of chromedriver and upstream ones, so in order to use chromedriver together with Electron, you will need some special setup.

Also notice that only minor version update releases (e.g. vX.X.0 releases) include chromedriver archives, because chromedriver doesn't change as frequent as Electron itself.

Setting up with WebDriverJs

WebDriverJs provided a Node package for testing with web driver, we will use it as an example.

1. Start chrome driver

First you need to download the chromedriver binary, and run it:

$ ./chromedriver
Starting ChromeDriver (v2.10.291558) on port 9515
Only local connections are allowed.

Remember the port number 9515, which will be used later

2. Install WebDriverJS

$ npm install selenium-webdriver

3. Connect to chrome driver

The usage of selenium-webdriver with Electron is basically the same with upstream, except that you have to manually specify how to connect chrome driver and where to find Electron's binary:

var webdriver = require('selenium-webdriver');

var 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: '/Path-to-Your-App.app/Contents/MacOS/Atom'}})
  .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(function() {
 return driver.getTitle().then(function(title) {
   return title === 'webdriver - Google Search';
 });
}, 1000);

driver.quit();

Setting up with WebdriverIO

WebdriverIO provided a Node package for testing with web driver.

1. Start chrome driver

First you need to download the chromedriver binary, and run it:

$ chromedriver --url-base=/wd/hub --port=9515
Starting ChromeDriver (v2.10.291558) on port 9515
Only local connections are allowed.

Remember the port number 9515, which will be used later

2. Install WebDriverJS

$ npm install webdriverio

3. Connect to chrome driver

var webdriverio = require('webdriverio');
var options = {
	host: "localhost", // Use localhost as chrome driver server 
    port: 9515,        // "9515" is the port opened by chrome driver.
    desiredCapabilities: {
            browserName: 'chrome',
            chromeOptions: {binary: '/Path-to-Your-App.app/Electron'} // Path to your Electron binary.
        }
};

webdriverio
    .remote(options)
    .init()
    .url('http://google.com')
    .setValue('#q', 'webdriverio')
    .click('#btnG')
    .title(function(err, res) {
        console.log('Title was: ' + res.value);
    })
    .end();

Workflow

To test your application without rebuilding Electron, simply place your app source into Electron's resource directory.
