electron-chromedriver

Runs an instance of electron-chromedriver as a Docker container and includes a VNC server to watch the tests run.

In a nutshell you build your app, mount the build folder as a volume inside this Docker container using docker-compose then configure an instance of Selenium Webdriver to connect to chromedriver inside the container and run your tests.

Currently only works on Linux hosts as it requires fuse inside the container.

How to use

Create a docker-compose.yml file similar to the following:

chromedriver:
  image: achingbrain/electron-chromedriver:1.7.1
  volumes:
    - /dev/fuse:/dev/fuse
    - ./build:/app # Your app will be available in the /app dir in the container
  environment:
    SCREEN_WIDTH: 1920
    SCREEN_HEIGHT: 1080
    # Other configuration options here
  ports:
    - "9515:9515" # Chromedriver port, host:container
    - "5900:5900" # VNC server port, host:container
  cap_add:
    - SYS_ADMIN
  privileged: true

Configure electron-chromedriver with the following env vars:

CHROMEDRIVER_PORT 9515
CHROMEDRIVER_WHITELISTED_IPS ""
CHROMEDRIVER_OPTS
SCREEN_WIDTH 1920
SCREEN_HEIGHT 1080
SCREEN_DEPTH 24

Finally create a driver and use it to run your tests:

const webdriver = require('selenium-webdriver')

const driver = new webdriver.Builder()
  .usingServer('http://localhost:9515')
  .withCapabilities({
    chromeOptions: {
      binary: '/app/path-to-my-app'
    }
  })
  .forBrowser('electron')
  .build()

The port in the URL passed to usingServer should match the host port that the container's port 9515 is mapped to (9515 by default) and the path to the binary should be changed to match where your app's binary is, e.g. /app/My App-1.0.0-x86_64.AppImage or similar.

VNC Server

There is a built in VNC server running inside the container on port 5900 by default. To connect, use the password secret.

E.g:

$ vncviewer localhost::5900
# when prompted, enter the password 'secret'
