How To Run Selenium With Chrome In Docker

You need to launch a standalone chrome browser

docker run -d -p 4444:4444 selenium/standalone-chrome

and then in your python script launch browser using Remote webdriver

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote("http://127.0.0.1:4444/wd/hub", DesiredCapabilities.CHROME)

If you want you can also launch a Selenium Grid hub.

To do this as a django test do the following:

# docker-compose.yml

selenium:
  image: selenium/standalone-firefox
  ports:
  - 4444:4444

# project/app/test.py

from django.test import TestCase
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities


class SiteTest(TestCase):
    fixtures = [
        'app/fixtures/app.json',
        ...
    ]

    def setUp(self):
        self.browser = webdriver.Remote("http://selenium:4444/wd/hub", DesiredCapabilities.FIREFOX)

    def tearDown(self):
        self.browser.quit()

    def test_visit_site(self):
        self.browser.get('http://app:8000/')
        self.assertIn(self.browser.title, 'Home')

Note:

If you use webdriver.ChromeOptions|FirefoxOptions|etc then DesiredCapabalities import is not necessary:

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_argument('--headless')  # example
driver = webdriver.Remote("http://127.0.0.1:4444/wd/hub", options=options)
