Web Driver
To start a web browser, the Selenium module needs a web driver.
Supported browsers are:

  • Chrome
  • Firefox
  • Internet Explorer
  • Safari
  • Opera
  • PhantomJS (invisible)

To start a browser, you will need to corresponding driver. The driver “ChromeDriver” is needed to start Chrome, “FirefoxDriver” for Firefox.

All drivers can be downloaded from: http://docs.seleniumhq.org/download/

Example code
Python will start and control the chromium browser using the code below:

from selenium import webdriver
import time
 
options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')
options.add_argument("--test-type")
options.binary_location = "/usr/bin/chromium"
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://python.org')

You can change the browser using:

# Firefox 
driver = webdriver.Firefox()
 
# Google Chrome 
driver = webdriver.Chrome()
 
# iPhone
driver = webdriver.Remote(browser_name="iphone", command_executor='http://172.24.101.36:3001/hub')
 
# Android
driver = webdriver.Remote(browser_name="android", command_executor='http://127.0.0.1:8080/hub')
