The
selenium
package is used to automate web browser interaction from Python.

Several browsers/drivers are supported (Firefox, Chrome, Internet Explorer), as well as the Remote protocol.
Supported Python Versions
Python 3.7+
Installing
If you have
pip
on your system, you can simply install or upgrade the Python bindings:
pip install -U selenium
Alternately, you can download the source distribution from
PyPI
(e.g. selenium-4.11.2.tar.gz), unarchive it, and run:
python setup.py install
Note: You may want to consider using
virtualenv
to create isolated Python environments.
Drivers
Selenium requires a driver to interface with the chosen browser. Firefox,
for example, requires
geckodriver
, which needs to be installed before the below examples can be run. Make sure it’s in your
PATH
, e. g., place it in
/usr/bin
or
/usr/local/bin
.
Failure to observe this step will give you an error
selenium.common.exceptions.WebDriverException: Message: ‘geckodriver’ executable needs to be in PATH.
Other supported browsers will have their own drivers available. Links to some of the more popular browser drivers follow.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get('http://www.yahoo.com')
assert 'Yahoo' in browser.title
elem = browser.find_element(By.NAME, 'p') # Find the search box
elem.send_keys('seleniumhq' + Keys.RETURN)
browser.quit()
Example 2:
Selenium WebDriver is often used as a basis for testing web applications. Here is a simple example using Python’s standard
unittest
library:
import unittest
from selenium import webdriver
class GoogleTestCase(unittest.TestCase):
def setUp(self):
self.browser = webdriver.Firefox()
self.addCleanup(self.browser.quit)
def test_page_title(self):
self.browser.get('http://www.google.com')
self.assertIn('Google', self.browser.title)
if __name__ == '__main__':
unittest.main(verbosity=2)
Selenium Server (optional)
For normal WebDriver scripts (non-Remote), the Java server is not needed.
However, to use Selenium Webdriver Remote , you need to also run the Selenium server. The server requires a Java Runtime Environment (JRE).
Download the server separately, from:
https://www.selenium.dev/downloads/
Run the server from the command line:
java -jar selenium-server-4.11.0.jar
Then run your Python client scripts.

Create a branch for your work
Ensure
tox
is installed (using a
virtualenv
is recommended)
python3.7 -m venv .venv && . .venv/bin/activate && pip install tox
After making changes, before committing execute
tox -e linting
If tox exits
0
, commit and push otherwise fix the newly introduced breakages.

will often rewrite the breakages automatically, however the files are unstaged and should staged again.
