Supported Python Versions

Supported Browsers

Several browsers are supported, as well as the Remote protocol:

Installing

If you have pip on your system, you can simply install or upgrade the Python bindings:

pip install -U selenium

You may want to consider using a virtual environmentto create isolated Python environments.

Drivers

Selenium requires a driver to interface with the chosen browser (chromedriver, edgedriver, geckodriver, etc).

In older versions of Selenium, it was necessary to install and manage these drivers yourself. You had to make sure the driver executable was available on your system PATH, or specified explicitly in code. Modern versions of Selenium handle browser and driver installation for you with Selenium Manager. You generally don’t have to worry about driver installation or configuration now that it’s done for you when you instantiate a WebDriver. Selenium Manager works with most supported platforms and browsers. If it doesn’t meet your needs, you can still install and specify browsers and drivers yourself.

Links to some of the more popular browser drivers:

Example 0:

from selenium import webdriver


driver = webdriver.Chrome()
driver.get('https://selenium.dev/')
driver.quit()

Example 1:

from selenium import webdriver
from selenium.webdriver.common.by import By


driver = webdriver.Chrome()

driver.get('https://selenium.dev/documentation')
assert 'Selenium' in driver.title

elem = driver.find_element(By.ID, 'm-documentationwebdriver')
elem.click()
assert 'WebDriver' in driver.title

driver.quit()

Example 2:

Selenium WebDriver is often used as a basis for testing web applications. Here is a simple example using Python’s standardunittest library:

import unittest
from selenium import webdriver


class GoogleTestCase(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()
        self.addCleanup(self.driver.quit)

    def test_page_title(self):
        self.driver.get('https://www.google.com')
        self.assertIn('Google', self.driver.title)

if __name__ == '__main__':
    unittest.main(verbosity=2)

Selenium Grid (optional)

For local Selenium scripts, the Java server is not needed.

To use Selenium remotely, you need to also run the Selenium grid. For information on running Selenium Grid: https://www.selenium.dev/documentation/grid/getting_started/

To use Remote WebDriver see: https://www.selenium.dev/documentation/webdriver/drivers/remote_webdriver/?tab=python
