By default, we always run your tests on Selenium 2.53.1, to ensure maximum performance and stability. Some customers however like to run their tests on an older/newer version of Selenium. This is now possible by [specifying the desired Selenium version](https://testingbot.com/support/web-automate/selenium/test-options#seleniumversion) in the desired capabilities option. For example this Python snippet which will run the test on Selenium 2.31.0 ```python import unittest from selenium import webdriver from testingbot import driver class Selenium2TestingBot(unittest.TestCase): def setUp(self): desired_capabilities = webdriver.DesiredCapabilities.FIREFOX desired_capabilities['version'] = 'latest' desired_capabilities['platform'] = 'WINDOWS' desired_capabilities['name'] = 'Testing Selenium 2 in Python' desired_capabilities['selenium-version'] = '2.31.0' self.driver = webdriver.Remote( desired_capabilities=desired_capabilities, command_executor="http://key:secret@hub.testingbot.com/wd/hub" ) self.driver.implicitly_wait(30) def test_google(self): self.driver.get('http://www.google.com') assert "Google" in self.driver.title def tearDown(self): self.driver.quit() unittest.TestCase.tearDown(self) if __name__ == ' __main__': unittest.main() ``` [← Previous post TestingBot has moved to its own cloud!](https://testingbot.com/blog/2013/12/06/testingbot-has-moved-to-its-own-cloud) [Next post → 2014 for TestingBot](https://testingbot.com/blog/2014/12/29/2014-for-testingbot) ## Sidebar ### TestingBot Cloud Testing Run automated, manual and visual tests on remote browsers and devices.
