Run multiple browser drivers concurrently

To run several browser drivers at the same time, you can use Python Multiprocessing

import multiprocessing from selenium import webdriver from selenium.webdriver.chrome.options import Options def main(): # Number of browser drivers to start driver_count = 3 for i in range(0, driver_count): p = multiprocessing.Process(target=run) p.start() processes_list.append(p) for p in processes_list: p.join() def run(): chrome_options = webdriver.ChromeOptions() driver = webdriver.Chrome(options=chrome_options) driver.get("https://example.com") if __name__ == '__main__': main()

This second example wraps browser actions in functions.

It also demonstrates how to bypass a browser certificate warning. Disabling certificate checks is unsafe outside a controlled test environment.
