I hope you're doing well,

I'm trying to run selenium test with no GUI and no browser, I found this code:

#!/usr/bin/env python

from pyvirtualdisplay import Display
from selenium import webdriver

display = Display(visible=0, size=(800, 600))
display.start()

# now Firefox will run in a virtual display.
# you will not see the browser.
browser = webdriver.Firefox()
browser.get('http://www.google.com')
print(browser.title)
browser.quit()

display.stop()

But I'm getting the following error:

Traceback (most recent call last):
  File "test.py", line 11, in <module>
    browser = webdriver.Firefox()
  File "/home/developer/python3.7/lib/python3.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 201, in __init__

    raise exception_class(message, screen, stacktrace)

In the gekodriver log this is the error:

Do you know, how can I run a test in a Linux machine that doesn't have GUI.

Regards!

There're many docs related to running Selenium headless i.e. without a GUI. Here's how I did it for Chrome:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument("--no-sandbox")
options.add_argument("--headless")
driver = webdriver.Chrome(options = options)

FirefoxOptions docs are here.

  • I Tried your code, but I'm getting an error: TTraceback (most recent call last): File "/var/www/html/dotcomStatus/scripts/test.py", line 6, in driver = webdriver.Chrome(options = options) File "/home/developer/python3.10/lib/python3.10/site-packages/selenium/webdriver/chrome/webdriver.py", line 84, in __init__ super().__init__( File "/home/developer/python3.10/lib/python3.10/site-packages/selenium/webdriver/chromium/webdriver.py", line 101, in __init__ self.service.start() – Jonathan Viana May 10 '23 at 22:25

  • Unsure about Firefox, but did you install Chrome driver? Then add this from selenium.webdriver.chrome.service import Service from selenium import webdriver service = Service(executable_path="/path/to/chromedriver") driver = webdriver.Chrome(service=service) – Cat Mai May 10 '23 at 22:46
