  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

Build step 'Execute shell' marked build as failure
Finished: FAILURE

seems webdriver couldn't start, not sure how can i fix this issue and run selenium on jeninks. new to automation, pls advise thanks!

Solution

Try adding the below on your selenium test script :

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-dev-shm-usage")
chrome_options.add_argument('--headless')
