Get PID of Browser launched by selenium

Question

I would like to get the PID of the browser launched by selenium. Is there any way to get it done?

Answer 1

If you're using PhantomJS then you can get the PID from the process Popen object:

from selenium import webdriver
browser = webdriver.PhantomJS()
print browser.service.process.pid  

Answer 2

Using the Python API, it's pretty simple:

from selenium import webdriver
browser = webdriver.Firefox()
print browser.binary.process.pid
# browser.binary.process is a Popen object...

If you're using Chrome, it's a little more complex, you go via a chromedriver process:

c = webdriver.Chrome()
c.service.process # is a Popen instance for the chromedriver process
import psutil
p = psutil.Process(c.service.process.pid)
print p.get_children(recursive=True)

Answer 3

You can retrieve the PID of Browser Process launched by Selenium using python client in different ways as follows:

---

Firefox

Accessing the capabilities object which returns a dictionary using the following solution:

• Code Block:

  from selenium import webdriver
  from selenium.webdriver.firefox.options import Options
  
  options = Options()
  options.binary_location = r'C:\Program Files\Firefox Nightly\firefox.exe'
  driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\WebDrivers\geckodriver.exe')
  my_dict = driver.capabilities
  print("PID of the browser process is: " + str(my_dict['moz:processID']))
  

• Console Output:

  PID of the browser process is: 14240
  

• Browser Snapshot:

Chrome

Iterating through the processes using psutil.process_iter() where process.cmdline() contains --test-type=webdriver as follows:

• Code Block:

  from selenium import webdriver
  from contextlib import suppress
  import psutil
  
  driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://www.google.com/')
  for process in psutil.process_iter():
      if process.name() == 'chrome.exe' and '--test-type=webdriver' in process.cmdline():
      with suppress(psutil.NoSuchProcess):
          print(process.pid)
  

• Console Output:

  1164
  1724
  4380
  5748
