Selenium : How To Stop Geckodriver Process Impacting Pc Memory, Without Calling Driver.quit()?

There is a test, smth like: import //needed imports public class TestClass{ WebDriver driver; @Before public void setUp() { //some code } @Test

Solution 1:

As per your question commenting out driver.quit() just Not to close firefox window after each run, because I just want to analyse what I have won't be a part of best practices.

For any detailed analysis we can create log entries and take snapshots.

While automating through Selenium as per the best practices you should invoke the quit() method within the tearDown() {}. Invoking quit()DELETEs the current browsing session through sending "quit" command with {"flags":["eForceQuit"]} and finally sends the GET request on /shutdownEndPoint. Here is an example below :

1503397488598   webdriver::server   DEBUG   -> DELETE /session/8e457516-3335-4d3b-9140-53fb52aa8b74 
1503397488607   geckodriver::marionette TRACE   ->37:[0,4,"quit",{"flags":["eForceQuit"]}]
1503397488821   webdriver::server   DEBUG   -> GET /shutdown

So on invoking quit() method the Web Browser session and the WebDriver instance gets killed completely. Hence you don't have to incorporate any additional steps which will be an overhead.

Solution

Still if you want to execute kill the dangling WebDriver instances e.g. GeckoDriver.exe instances you can use either of the following code block to kill any of the dangling WebDriver instances :

• Java Solution(Windows):

  import java.io.IOException;
  
  publicclassKill_ChromeDriver_GeckoDriver_IEDriverserver 
  {
      publicstaticvoidmain(String[] args)throws Exception 
      {
          Runtime.getRuntime().exec("taskkill /F /IM geckodriver.exe /T");
          Runtime.getRuntime().exec("taskkill /F /IM chromedriver.exe /T");
          Runtime.getRuntime().exec("taskkill /F /IM IEDriverServer.exe /T");
      }
  }
  

• Python Solution (Windows):

  import osos.system("taskkill /f /im geckodriver.exe /T")
  os.system("taskkill /f /im chromedriver.exe /T")
  os.system("taskkill /f /im IEDriverServer.exe /T")
  

• Python Solution(Cross Platform):

  import os
  import psutil
  
  PROCNAME = "geckodriver"# or chromedriver or IEDriverServerforprocin psutil.process_iter():
      # check whether the process name matchesifproc.name() == PROCNAME:proc.kill()
