Hi there, My chromedriver.exe is terminated when I call ‘Close Browser’ step. Please double check again if your browser is closed completely or not, or there are multiple chromedriver instances on your side If you want to terminate chromedriver.exe anytime after execution, you can check on ‘Terminate Drivers’ option from **Project -\> Settings -\> Execution** Thanks Edited: @Russ_Thomas ---

Same here, after running many testcases, I have a large numbers of chromedrivers.exe still running. I use WebUI.closeBrowser() and it does close the browser, but let the driver run. ---

Create a custom keyword as below and call it either at end or at the beginning of the test case. This will kill all instances of chrome.exe and chrome driver.exe public class killProcess{ @Keyword def killProcess() { Runtime.getRuntime().exec(“taskkill /im chromedriver.exe /f”) Runtime.getRuntime().exec(“taskkill /im chrome.exe /f”) } } ---

Personally, I prefer to keep this kind of thing out of my tests. I have a batch script which I run when needed. It contains just three lines, one for each webdriver module: ``` taskkill /f /im geckodriver.exe taskkill /f /im chromedriver.exe taskkill /f /im IEDriverServer.exe ``` ---

Hi Russ, Thanks for your feed-back. I use a similar batch script as well. I don’t always remember to run the script so I was thinking it might be good to add a keyword to kill the driver(s) when I call my single logoff case. Also I use Windows Scheduler to run cases over-night so having the killProcess will help for that testing. Cheers, Dave **Found the solution (I had to use single quotes):** public class killProcess { @Keyword def KILLWebdriver() { Runtime.getRuntime().exec(‘taskkill /f /im chrome.exe’) Runtime.getRuntime().exec(‘taskkill /f /im chromedriver.exe’) Runtime.getRuntime().exec(‘taskkill /f /im geckodriver.exe’) Runtime.getRuntime().exec(‘taskkill /f /im IEDriverServer.exe’) Runtime.getRuntime().exec(‘taskkill /f /im firefox.exe’) } } ---
