I have my selenium webdriver tests on EC2. Chrome --headless flag is on and job is started from Jenkins. Is there a way to watch the live UI tests on the browser window via a VNC connection from my local machine like how it's done on Selenium GRID?

I do not want to use Selenium Grid at the moment.

There are two issues you need to think about;

  1. You are running on headless mode, so there should be no visible Chrome window. You may need to disable it.

  2. If the Jenkins initiated the job; you can see the Chrome window, only if you VNC with Jenkins user, not another account/user.

  • I tried VNC option witout headless flag and here's where I am stuck at now. Any help would be really appreciated. Here's a detailed explanation of my issue. stackoverflow.com/q/63935935/4113833

  • On the code side, I'm using webdriver as driver=new ChromeDriver (path): and not remotedriver(EC2 IP)/wd/hud. Was thinking of using remotedriver as next debugging step. *Please excuse the syntax, commenting from my phone.
