when selenium node is run as a Windows service, I get unable to discover open pages error

[ASK]

Hi,

I have looked around the net and this forum for the issue I am writing about and there seems to be a workaround of no-sandbox to be used. I am reluctant to use it because it is a WAR and I have to make sure that all the nodes get this change or all the tests are updated

In Chrome browser when selenium node is run as a Windows service, I get InitSession unknown error: unable to discover open pages

I am a Selenium newbie. In fact I am covering for another automation tester.

I am trying to setup Selenium Grid, I have successfully setup Hub and node. 

When I run Selenium node as a Windows Service, for chrome browser I get following error.

[0.535][INFO]: Launching chrome: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-component-update --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-logging --ignore-certificate-errors --load-extension="C:\Windows\TEMP\scoped_dir1396_19904\internal" --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12964 --safebrowsing-disable-auto-update --test-type --use-mock-keychain --user-data-dir="C:\Windows\TEMP\scoped_dir1396_21178" data:,

[60.676][INFO]: RESPONSE InitSession unknown error: unable to discover open pages

When I run node as a java program in command line (note - without windows service) it works fine. 

Service is running as system user and I want to run the service as system user so that browsers don't show up when I remote login to the machine. 

I have also tried it using a different admin account, the result is the same. 

These are the versions I am using

Selenium 2.53.1

Firefox version 45.2.0

Chrome Version  52.0.2743.82  (Chrome driver 2.22)

These are the commands I run to complete the setup. Note, I am using NSSM to setup Windows Services.

I am setting up node and hub on the same machine for the initial setup using following command.

C:\Selenium\nssm-2.24\win32\nssm.exe install GridNode java -Dwebdriver.chrome.driver="C:\Selenium\chromedriver-2.22\chromedriver.exe" -Dwebdriver.ie.driver="C:\Selenium\iedriver-2.53.1\IEDriverServer.exe" -jar C:\Selenium\selenium-server-standalone-2.53.1.jar -role webdriver -hub http://x.x.x.x:4444/grid/reg -Dwebdriver.chrome.logfile=C:\Selenium\chromedriver.log

Any help is appreciated.

When I add no-sandbox option, it works smoothly but I am thinking that this issue might be related to the system account and the privileges.

Ajith,

I think this is a bug with Chrome Browser itself.

I have added the bug links in this SO reply. Please see here : http://stackoverflow.com/a/38721806/679824

As Krishnan says this may be a bug with Chrome Browser

However, it may be worth upgrading Firefox to Firefox 47

As of 30 June 2016 Firefox 47 should be OK with Selenium 2.53.1

Andrew,

I think the OP is having issues with Chrome and not firefox. 

For Firefox, one needs to be using Firefox 47.0.1 with Selenium 2.53.1

Agreed: For Firefox, one needs to be using Firefox 47.0.1 with Selenium 2.53.1
