[Ruby] Selenium Webdriver + IE + Jenkins, blank screenshot of web application page

[Vid]

Hi,

We are using selenium webdriver with cucumber and ruby for automation testing of our web application. We execute our tests through Jenkins.

We are facing an issue while taking screenshot during test execution on IE, the screenshot comes black. However, there is no issue when we run tests on IE on local machine (without Jenkins). Also, we are able to successfully take screenshots on firefox through Jenkins.

Could anyone help with this issue please?

Thanks.
Divya

I would guess your screen is locked, the user running IE tests needs to
be logged in and the screen can't be locked if you want screenshots.

Mark,
We are running tests through Jenkins so tests automatically are headless. Does locking of machine matter in this case?

Windows can't be headless, you always need to be logged into a GUI somewhere.

Your Jenkins slave will need to be logged in and the screen not locked if you want screenshots (I'm assuming you're not using a windows machine as your Jenkins server).

We are using windows machines as Jenkins server and slaves.

[fmtjatt]

We are facing same problem here. We are using Windows Server 2003 for Jenkins which connects to Slave VM(Windows 7) to execute our tests. All the screenshots are blank and we haven't figured out how to make jenkins unlock the Slave machine so screenshots can be captured.

Can anyone please suggest something.This issue is still open.

My guess would be the same as Mark said. I am not sure why you get screenshots on FF, but as far as IE is concerned I would suspect issues with GUI session.

From what I experienced in the past you get screenshots when user is logged in (as Mark said, you always need to be logged in into GUI) but screen is locked. So when you:

 - log in, then use Start->Switch user

 - log in, then Start->Lock (or when Lock happens automatically after some time of inactivity - typical policy for for corporate Win machines)

 - log in with RDP and then close RDP connection  (when closing RDP connection win gui session is locked automatically)

If either of those is true, you need to :

 - turn off automatic Locking of the screen

 - install VNC on windows machines

 - stop using RDP and connect with VNC client to them

Different browsers, different technology.

IE is hooked into the OS in many ways, I would guess that if the OS is not rendering a GUI then IE will not render it either. 

The reason other browsers will work is that they will always be rendering the page internally and the Selenium screenshot mechanism uses this as the source for the screenshot, not what is displayed on screen. (That's why you don't see the mouse cursor, or dialogue boxes covering the browser, etc when you take a screenshot)

Thanks Mark.Atleast now I know the reason :)

This worked for me - http://ausavchuk.blogspot.ru/2013/05/screenshots-for-headless-configuration.html

Specifically, setting "Allow service to interact with desktop" for my Tomcat service (Start > Run > services.msc):

2. if you use service-based configuration you _need_ to set "Allow service to interact with desktop" option enabled for the service. Otherwise service can not interact with desktop.
