I'm currently working on automatic installation of GUI application using library UIAutomation PS Extensions (https://uiautomation.codeplex.com/). It works pretty well in cases, when I run it against existing Windows user session. I run my PS script, it opens a window and I can click on buttons and so on ..

However, problem raises when this library is called from remote machine. I call my script (which should open a GUI window and start controlling it) via PsExec from remote machine. This causes that script is not able to open GUI window on remote machine and starts to produce various exceptions.
As workaround for this, I can make PsExec to connect to specific existing session on remote host, but unfortunatelly this is not stable as I can't guarantee session's existence.

Does enyone know whether it's possible to force PowerShell to open new session (interactive GUI) through which I would be able to call UIAutomation commands?

Thank in advance Matthew

I'm not clear on whether it's feasible to remotely open a new interactive desktop session in which to run GUI tests that require one. I'd be interested to find out if it's doable, since problems like this frequently come up when folks try to set up CI tests of Windows GUI apps.

Alternatively, I'd propose solving this by configuring the machine where your tests run to log in as a user at boot. Then you can remotely launch your tests as that user, and make use of their open session. That's worked in the past for me when I've run into similar issues.

  • Hi Bill, thanks for the hint. That's exactly solution we will probably go for. I created proof-of-concept where I leveraged already opened session on remote host. We can setup automatic login automatically when virtual machine starts. However, in my eyes, it's far more reliable to be able to open interactive GUI session ad-hoc. I'll be looking into possibilities of New-PSSession and Enter-PSSession cmdlets, whether they can be helpful. – Martinecko Apr 25 '15 at 19:24

    Just and update, it's not possible to control UI elements while in interactive session opened via Enter-PSSession. – Martinecko Apr 30 '15 at 12:55
