WinAppDriver Starting/Stopping Task in azure devops not working as expected

[vishnuprakash9845]

I am currently automating the UWP application, so in the azure devops I tried to Include the WinAppDriver task to start the WinAppDriver server. But when I check the VM where the tests will run(Self hosted agent), I dont see winappdriver running or anything like that.

Bit confused with this task and how it works, can anyone please help me.

Configured Task in Azure Devops

After running the Pipeline

Also when I tried to programmatically start the winappdriver like below its not working in VM, but working fine in Local machine where I build the code.

string winAppDriverPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86), @"Windows Application Driver\WinAppDriver.exe"); Process.Start(winAppDriverPath);

Are your tests working?

@vishnuprakash9845 Maybe something with rights... Is WinAppDriver starting manually on the same Agent with the same session as Agent running? Could you look manually at what happened on Agent when the Start WinnAppDriver task is running (This task starting Powershell console from which running WinAppDriver)? Could you post the Stop WinnAppDriver task log (because it displays a log of the WinAppDriver console)?

I ran into this and am trying to remember the steps I took to resolve:

Have you:

• turned on developer mode on the agent machine?
• Ensure that auto-logon is enabled when you create the machine?

And as @Shakevg mentioned above, the Winappdriver Stop task output would be useful as well.

@Shakevg

Sorry for my late reply. Had to relocate to differnt location due to Pandemic

tried all the possible ways to resolve not getting any lead on this. Any one on the community [@anunay1 , @Shakevg , @timheuer , @not-the-car ] please help me.

1. Yes WinAppDriver is launching when I start manually on the same agent machine [VM1] 2. When I run WinAppDriver manually everything works as normal with below logs screenshot. All Tests will pass

3. Posting the Stop WinAppDriver logs

@vishnuprakash9845 I suppose your desktop session is locked. Did you configure a Self-hosted agent according to instruction https://docs.microsoft.com/en-us/azure/devops/pipelines/test/ui-testing-considerations?view=azure-devops&tabs=mstest#visible-ui-mode? Can you check test running with active maximized RDP session? Could you provide the code sample that you are using?

[vishnuprakash9845]

@Shakevg Thank you for the quick turnaround.

I have configured the agent to run as service, now reconfigured as per the instructions from the document for autologon as per below image.

Triggered couple of tests, its running fine. Let me monitor for couple of days.

how to achieve active maximized RDP session? Are yo referring to set Display Configurations as per below image

Due to some copyrights I am not supposed to share the entire code base. but can share the app launch code

@vishnuprakash9845 how to achieve an active maximized RDP session? Are you referring to set Display Configurations as per below image I just mean open RDP and do not collapse it - check is it working or not. Then correctly close the session according to the instruction above and re-check. Also, I propose to delete "ms:waitForAppLaunch" option because per my experience it can cause problems.

I am not too sure about the error log. But I have encountered similar issue before: My test able to run when I remote to the machine, but not able to run if the machine without remote in.

I had add 1 devops task before test task, then it solve my issue. Maybe you can try to have a look.

Screen Resolution Utility

Just run this task before your test task, and see if it able to help.
