confirm about error :The operation cannot be performed, because the user session is disconnect

Hi,

This is not a limitation of TestComplete but essential behavior of Windows OS that active unlocked user session must exist in order GUI application can render its interface. Without graphical interface  been rendered, UI objects do not exist and thus TestComplete cannot find them.

There might be more than one way to provide unlocked user session and TC's documentation describes probably one of the most generic ways of how this can be done.

I suggest you read through Running Tests via Remote Desktop? And understand how tscon utility works.

See posts, https://community.smartbear.com/t5/TestComplete-Questions/Desktop-invisible-error-when-system-is-locked-while-running/m-p/250573 and https://community.smartbear.com/t5/TestComplete-Questions/Getting-quot-The-object-does-not-exist-quot-errors-for-all/m-p/245442.

I've come up with a WSL2 solution.
WSL with Ubuntu and remmina app preconfigured to connect to the test environment
The script below is run from the pipeline to activate remmina session

REMINNA_FILE_PATH= 'PATH TO YOUR .remmina FILE HERE'
EXPECTED_ERROR='PDU_TYPE_DATA'

echo $(date)'Started *** *** *** *** *** *** *** ***'
cat /dev/null >nohup.out
nohup remmina $REMINNA_FILE_PATH & disown

if timeout 30 tail -n 100 -f ./nohup.out | grep --line-buffered -m 1 $EXPECTED_ERROR; then
  echo $(date) $EXPECTED_ERROR 'catched' $RVALUE
  cat /dev/null >nohup.out
  exit 0
else
  echo $(date) $EXPECTED_ERROR 'not catched' $RVALUE
  cat /dev/null >nohup.out
  exit 1
fi

The issue I didn't figure out:
The script continues running while the session is active so I just set a 1-minute timeout for this operation in the pipeline.

BTW It would be cool If someone could give advice, on how to continue running the pipeline after the specific error was caught in the script

My setup:

I have a VM, and I will only use user 'UserX' to log into the machine to run the automation.

I have a batch file, which contains this statement only

for /f "skip=1 tokens=3" %%s in ('query user %USERNAME%') do (%windir%\System32\tscon.exe %%s /dest:console)

Running this batch file, will disconnect user 'UserX' that's logged on, but the session will remain active.

I have a task schedule setup on the VM, which I can trigger from my local machine using Computer Management (via Connect to another machine option) application. The task schedule runs a PowerShell script, similar to a batch file, which runs SessionCreator using parameters /UseActiveSession and /ScreenResolution:"1920*1080" (or I can run TestExecute)

Running:

From when the VM is restarted - I log onto the VM using user 'UserX', I then run the tscon batch file to disconnect 'UserX'. I then run the task schedule from my local machine, will which run SessionCreate (or TestExecute) on the VM using the active sessions of user 'UserX'.

If I log on the VM using 'UserX' and look at Task Manager, Users tab. I will see two active sessions.

When connected to your remote desktop machine, if you were to run your batch file (do not use tscon or logout), does it run? 

1. On your remote desktop machine, could you create a batch file that just contains this statement (ensure %1 and %2 are populated)

"c:\Automation\x64\Bin\TestComplete.exe" "E:\AutomationTest\APPLE\AppleWMS_Test\AppleWMS_Test.pjs" /run /project:"Apple_Test" /ExportLog:"%1" /ExportSummary:"%2" /SilentMode /exit

Can you run your batch file, to ensure that your automation works?

2. Can you create a task schedule, that will run the above batch file Can you run this task schedule, to ensure your automation works? 

3. Could you create another batch file that just contains this statement

for /f "skip=1 tokens=3" %%s in ('query user %USERNAME%') do (%windir%\System32\tscon.exe %%s /dest:console)

Can you run this batch file, which will disconnect your sessions.

4. Using your local machine, launch Computer Management, click Actions and select 'Connect to another computer...'. Enter your remote desktop machine name. Once connected, can you run the task schedule that you created in Step 2. Check that your automation has run on the remote desktop machine (look at the ExportLog and ExportSummary results)

I want you to test the above scenarios to ensure that they work. 

Log onto your VM, and launch the task schedule (step 4) from your local machine, you will see the automation running on the VM, and you should then be able to diagnose any issues.

Your VM screen resolution may be of a different size when disconnected, so the image repository will most likely fail. You can within your keyword test, output the screen resolution

Log.Message("Resolution: " + Sys.Desktop.Width + "x" + Sys.Desktop.Height);

to ensure it's what you expect.

As mentioned previous, I use SessionCreator using parameters /UseActiveSession and /ScreenResolution:"1920*1080".

If you were to run Step 4, your automation should run and at least output to the log file, the resolution.

What is the purpose, in your instance, of using the image repository?

Are you not able to identify the object, using the Object Spy tool?

Can the Object Spy tool not identify that link in your "Item Description" column? Also, links are usually single click.

You should check whether your application is supported by TestComplete, see Supported Technologies and Applications. 

With image based, you need to ensure your environment is correctly setup - e.g. resolution, colour, scaling etc.
