python extension in remote connection is not setting TEST_RUN_PIPE

[msmitherdc]

Type: Bug

Behaviour

Traceback (most recent call last):
  File "/home/gridusr/.vscode-server-insiders/extensions/ms-python.python-2024.15.2024092502-linux-x64/python_files/unittestadapter/execution.py", line 274, in execute_eot_and_cleanup

    raise VSCodeUnittestError(error_msg)
unittestadapter.pvsc_utils.VSCodeUnittestError: UNITTEST ERROR: TEST_RUN_PIPE is not set at the time of unittest trying to send data. Please confirm this environment variable is not being changed or removed as it is required for successful test discovery and execution.TEST_RUN_PIPE = 

Steps to reproduce:

1. Connect to remote docker container over ssh / tunnel
2. Configure test settings, in this case unittest
3. Test Discovery reports error. But tests discover, using django and unittest
4. Run tests with converage. Tests succeed but then trigger failure as coverage can't be evaluated due to connection failure for TEST_RUN_PIPE =(or so it appears)

Hi! This is a known error we are having where there is an issue sending a message even when everything else works right. We are fixing this as part of #23279. If the error is all you are seeing (and not any behavior issue with the extension) then I can follow back up when make the change- thanks!!

[msmitherdc]

Well I was trying the test the new coverage output from tests and as far as I can tell this was the reason that coverage could not be communicated. If this is not a real error, I will have to look more.

[eleanorjboyd]

Are you on the most recent version of the python pre-release? Could you check to see if you get Coverage data received. in your python output logs? You will need to set your log level to verbose which you can do by calling the command from the command palette "developer set log level" and rerunning the coverage request. Thanks

[msmitherdc]

Looks like this is being tracked here #24199

I am on the latest python prerelease and insiders. But I do not get the coverage data received. But seems like this is more an issue with the Django testing so I can close this here
