Test Discovery Failing in all repos (for the Testing Panel)

[sarahandromeda]

Type: Bug

Behaviour

When trying to use the VSCode Testing from the sidepanel, Tests are not Discoverable due to a permissions error.

I first noticed this in a single repo I was working in. I opened up another repo to see if the error persisted and it did. Then I created a separate directory with a very simple example to test and the error still occurred there as well.

Example file structure:

├── app
│   ├── __init__.py
│   └── sum_nums.py
└── tests
    ├── __init__.py
    └── test_sum_nums.py

As far as I know, nothing has changed in my system, no major updates or upgrades have happened before or since this started happening. Perhaps a chmod is needed but I am hesitant to do that without knowing why.

Why is this only occuring now? Has there been a change to the files used for the Testing execution in the last few days/weeks?

I was able to restart my computer this morning, open up a repo and run 1 test via the VSCode Testing but it only allowed me to run the singlular test before showing the error again.
I aslo recreated my Virtual Enviroment but that did not work either.

Steps to reproduce:

• Open any repo with Python code and associated tests
• Select the Testing tab in the side panel
• In side-bar, message appears Unittest Discovery Error
• Open Up the Outputs tab to Python
• See Discovery Error due to file lacking permissions (Please See Output Details Below For Outputted Error)

Tests CAN be run successfully from the command line: python -m unittest discover

Diagnostic data

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

I have the same problem with discovering pytests. When I switch to v2024.4.1 the test discovery succeeds.

This started happening to me after VS Code updated today.

[eleanorjboyd]

Hi! We have not made a change to unittest recently- is everyone seeing this on unittest or with pytest too? Could someone try just running unittest/pytest from the command line and seeing if they see similar permissions issues?

[sarahandromeda]

Could someone try just running unittest/pytest from the command line and seeing if they see similar permissions issues?

I only use unittest so I can't speak for pytest. However, I can run unittest from the command line with no issues. I can even run the debugger on unittest files. It is just the test discovery that is failing and leading to not being able to use the testing side panel to run anything.

[eleanorjboyd]

Interesting, it seems that your error /run/user/1000/python-test-discovery-a121c3ca49a094028295.sock is referencing our use of named pipes for communication. This is the same type of communication that run and debug use- could you check for a a similar name for the pipe in your logs for run? Secondly do you have any settings which might restrict thing? See here as we have just changed to named pipes but we do know a few issues still exist: #23279. Thanks

Today, after I restarted my computer, the Testing tab opened the test configuration dialog. I selected pytest and the configuration file, and the tests appeared. This is what I see in the Python Output tab:

There are some errors about test discovery being already in progress, and finally the permission denied error. Anyway, I can attempt running a test, but the test won't run. In Python Output tab I can see the same permission denied error for test execution:

2024-05-22 07:24:07.365 [error] pytest test execution error
 [Error: listen EACCES: permission denied /run/user/1000/python-test-results-7f1a0877cc739fa109ec.sock

My code is in WSL and I'm using pytest. I can run the tests from WSL command line using python -m pytest tests.

[philipphofmann]

I can collect the tests without problems from the command line python -m pytest --collect-only tests. It's worth noting that I use a custom venv as you can see from the logs.

@karthiknadig any thoughts here on what could be causing people to suddenly have permissions issues?

[karthiknadig]

@eleanorjboyd This is the issue with using Unix Domian Socket for communication:

permission denied /run/user/1000/python-test-discovery-a121c3ca49a094028295.sock

We are working on a fix for this to use fifo pipes, than UDS pipes. For work around, see if you can allow Unix domain sockets temporarily until we get the fix out. Or, another option is to pin the extension to the older one where this works.

Interesting, it seems that your error /run/user/1000/python-test-discovery-a121c3ca49a094028295.sock is referencing our use of named pipes for communication. This is the same type of communication that run and debug use- could you check for a a similar name for the pipe in your logs for run? Secondly do you have any settings which might restrict thing? See here as we have just changed to named pipes but we do know a few issues still exist: #23279. Thanks

Sorry for the delay on this.

your logs for run

Do you mean in the output tab when running the tests with the debugger? (SEE BELOW)

When running the debugger on a unittest file, this is what gets logged to Output: Python

2024-05-22 15:17:54.658 [info] Send text to terminal:  /usr/bin/env /home/sgomez/my_project/.venv/bin/python /home/sgomez/.vscode-server/extensions/ms-python.debugpy-2024.6.0/bundled/libs/debugpy/adapter/../../debugpy/launcher 56803 -- /home/sgomez/my_project/tests/test_logging_helper.py 

And this it what appears in Output: Python Debugger:

2024-05-22 12:36:22.898 [info] Name: Python Debugger
2024-05-22 12:36:22.898 [info] Module: debugpy
2024-05-22 15:17:52.994 [info] DAP Server launched with command: /home/sgomez/my_project/.venv/bin/python /home/sgomez/.vscode-server/extensions/ms-python.debugpy-2024.6.0/bundled/libs/debugpy/adapter

Neither seem to reference the same pipe.

Secondly do you have any settings which might restrict thing

I don't believe so, I have not updated any settings recently. However I am using WSL on a Windows machine, but again, I have not changed any settings in my WSL or on Windows (other than system updates).

[senarvi]

It started working when I installed the version 2024.4.1 of the Python extension. @karthiknadig are you thinking about enabling Unix domain sockets in Windows or in the WSL distribution? Any idea how to do that?

[karthiknadig]

@senarvi we are working on using fifo instead of UDS. The issue is with WSL2 where UDS not supported. It is supported in WSL1 though.

[Code-ScottLe]

Also, for this bug, is it expected to see the "Testing" window showing like this? Despite running "Configure Python Test" multiple times

Having the "Build your C# test project" is a bit weird.

I also have been seeing VS Code attempts to use pytest even though i'm explicitly using unittest in the configuration.
