Pytest Discovery Error

[alimbada]

Type: Bug

Behaviour

Expected vs. Actual

Expected: Discover, run and debug tests
Actual: Python3 error (see output from Output panel below).

Steps to reproduce:

1. Try to discover/run/debug tests

Everything works fine from the terminal using the same command (python -m pytest --collect-only tests) from the same cwd (./backend/). Tests also run fine using pytest, pytest -v, python -m pytest and python -m pytest tests

The project structure is as follows:

<PROJECT_ROOT>
  |-backend
  |  |-.pytest_cache
  |  |-tests
  |  |-models
  |  |-__pycache__
  |  |-venv
  |  |-data
  |  |-services
  |-frontend
  |-.git
  |-.vscode

The diagnostic data below shows virtual environment as Global despite the fact that I am using a virtual environment. I have since changed the value of python.defaultInterpreterPath to backend/venv/bin/python and the virtual environment is now being detected and I have changed the interpreter path to use it. However, this has made no difference to test discovery.

Additionally, I'd like to add that as a workaround I have installed the Python Test Explorer extension by the Little Fox Team as this at least allows me to debug tests which is the whole reason for me wanting to run tests from VS Code. I can debug tests using the inline buttons that the aforementioned extension shows in the editor. The test explorer itself is still broken.

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.11.4
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Global
• Value of the python.languageServer setting: Default

[eleanorjboyd]

Thank you for your issue report. We are looking into this now! In the meantime, you are likely on the new testing rewrite and this is why you saw a change in behavior. You can opt out of the rewrite as I get this fix in by setting this in your user settings: "python.experiments.optOutFrom": ["pythonTestAdapter"],. If this doesn't work let me know as this will mean it is a different issue. Thank you and I will send updates in this thread as I get a fix in.

[alimbada]

Hi @eleanorjboyd,

Thanks for your reply. I've actually just got test discovery and debugging working now by changing python.testing.cwd to ${workspaceFolder}/backend instead of just backend. I thought I'd tried this before but maybe the combination of setting python.defaultInterpreterPath to backend/venv/bin/python along with setting python.testing.cwd fixed it. Previously, I was unsure if the ${workspaceFolder} placeholder would work as it did not show up as an autocomplete option when changing that setting but a suggestion from a StackOverflow comment prompted me to try again and this time it worked.

There is one outstanding issue which is that running tests without debugging shows 0/0 tests passed 0.00% in the Test Explorer and shows the following in the output (with one client connection line per test):

2023-08-04 17:20:56.782 [info] > ./backend/venv/bin/python ~/.vscode/extensions/ms-python.python-2023.14.0/pythonFiles/vscode_pytest/run_pytest_script.py --rootdir .
2023-08-04 17:20:56.782 [info] cwd: ./backend

2023-08-04 17:20:57.996 [info] Client disconnected

As mentioned in my previous post, I only need to run tests in VS Code to debug so I'm happy with the current situation as I can still run tests from the terminal and have set up a VS Code task to do so.

However, in the interest of providing more data to improve this extension I applied your suggestion of setting python.experiments.optOutFrom but this did not change the behaviour of running without debugging.

[eleanorjboyd]

Thanks for the extra info! From your perspective what is the desired experience on the python.testing.cwd? Did you find that confusing that it required you to provide the workspace folder? Just curious about your thoughts.

Yes, the test server connected to a client does print every time- I will work on a fix.

Finally the issue regarding 0/0 tests passing is interesting. What type of tests are you running? Like normal pytests or any unittests / subtests? If you could maybe provide the output from your test run from the "python test logs" this might help me determine why the display isn't right. Thanks

[JackMorganNZ]

I would like to add I've been having a similar issue reported here for the past few weeks. Thank you @alimbada for finding a workaround. Installing the Little Fox Team extensions worked without changing any of the VS Code settings.

@eleanorjboyd Reverting to the previous test adapter allows tests to discovered and run correctly within the test explorer (both sidebar and inline), but switching to the new test adapter results in the "0/0 tests passed" issue mentioned by @alimbada. I am running pytest with a Django project, with a few extensions installed.

The 'OUTPUT' tab for Python shows (includes redacted lines, happy to send these privately):

The 'TEST RESULTS' tab shows:

Happy to provide do more tests or provide more information, let me know what you need. I've reverted by to the original test adapter for the moment.

[alimbada]

Thanks for the extra info! From your perspective what is the desired experience on the python.testing.cwd? Did you find that confusing that it required you to provide the workspace folder? Just curious about your thoughts.

@eleanorjboyd, yes, I wasn't sure if ${workspaceFolder} needed to be part of the cwd as usually the autocomplete suggests the placeholder variable but in this case it did not.

Yes, the test server connected to a client does print every time- I will work on a fix.

Finally the issue regarding 0/0 tests passing is interesting. What type of tests are you running? Like normal pytests or any unittests / subtests? If you could maybe provide the output from your test run from the "python test logs" this might help me determine why the display isn't right. Thanks

I am running normal pytests. The Python Test Log output is below. It is the same output as what I get when running tests in the terminal.

I also was hit with the "no tests discovered" issue.

Running pytest mymodule in terminal finds and executes tests as expected.

But when configuring tests via VScode palette command "Python: Configure tests"

• -> select test framework: pytest
• -> select the directory containing tests: mymodule

Now testing view shows mymodule, but lists 0/0 tests. Pressing the run button does something ("Finished running tests!") but no test cases are actually run.

Copying the .../run_adapter.py discover ...from Python log and running it manually produces JSON output that does mention the test files and cases. So it seems the underlying test discovery mechanism works but the information then just doesn't reach the UI.

Anways, adjusting the auto-configured setting
"python.testing.pyTestArgs": "mymodule"
with
"python.testing.pyTestArgs": "${workspaceFolder}/mymodule"

seems to work around the problem for me. Tests are now discovered and run as expected.

[eleanorjboyd]

Hi @MawKKe! It seems that your issue may be different- could you open a new issue and we can converse there? Also can you also see if there is a difference if you are on our new rewrite? You can make sure you are on it by adding this setting to your user settings.json "python.experiments.optInto": ["pythonTestAdapter"].

You can confirm you have the rewrite enabled by setting "python.analysis.logLevel": "Trace", in your user settings then check for Experiment 'pythonTestAdapter' is active in your python logs.

Thanks!

[eleanorjboyd]

Hi @JackMorganNZ sorry for the delay in responding!

Could you send your settings for python.testing.pytestargs and an example of the test files you are running? If you can't share the exact tests you are running a minimal repro or a description of what these tests look like would be great.

Also to clarify discovery is working fine but run is not working at all? When you say "0/0 tests passed" no tests data is being returned at all right?

Thank you for your assistance I appreciate any help you can provide!

[pnelson-bto]

I am getting this in my Python Test Output. This was working as expected until yesterday when it seems that VSCode may have updated.

[eleanorjboyd]

hm very interesting. That block of code is already in a try-catch to handle any key errors but that didn't catch it because it was a different error type. Can you send along if you are using any plugins? Also can you send the machine you are using / any interesting setup there? Thinking it tried to throw a key error but instead threw an internal error because of the system. Thanks

[pnelson-bto]

I'm on Ubuntu. The other test explorer seems to work fine, but the one by Little Fox Team does not. I prefer that one because of the tree view.

[eleanorjboyd]

What do you mean by the other test explorer?

[pnelson-bto]

There are 2 test extensions installed:

• Python Test Explorer for Visual Studio Code by Little Fox Team
• Test Explorer UI by Holger Benl

If I switch Python extension to pre-release version, the internal error goes away. However, the gutter decorations disappear.
Both v2023.16.0 and v2023.18.0 have the same issue.

If I switch Python extension to v2023.14.0, everything works as expected.

I believe @JackMorganNZ and I are having the same issue.

[tboddyspargo]

I started hitting an problem yesterday/today that seems similar to comments on this issue. I'm using a workspace configuration where python.testing.pytestArgs is defined in the code-workspace file and each folder inherits from it.

"python.testing.pytestArgs": [
      "--disable-warnings",
      "-vv", // Shows full diff on test failure
      "-s", // Shows print statements in test output
    ],

However, I've also tried removing all those args and my experience doesn't really improve.

I see a lot of this in the Python logs:

2023-10-11 10:25:19.336 [error] pytest test discovery error 
  
 The python test process was terminated before it could exit on its own, the process errored with: Code: 4, Signal: null

Followed by:

Disposing data receiver for /Users/me/workspace/folder and deleting UUID; pytest discovery.

The "Python Test Logs" can barely render because there's so much content and it gets cleared/overwritten so quickly, yet what I do see seems to be "status": "success" messages that are listing all the discovered tests, followed by:

Plugin error connection error[vscode-pytest]
[vscode-pytest] data: Content-Length: 13537
Content-Type: application/json
Request-uuid: None

NOTE: On VSCode startup, it actually seems like multiple discovery runs are successful before some failure triggers the removal of all preceding results...

My Test Explorer panel seems to be "hiding" (the result of the deleting UUID lines, no doubt) the tests that I expect to be discovered.

I can see nothing wrong with my pytestArgs that would cause the 4 exit code...

[eleanorjboyd]

Hi, thanks for including this info. When an error occurs when we try and send the data it prints it all out which is why you are seeing so much data and it also retries which causes it to write over the data printed first.

What is your setup for your machine? Are you using SSH or anything to connect to a remote machine and what are the machine types?

[tboddyspargo]

Thanks for your response, @eleanorjboyd!

What is your setup for your machine? Are you using SSH or anything to connect to a remote machine and what are the machine types?

I am not using SSH for anything. Remote machines are not involved. I'm running on a MacOS 14 Apple Silicon machine using the arm64 build of VSCode. Are there any other machine details that would be helpful?

Perhaps also relevant: In my setup, each workspace folder that runs pytest is relying on a relative .vscode/settings.json file that defines its python.defaultInterpreterPath as .venv/bin/python (meaning, each workspace folder has its own local virtual environment that should be used for running test discovery). From my brief interpretation of the logs, I believe this is happening as expected.

2023-10-11 12:36:10.174 [info] > ~/workspace/folder/.venv/bin/python -m pytest -p vscode_pytest --collect-only --disable-warnings -vv -s
2023-10-11 12:36:10.174 [info] cwd: ~/workspace/folder

---

One other note: I have known, but wasn't previously concerned about, missing packages in some of my workspace folder virtual environments. As a test, I started installing those missing dependencies and more and more test discovery results seemed to populate the Test Explorer.

This, again, makes me suspicious that there's some unintended interdependence between spawned process results for multiple workspace folders. I would expect the outcome of test discovery for one workspace folder to never affect the outcome of another. Yet the pattern of test enumeration, then disappearance accompanied with the observation that the results improve as exceptions are addressed is rather suggestive.

[eleanorjboyd]

seems to be similar to: #22192 (comment). The UUID is shown as not defined which means the port would likely not be defined either. What version of the python extension are you on @tboddyspargo?

[eleanorjboyd]

@pnelson-bto, our team only supports the core functionality of the Python extension and not any other extensions that you can install such as Little Fox Team. If you are seeing any issues with the default text explorer then I can help you there otherwise I would reach out to the Little Fox Team specifically as they can help with issues on their extension. Thanks!

[tboddyspargo]

What version of the python extension are you on @tboddyspargo?

I'm on ms-python.python version v2023.18.0

One other note: I have known, but wasn't previously concerned about, missing packages in some of my workspace folder virtual environments. As a test, I started installing those missing dependencies and more and more test discovery results seemed to populate the Test Explorer.

Further experimentation down this path resulted in me resolving all test discovery issues (e.g. exceptions for missing imports, non-zero exit codes for no tests discovered, etc.) in all workspace folders. That results in all tests enumerating and populating the Test Explorer page as expected without disappearing. Again, a big contributor to the impact of the problem seems to be: discovery errors in workspace folderB clearing the successfully enumerated tests from workspace folderA.

[eleanorjboyd]

hm yes- I am seeing how this would happen. It is written that the test explorer is cleared when the Python subprocess exists with a non-0 exit code which happens when this other issue arises. Will put in a fix for this

[eleanorjboyd]

Hello! You're experiencing an issue with the pytest hooks coming from our extension implementation. Do you have any other plugins you are using? They might be conflicting with each other. Otherwise I think #22240 will fix it. Once that is merged if you could try it with the newest version of the python extension tomorrow that would be extremely helpful! Thanks

[msonsona]

Thanks for the super-quick fix, will definitely try it out!

[MaxHorwood]

I was having this issue. Switching to pre-release fixed this for me. However, when the tests run I no longer get the green "tick" despite my tests all passing. Red circle shows as normal when test fails.

[msonsona]

mmm I can't seem to get it working yet despite using the pre-release version (currently using v2023.19.12901009)

[eleanorjboyd]

@MaxHorwood can you send over your logs and a description of your workspace?

[eleanorjboyd]

@msonsona can you send over a minimal repro of what is failing? I might not have gotten your configuration right and therefore not fixed the root cause. Also do you have any plugins in use for pytest and is the error your experiencing now still the same? Sorry for all the questions!

[msonsona]

not sure how to check the plugins for pytest, but if I run the test discovery command directly from the command line without any additional argument, it runs properly

the issue I see in my environment, is that VS Code is trying to discover the tests using the vscode_pytest plugin:

2023-10-18 18:02:41.987 [info] > . ./env/bin/activate && echo 'e8b39361-0157-4923-80e1-22d70d46dee6' && python ~/.vscode/extensions/ms-python.python-2023.19.12901009/pythonFiles/printEnvVariables.py

but it's not present in my environment:

During handling of the above exception, another exception occurred:

ImportError: Error importing plugin "vscode_pytest": No module named 'vscode_pytest'

if I try to pip install it won't work, so not sure if that flag can be disabled and run the test discovery without it?

[tboddyspargo]

I don't want to distract from any of the other repros, but I did just identify a case where we had a pytest hook that was running os.environ.clear() (even during discovery, apparently). This was a bad practice (and we've removed it), but it did result in VSCode discovery failure (until it was removed). Presumably this is because discovery success/completion depends on specific environment variables (e.g. TEST_UUID, TEST_PORT, etc.) being present even after tests run.

[eleanorjboyd]

the plugin vscode_pytest is a custom plugin we wrote to collect all discovery / run results and return them to our extension via a socket. This is required for the implementation of our new rewrite. The plugin is located inside the extension we bundle and add the location to the python path before run which is why we can find the plugin when we run it and you cannot when you run it locally. You can add the path to PYTHONPATH before running from the command line then it should work. The path to add is: the root of your extension + pythonFiles. There you will see a folder called vscode_pytest which is the plugin we created which python will now be able to find.

With this being said it seems like there is not a problem with your configuration (since it works normally from the command line). The next step is for me to try and repro your behavior or understand what your workspace looks like. What version of pytest are you using and are you able to make a minimal repro to send my way?

This error is in the hook implementation I have for our plugin and it not aligning with what pytest expects so I am trying to figure out where that mismatch could have occurred in your configuration. Thanks!

[msonsona]

are you able to make a minimal repro to send my way?

sorry for the ignorance, what would be the best way to provide this?

I might be using a quite old version of pytest, to be honest, this is what I get inquiring the version:

[MaxHorwood]

@MaxHorwood can you send over your logs and a description of your workspace?

@eleanorjboyd The logs don't show much. Just as I'd expect, example below is just one test but is the same as running all.
Workspace is a docker-compose which spins up a database, runs some migrations etc. Tests connect to that. There are >500 could it just be quantity?
I have another separate project/workspace which all works as expected.
(These may be the wrong logs happy to give any others)

@msonsona, could you try running pip install --upgrade pytest then running again? We are on pytest 7.4.2 now so I am not sure if there has been changes to this specific hook but that could be an issue.

In terms of a minimal repro this is just a small example project that replicates the bug. If you are happy to share your current project you could send that over so I can try it myself but since some people do not like sharing their whole projects a minimal repro could be a small project you create where you still see the bugs. For example if you create a new workspace, create a simple pytest, and run it does the bug still exist? If so then send over that simple pytest so we are talking about running the same code. Thanks!

@MaxHorwood we have done many size tests (with repos >20,000 tests) to try and test against any size issues so hopefully that's not the issue. It seems like your pytest works right and doesn't error so it might be on the vscode parsing side. Can you send the "python" output logs? This will show what is happening once vscode receives the data and why you would "no longer get the green "tick" despite my tests all passing". Specifically there will be something printing a payload and i am curious for the tests you expect to be successful what that says

[eleanorjboyd]

hm this is not what I expected to see. I have just added some extra logging which will be on the pre-release of the extension tomorrow. Would you be able to try it again tomorrow and send the same logs? You should see more logs regarding data received.

[MaxHorwood]

Sorry for the delay, this is now working as expected... I don't believe I've changed anything on my end, maybe it was sleeping the computer (which I do regularly and not shutdown - but I did also have to reload vscode when switching to the pre-release anyway so that's a bit odd)
Version: v2023.19.12980103

Switching back to release version is still broken.

[msonsona]

@msonsona, could you try running pip install --upgrade pytest then running again? We are on pytest 7.4.2 now so I am not sure if there has been changes to this specific hook but that could be an issue.

After upgrading pytest to 7.4.3 (it's a work-related repo, so not 100% sure about the feasibility of upgrading this on my end, but let's try for now), I also upgraded to the pre-release version of the extension (now running v2023.19.12981006), and had to remove the folder argument for pytest being set originally in my .vscode/settings.json:

{
    // "python.testing.pytestArgs": [
    //     "repo_test"
    // ],
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true,
    "python.testing.pytestPath": "/Users/me/code/repo/env/bin/pytest",
    "git.closeDiffOnOperation": true,
    "python.testing.cwd": "/Users/me/code/repo/repo_test",
    "python.analysis.typeCheckingMode": "off",
    "python.analysis.autoImportCompletions": true
}

and now it seems to be able to discover and run tests!

thanks @eleanorjboyd for your support! 🙌

[eleanorjboyd]

Hi @MaxHorwood, glad it now works! That's weird it happened unexpectedly but let me know if it resurfaces.

@msonsona glad that upgrade worked as well! Are you not sure about the feasibility at your company you are saying as opposed to just on your own machine? Let me know if you do have any other questions, I am closing this as resolved in the meantime. Thanks!
