Type: Bug

Behaviour

Expected vs. Actual

Expect the extension to discover pytest test functions. Instead, it reports an "unexpected situation".

Steps to reproduce:

  1. Enable pytest testing.
  2. Point test discovery at a specific test module by specifying a relative path with "python.testing.pytestArgs": ["test/unit/test_baseline.py"].
  3. Run "Refresh Tests" command.

Diagnostic data

  • Python version (& distribution if applicable, e.g. Anaconda): 3.9.6
  • Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Venv
  • Value of the python.languageServer setting: Default
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Sanitized Python extension output:

    The code is not public. Here's a sanitized version of test_baseline.py:

    from utils import DATA
from fireball.io.trace import TraceReader
import fireball.baseliner as baseline
import matplotlib.pyplot as plt
import numpy as np


def test_baseline_trace(do_plots=False):
    """
    Test baseline estimation.

    Args:
        do_plots: Set to true to bring up some matplotlib plots.
            Note these do not get written to disk - these are for
            viewing in PyCharm (IMHO). If you leave this true after grokking the plots,
            it is conceivable that this test might do ... something odd when run from
            the command line, although it typically will not.
    """
    
    # private code eliminated

    if do_plots:
        # plot the extracted baseline mean and sigma
        plt.figure()
        x = range(0, 2000)
        plt.plot(trace[x], 'b', zorder=1)
        plt.plot(baseline_est.mean[x], 'r', zorder=2)
        upper = baseline_est.mean + baseline_est.sigma
        lower = baseline_est.mean - baseline_est.sigma
        plt.fill_between(x, lower[x], upper[x], alpha=0.5, zorder=3, facecolor='LightGreen')
        plt.xlabel('frame (' + str(test_trc_name) + ')')
        plt.ylabel('DN')
        plt.title('baseline estimation')
        plt.show()

    I'm not sure what you mean by "test settings". Here are the python.testing things in my settings.json:

    {
    "python.testing.pytestArgs": [
        // "--no-cov",
        "test/unit/test_baseline.py"
    ],
    "python.testing.unittestEnabled": false,
    "python.testing.pytestEnabled": true,
}

    I just noticed the extraneous , in this JSON, but removing it doesn't appear to have any impact.

    Hello, this looks to be a bug in the test adapter and is likely related to the ongoing buggy behavior on pytest discovery and running in vscode. We are currently work on a rewrite of how pytest works in vscode and hope this rewrite will fix this and similar bugs. The main issue which will be working on is here: #17242, and progress will be updated on this issue. Thank you!

    Are there any known workarounds, I've been wanting to use this feature since it came out but its never been able to discover the tests.

    Peter LaFosse (@plafosse), could you provide more information on your situation specifically? Since it is a general error code I am not sure any workarounds unless I see what more specifically you are running into. Settings and logs would be helpful to diagnose- thanks!

    Hello! We have just finished our testing rewrite and are beginning the roll out to users. I have tested this issue with the re-write and I am no longer reproducing the bug! If you would like to try it yourself, you need to be on vscode insiders and then add this setting to your users settings.json "python.experiments.optInto": ["pythonTestAdapter"]. We are in the process of switching all users to the rewrite but are doing so incrementally so if you do not have insiders, watch our release notes to get updated on when it will begin to hit stable. Let me know if it doesn’t work for you and we can re-open this issue. Thanks!

    verification steps same as repro steps:

    1. Enable pytest testing by adding this to your settings: "python.experiments.optInto": ["pythonTestAdapter"],
    2. Point test discovery at a specific test module by specifying a relative path with "python.testing.pytestArgs": ["test/unit/test_baseline.py"].
    3. Run "Refresh Tests" command & make sure it locates the test correctly

    example for what could be in your test file:

    def test_this():
    assert True

    The Refresh Tests command does nothing for me. I added the setting to my User settings file. Am I supposed to press the Configure Python Tests button first? There's also a single info log that shows up saying that it's discovering tests, but no trace or debug logs seem to appear after.

    macOS
    Python extension v2023.11.11791005

    Edit: I just noticed I didn't enable the pytestEnabled setting. Will see if that fixes it.

    The extension discovered the test in test/unit/test_easy.py now, but I got stuck a few times.

    1. I forgot to set python.testing.pytestEnabled to true.
    2. I knew I needed to create an environment (because I made a new repository), but then I forgot to install pytest into it.
    3. After installing pytest, the extension discovered the test.

    I'm guessing the usual flow is to press the "Configure Python Tests" button, still? I feel like I took a much more manual approach this time.

    Hi! Sorry for the ongoing confusion. Yes, it will work best to do Configure Python Tests as this will set the python.testing.pytestEnabled to true. The current flow we think for our users is they have a repo with tests or just wrote them, they click on the test explorer icon, follow the prompts to setup their testing with Configure Python Tests then discovery should work. By the time they get to the test explorer we expect them to already have pytest installed since they will be using it in their workspace already or have it listed as a dependency. Hope this clarification helps and let me know what is still confusing you as I am thinking about how to update this flow in the future and would love any input. Thanks!
