Error running test with pytest

Issue Type: Bug

I have a simple test scenario which yields some errors in vs code. I'm trying to run the following little program with the Python extension:

import os
import shutil


def test_something():
    assert True == False


def setup_module(module):
    """ setup any state specific to the execution of the given module."""
    os.mkdir(".tmp")
    os.chdir(".tmp")


def teardown_module(module):
    """ teardown any state that was previously setup with a setup_module
    method.
    """
    os.chdir("../")
    shutil.rmtree(".tmp")

I get the following two errors:

cannot open file:///home/erikah/ok/plattform/test/test_something.py. Detail: File not found (file:///home/erikah/ok/plattform/test/test_something.py)

This path seems to be wrong, given that the path to the program is /home/erikah/ok/plattform/python_testing/test

There was an error in running the tests.
Running the test in the command line I get the following:

Btw., running python 3.6.7.
Another example, also failing:

import os
import shutil

import pytest

@pytest.fixture
def clean_dir():
    os.mkdir(".tmp")
    os.chdir(".tmp")
    yield
    os.chdir("../")
    shutil.rmtree(".tmp")


def test_something(clean_dir):
    assert True == False

Seems like I get the following when I use the command "run all unit tests".

Error: Error: Illegal value for line
I've tried disabling all extensions except for Python.

I'm still experiencing this.

When using fixtures, where I run tests with temporary directories for instance, this happens.

/home/erikah/ok/plattform/k8s-namespaces/k8s-namespaces/test_k8s_installer_namespace.py.
                                         ^^^^^^^^^^^^^^

I just ran into the same or a similar issue. Running the tests again via the tests button in the bottom status bar seems to (at least temporarily) have solved the problem.

I'm getting the same error despite passing tests:

We are going through old issues and we noticed that no one from the team had replied to this issue. I want to apologize for the oversight and to let you know that the issue was reviewed by the team and triaged (as shown by the labels applied to this issue).

is this issue related to #12403 by any chance?

Almenon (@Almenon) I believe they are different issues.

Still experiencing in vscode:

Fixed by Re-Discovering the tests

Same issue :

Python 3.7.7 (conda)
VS Code 1.51.1

I believe it was caused by a test previously discovered, then commented and that was trying to be run through "Run all tests" button.
As stated in the above comment, re-descovering the tests fixed the problem.
A message a little more explicit that "Illegal value for line" would be appreciated though

I'm getting this now I think, and no matter what I do I can't get it working.

In VS code I configure "Cwd" as "src", since that's where the source code for my Django project is. root dir contains all the config files, docker stuff etc.

With "src" in place, test explorer shows the tests, but they can't run. Without it, nothing is found.

If I run the tests with "src" set as cwd, I get an error telling me it couldn't find project/path/src/src/rest/of/tests/test_model.py - i.e.. the src has been applied twice somehow.

I've removed .pytest_cache, restarted VSC, rediscovered things, in every possible order, but can't get rid of this.

At the moment, I'm resorting to running my tests manually outside of VS Code. Any news on this issue?

Just encountered the same issue. Simple test passes from Terminal, but fails with this error in VSCode. Running "Rediscover all tests" fixes it.

I ran into the same error. The path it was searching for was wrong.
What happened was that my pycache files were originally in another directory (due to docker mounts). Removing the all the pycaches resolved the issue: find ./ -name "__pycache__" -exec rm -rf {} \+

Hello! I have reviewed this issue and given the architectural changes of the testing rewrite, this issue should no longer exist on the rewrite. Therefore I am going to close this issue but please comment or open a new issue if you are still seeing a problem when you try this yourself!

To use the rewrite yourself just add ”python.experiments.optInto": ["pythonTestAdapter"] to your user settings. You can confirm you have the rewrite enabled by setting your log level to trace, via the Developer: Set Log Level command in the command palette. Then check to see if Experiment 'pythonTestAdapter' is active is in your python logs.

Thanks!
