vscode-python: 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:
