Expected behaviour

Expect that breakpoint set in script called by test to work with no errors, since it works fine outside of debug mode.

Actual behaviour

I get an ImportError when the package is clearly present within my conda environment.

Steps to reproduce:

I have two files example1.py and test_example1.py. I also have the necessary extensions for debugging python and use of pytest installed. I’m, using version 1.48.2 of VSCode.

example1.py contains a simple import:

import pandas as pd

test_example1.py contains a dummy test which imports example1 as a module:

import pytest

def test_example_1():
    import example1
    assert True

Above line 3 of test_example1.py I see a couple of options appear, namely “Run Test” and “Debug Test”:

Clicking on “Run Test” I get no errors in the “OUTPUT” window:

============================= test session starts =============================

test_example1.py .                                                       [100%]

- generated xml file: C:\Users\aboufira\AppData\Local\Temp\tmp-24288qcdiq9isFmog.xml -
============================== 1 passed in 0.67s ==============================

However, if I place a breakpoint on line 5 in test_example_1.py and click on “Debug Test” I get an error:

Exception has occurred: ImportError
Missing required dependencies ['numpy']
  File "D:\project\example1.py", line 1, in <module>
    import pandas as pd
  File "D:\project\test_example1.py", line 4, in test_example_1
    import example1

Doing a conda list numpy in my current environment in the terminal window reveals that conda is available, so I don’t understand why this error occurs.

Hey, the last comment was solved when I commented a line in the testing configuration in setup.cfg

[aliases]
test=pytest

# [tool:pytest]
# addopts = --verbose --junit-xml=report.xml --cov --cov-report=xml:coverage.xml --log-cli-level=10

The --cov is the one generating this behavior.
