Actual behavior

Tests are discovered and run in Python-3.6 conda env, but not in Python-3.7, which doesn’t discover tests and/or fails in conftests.py when importing numpy, fails to load DLL multiarray. But numpy does work in a terminal, when py37 is activated, and I can import multiarray from numpy.core.

Also I can even run pytest directly from the terminal inside vscode, so it’s something specific to how the tests are implemented. Maybe it’s not implementing the conda environment correctly?

Same issue with both pytest and nosetests.

Expected behavior

discover and run tests in Python-3.7 same as in Python-3.6

Steps to reproduce:

1. install anaconda
2. create py3.6 and py3.7 environments
3. install vscode, python extension
4. open a python project with testing (that uses numpy?), enable testing, select each environment and run tests.

Just so people know, we’re trying to schedule a meeting with Anaconda to figure out how best to handle this. Once we have that meeting we will be in a better place to know how to solve this going forward.

[gvellut]

I had the same issue. Until it is fixed, I created a batch file :

@echo off
C:\\Users\\gvellut\\Anaconda3\\Scripts\\activate.bat wbt2 && pytest %*

And configured the “python.unitTest.pyTestPath” option to launch it (instead of pytest directly).
