Running test fails trying to access non-existing file

[tenspd137]

Using vscode-python 2020.6.88468
VSCode 1.46.0

When I run a test using the pytest framework, there is always an error at the end of the log:

Error: Error: cannot open file:///c%3A/Code/pixelcrunch/C. Detail: Unable to read file 'c:\Code\pixelcrunch\C' (Error: Unable to resolve non-existing file 'c:\Code\pixelcrunch\C')

regardless if the test itself actually passes or fails:

I don't know what is causing it to look for this file.

Also, when I try to set a breakpoint and debug the test, I get the following:

I don't know what causes this. Importing pandas at the command line has no problems:

This happens on tests that pass or fail, regardless.

I cant downgrade right now wither, because I currently am affected by issue #99699 -
microsoft/vscode#99699

[tenspd137]

New information - works with python 3.6, not with 3.7 or 3.8

[tenspd137]

Works with python 3.8 if I run conda activate , cd to project folder, and start vscode using "code ." I wonder if it is ignoring some environment setup somehow? This is a workable solution for me, but not ideal. I'll leave it open since it isn't working as expected.

Which log do you see that error message (about file://) in?

The second issue might have something to do with conda environment not getting activated properly. Try activating it manually in an external terminal, and then launching VSCode from said terminal. If that doesn't help, can you please file a separate issue in https://github.com/microsoft/vscode-python/.

[tenspd137]

It shows up in the python test log. It happens after a test fails, and then doesn't seem to go away, even on tests that pass. If I start vscode and run a test that passes, I don't see it, until a test fails. Then it happens after every test.

[tenspd137]

Starting vscode from the directory after starting the environment fixes first problem. Still see file:// problem:

[tenspd137]

Re: Conda environment - I have several - if I select the 3.6 one, there is no problem. It is python 3.7 or 3.8 where the issue arises. Again, starting vscode from terminal works, just not ideal.

[int19h]

We're still trying to figure out automatic conda activation - it's a very complicated problem, unfortunately. You can track that work via #5344.

[int19h]

For the issue with file://, does this only happen when debugging the test, or regardless of how you run it?

[tenspd137]

It happens regardless on the first test that fails, and then the Error does not go away. Tests still report correctly as pass/fail in the panel, but it also shows:

So:
Vscode start
test that passes, no error
test that fails, error
test that passes, error
....

Looks like this is a test runner issue then - I'm going to move it back into the extension repo.
