Can you share your setttings.json for your testing configuration and a code sample that reproduces the problem?

[ShivanshuKantPrasad]

I uploaded the project directory to github.
This is the workspace settings.json file:

{
    "python.unitTest.pyTestEnabled": false,
    "python.unitTest.unittestEnabled": true,
    "python.unitTest.nosetestsEnabled": false,
    "python.unitTest.unittestArgs": [
        "-v",
        "-s",
        "./Tests",
        "-p",
        "*test.py"
    ]
}

This bug seems to happen in Tests/MaximumSubarray_test.py

Can you please verify, @d3r3kk ?

Edit - comment placed in related, but incorrect item!

I cannot reproduce this exact behaviour on Windows nor on Linux. However, I do believe it to be related to #2660 and the registration of our callbacks on unittest projects.

I will continue to attempt to reproduce this behaviour going forward, but I've not yet seen this exact thing.

[brettcannon]

@d3r3kk if you can't reproduce with the provided sample then I'm going to assume that we fixed this.

[d3r3kk]

Just got a repro today - but I am working on related issues that I believe all have the same root cause. Tracking this on #2660, but will reopen this as well to keep things specific.

[d3r3kk]

I can only reproduce this in Windows, and @DonJayamanne didn't see any repro on macOS, so I'm limiting this to a windows-only issue.

@d3r3kk
Surprise surprise, I can't replicate this on Windows with Python 3.5 and 3.7

Interesting! I get it to repro consistently with a venv under python 3.7.

Closing as stale. If you still experience this issue, please file a new one. We refactored a lot of our test related code, so the underlying issue may have changed.
