Testing coverage is also testing for Python virtual environment #25661
Description
Type: Bug
The Test Explorer page is also looking for Python files inside virtual environment directory when using Run Tests with Coverage.
- Create a Python virtual environment
- Install
pytestandpytest-cov - Create some tests
- Run tests with coverage
The only workaround I found was to use the --cov option in pytestArgs on settings.json:
"python.testing.pytestArgs": [
"tests",
"-vv",
"--cov",
"--cov-report=xml",
],The "--ignore=.venv/" flag in pytestArgs is (ironically) ignored and it doesn't make a difference.

hm I do not get the same behavior- here is my folder that I was testing with. Can you try this and see?

Also here we append the
--covarg and set it to the root dir so you shouldn't need to include the arg unless you want to override the existing behavior we have: https://github.com/eleanorjboyd/vscode-python/blob/5f33bcee29f329e1d8d05f461e4a2665c36c3d65/python_files/vscode_pytest/run_pytest_script.py#L38senese commentedon Dec 19, 2025
Hi Eleanor Boyd (@eleanorjboyd). I ran your tests here, it didn't read the virtual env. I installed my dependencies and also tried with the
pytestArgsthat I was using and still nothing. So I suspected that the problem was in my workspace and found the problem.Some time ago I updated the Python version of the project and didn't realized that I had two virtual environments
.venvandvenvdirectories. Onlyvenvwas active, so that is why.venvwas being "tested".I'm sorry about this mistake. You can close the issue.

glad it got figured out! No worries and happy coding!
