PATH for selected Venv not used when pytest test run via Run Test

[andrewstevens-infineon]

Type: Bug

Behaviour

When a pytest test is launched using the "Run Test" Button/Command the environment of the selected virtualenv appears not to be set. This contrasts with the behaviour when "Debug Test" Button/Command is used where the Venv environment is used. This will (for example) break test suites relying on finding executables installed in the virtualenv bin directory on PATH.

Steps to reproduce:

1. Create small pytest test suite.
2. print(os.environ) in test.

import os

def test_environ():
    print("PATH", os.environ["PATH"])

See attached output captured from run.

Run_test_run_output.log

Hi I think this is a duplicate of #23408, please let me know if not and I can reopen- thanks!

[andrewstevens-infineon]

It doesn't seem to cover the aspect that inconsistent launch environments between Run test and Debug test (definately not right). I'll add a comment in #23408.
