Error: Got unexpected extra arguments (lib platformio.ini src)

Hi,

when using the default PlatformIO project for ESP32 (I don’t think this is related to the board) in VSCode, I cannot run unit tests via the big testing icon on the left sidebar.

Executing a test delivers:

Error: Usage: python -m platformio test [OPTIONS]
Try 'python -m platformio test -h' for help.

Error: Got unexpected extra arguments (lib platformio.ini src)

When running it via the testing icon on the bottom it works as expected (since the default project has no tests defined):

Executing task in folder test_project: C:\Users\User Name\.platformio\penv\Scripts\platformio.exe test 

Verbosity level can be increased via `-v, -vv, or -vvv` option

Is there a way to configure the VSCode native testing button to work with PlatformIO?
