Hi
I have an issue running pytest commands from the Execute Command node. I’m running the docker container with python and pytest installed. if I run the command “python -m pytest” in the container at /home/node I get a pytest output. If I run that command in Execute Command I get the following error.

Try running it this way:

test_results=$(python -m pytest)
echo $test_results

Awesome that worked. Thank you.

I don’t suppose you know how to do the same thing but with in a Windows env?

I don’t have a windows machine handy to test, but something like this, maybe?

$test_results = python -m pytest
Write-Output $test_results

if we are talking powershell.
