How to run some environment setting cmd before pytest in VSCode

[shaoqx]

I was running VSCode on a remote server which most environments are loaded by module load xxx.
Is there any way to run some command before the actual pytest with the Test function of VSCode? I tried use conftest.py but it does not work.

Not specifically. Can you run the commands before you load VS Code? Otherwise you can try to use a debugging configuration to tweak things and run your tests under a debugger. The last option I can think of is specifying a different script for the path to pytest and have that do the loading for you.

Beyond that the only thing I can think of is using something like subprocess to run the command for you (assuming it doesn't need to set environment variables).

Thank you for the answer!
"run the commands before you load VS Code"
This looks good but how should I do this? I tried running the command before the test but the test seems to run in a different shell (?) that those command are not applied.
"use a debugging configuration"
This looks great but I'm not very familiar with debugging in general for python. Should I use the suggested startup.py to load those commands?
"specifying a different script for the path to pytest"
By this, you mean like setting the path to a script that load some command first and than mimik pytest?

I would just run the command in your terminal before you launch VS Code from the same terminal.

Should I use the suggested startup.py to load those commands?

That's totally up to you on how you choose to do it. But my suggestion was more around whether launch.json offered something that you could use.

Yep!
