How can I run 'tox' tests using HassIO?

Hi I’m developing a custom component and I’m using HassIO.

However in order for it to be used in HA it needs to pass ‘tox’ tests.

How can I do these tests on HassIO OS?

I couldn’t see tox in the /usr/src/homeassistant/script/ folder but I did find lazytox.py!

Is tox not supported on HassIO?

Would running HA under VENV be a better option here?

I would say, to develop, use the venv installation. More on this with the following guide : https://developers.home-assistant.io/docs/en/development_environment.html

Thanks, I’ve got another SD card so I’ll try a VENV install on Raspbian and see how it goes.
