What would be the best scenario for a test site with EE

Hi. I am using EE to create WP site on VPS. I’d like to create a test site on VPS in a subdomain, show it to the customer and then I will delete it or move to the to real site.

So… I know the commands - how to create WP site with Easy Engine.

But how can i create Wordpress Site into a subdomain (not multisite)

And how to remove that later, without breaking the production VPS server?
