What is the best way to deploy an existing project for testing?

Question

git

Friends, such a question. There is a heavy news site on Wordpress, it is required to make some adjustments in it, but due to the fact that the site is constantly alive and working, it is required to carry out work on the test.
I worked very little with git and therefore I ask for advice on how to properly set up the
dev - production environment? to edit everything on the test and then send it to production.
Maybe someone develops sites on WP in a similar way.

Answer 1

What you have asked is not a git question. These are SDLC questions - and only you can answer those questions.
Git is just a versioning tool, not a content delivery tool.
Moreover, it is not even known that your site is spinning on a virtual machine or on a hosting, and in principle it is possible to install git there or not.
Yes, git can also synchronize changes between different environments, but here are the questions that you ask - you yourself must come up with a convenient pipeline and select tools (git, scp, rsync, some thread CI / CD tool or whatever)
