Localhost on the server for tests?

Question

PHPUnit

How to create a server for unit tests (PHPUnit)?
I heard somewhere (I don’t remember where) that for this purpose you can create a local host on the server?
I just don't quite understand how to organize it.

Answer 1

You can, for example, set up Gitlab and run tests in it
