How to create virtual host outside DocumentRoot?

Question

Apache HTTP Server

There is a default configured Apache.
DocumentRoot is registered in httpd.conf, for example,
/Users/user_name/server

Now I want to create a virtual host and go to httpd-vhosts.conf
and write there

<VirtualHost *:80>
 ServerName test.localhost
 ServerAlias test.localhost
 VirtualDocumentRoot "/Users/user_name/some_folder"
 DocumentRoot "/Users/user_name/some_folder"
</VirtualHost>

As a result, I get 403 forbidden at test.localhost.
I believe this is because the original (httpd.conf) DocumentRoot is different from the one in .

Actually, the question is:
How and is it even possible to scatter virtual hosts in completely different places that differ from the original DocumentRoot ?
If possible, what and where should I write to make it work?

UPDATE:
Played with the rights a little. Now I go to the site normally, but instead of the site I see an Index of / and a list of pages.
.htaccess is set up fine. Working sites that I transfer to the same folder also become Index of /
In Apache logs like this:

client denied by server configuration: /Users/user_name/some_folder/.htaccess

Answer 1

I guess this is because the original (httpd.conf) DocumentRoot is different from the one in

Not because of this.
Add to VirtualHost

<Directory "/Users/user_name/some_folder">
    Require all granted
</Directory>
