There's nothing wrong with testing the configuration before starting the web server.

The config is tested during restart, by the ExecStartPre. If you modify a config and you want to restart, you should execute nginx -t prior to restarting your service - but generally you'd want to use nginx -s reload as much as possible.

What's the purpose of testing the configuration file in the systemd
example?
Just starting the server seems simpler.. and the test isn't run prior to a
restart request.


ExecStartPre=/usr/sbin/nginx -t
