I've always found it hard to get the Nginx config right and have at times done the following:

1. Run Nginx (or OpenResty in my case) in Docker

2. Have the config files in a volume

3. Have a script (Python, Bash or anything else) which watches the config files for changes, then first runs `nginx -s reload` in the Nginx container, and then executes a number of unit tests

For Emacs users there's also an nginx-mode which makes a bit more pleasant to edit the config files.
