Too tired of setting your local domain each time you create new virtual development domain, etc helloworld.test, unit.test point to 127.0.0.1
There is a better way to achieve that by using dnsmasq, then set up a wildcard domains for development. In this case I use .test because .dev has been owned by Google and they strictly use HTTPS in mainly browsers.
$ brew install dnsmasq
Adding .test wildcard to config file
$ echo 'address=/.test/127.0.0.1' > $(brew --prefix)/etc/dnsmasq.conf
Setup dnsmasq as a startup service
$ sudo brew services start dnsmasq
127.0.0.1 (dnsmasq IP) as first DNS resolver
System Preferences > Network > Wi-Fi > Advanced... > DNS > add 127.0.0.1 > move it to top of the list.
Checking everything is worked by listing all resolvers
$ scutil --dns
Try it out
$ nslookup -type=a something.test
