If you host is, say "zeus.barrera.io" you can use: test-service-1.zeus.barrera.i...

It's not about shared hosts (at least if I'm understanding the topic correctly) but about /etc/hosts entries on your local machine for your local machine. As in:

    my-test-thing-a.dev 127.0.0.1
    my-test-thing-b.dev 127.0.0.1
    my-test-thing-c.dev 127.0.0.1

Buying an actual registered domain for that sounds like it would be even more confusing than using an unregistered TLD because it makes it hard to tell which hostnames are expected to work across machines and which are strictly "works on my machine".
