Testing my API changes with Perl

I have an API. I like some things about it, but it was kinda clunky in many ways.

I rewrote it. I thought I had everything together, used the same SQL queries, but I wanted to be sure it kicked out the same output.

So, I wrote tests using Perl's Test::Most and cmp_deeply().

A few weeks ago, I knew Perl testing existed but I didn't know much about it. Now it's practical.
