"If We Had A Test Suite" to the tune of "If I Were A Rich Man"
“If I Were a Rich Man” “If We Had a Test Suite”
Original by Katie
(lyrics from http://www.stlyrics.com/lyrics/fiddlerontheroof/ifiwerearichman.htm)
[TEVYE] [TURNER]
"Dear God, you made many, many poor people. Dear team, we wrote lots and lots of crufty code.
I realize, of course, that it's no shame to be poor. I realize, of course, that everyone writes some hacks.
But it's no great honor either! But it’s not great practice either!
So, what would have been so terrible if I had a small fortune?" So, what would have been so terrible if we’d refactored a bit?

Design Problem

I'm struggling to balance encapsulation with managing side effects in a specific scenario described here.

Classes

  • PriceSettings < ActiveRecord::Base (side-effect-based class methods, value-based instances) stores user parameters for price calculations
  • APIClient (adapter object) fetches statistics from an external API to use in price calculations
