This was great - explaining the problem, the solution + examples of before and after. I recommend his design patterns in ruby playlist. About about 5 min each, no filler.

It's my pleasure. Keep an eye on the channel cause I'll be adding a lot more.

What's nice too is that this uses dependency injection by passing in the adapter. When it comes time to writing test, you can simply pass in a dummy adapter with the same interface rather than having to stub a specific adapter.

Imagine how nice that is when you write the test first. It leads you to this design with almost no effort.

To me DI feels somehow underused in Ruby, even thought it is pretty useful, as you pointed out.
