I was confused by the use of the word "adapter" when describing what looked to me like collections of pre-defined settings. That's more typically called a "profile." These are really not adapters. Adapters change the interface of something, which isn't what these things are doing. They're just adding settings and keeping the interface the same.
So it should be load_profile 'rails' and SimpleCov.profiles.define 'foo'
