Should hash keys be sorted?

We already sort keys for ActiveRecord::Base instances, so it may make sense to sort hash keys too.

Thinking about this some more, I don't think hash keys should ever be sorted. I think we should use the expected value as the source of truth for how keys should appear, because oftentimes you're looking at a failing test and comparing the output to what you've written. In other words you don't know what the actual value is, but you do know what the expected value is (because you wrote it).
