schema.rb vs. migrations

Should you use schema.rb or the migrations to initialize the in-memory database? schema.rb is the default and generally faster. Reasons for using migrate: true could be to help make sure your migrations don't break due to changes in the code elsewhere (whether this is useful depends on your use-case), or to make some seeding data be available. If those reasons don't apply, keeping it at the default is probably faster.

TL;DR: Use the default unless there's a clear reason not to. You can always switch later.
