In Rails 4.1+, they deprecated db:test:prepare with that message. You can now just use:

ActiveRecord::Migration.maintain_test_schema!

in spec_helper.rb (or similar files if you're not using RSpec). That will automatically keep your test database in sync with your schema. Because of this 'automatic' method, db:test:prepare is no longer needed in most cases.

If you need to do it manually for some reason, you can still use

rake db:schema:load RAILS_ENV=test
