# FakeRecord Mimics ActiveRecord::Base, so you can use your record like a model.
#   It needs its subclasses to define two methods:
#   - initialize(*args, &block) for create and build to work, and
#   - save! for create and save to work.
#   save! is supposed to raise a RecordNotSavedError when the record couldn't be
#   saved, e.g. because of validation errors.
