# frozen_string_literal: true
# Split's helper exposes all kinds of methods we don't want to
# mix into our model classes.
#
# This module exposes only two methods:
#  - ab_test()
#  - ab_finished()
# that can safely be mixed into any class.
#
# Passes the instance of the class that it's mixed into to the
# Split persistence adapter as context.
