module GoodData
module Mixin
# When an RSpec test like this fails,
#
# @my_array.should == [@some_model, @some_model2]
#
# RSpec will call inspect on each of the objects to "help" you figure out
# what went wrong. Well, inspect will usually dump a TON OF SHIT and make trying
# to figure out why `@my_array` is not made up of `@some_model` and `@some_model2`.
#
# This little module and technique helps get around that. It will redefine `inspect`
# if you include it in your model object.
#
# You can define a whitelist of methods that inspect will dump.
# It will always provide `object_id` at a minimum.
#
# To use it, drop it in spec/support/inspector.rb and class_eval the models to
# override `inspect`.
