A rails gem for absurdly simple a/b testing
Redis (tested with 1.2.6, 2.2.2) Rails (tested with 3.0.10, 3.1.0)
gem "absurdity"
Put this in an initializer, for expample config/initializers/redis_absurdity.rb: Absurdity.redis = Redis.new(:host => "localhost", :port => 6379)
Note: More often you will use a redis.conf to set up your redis client, the important part is to assign your redis client instance to Absurdity.redis . Don’t forget to start your Redis server.
mkdir "absurdity" in your rails app root directory
touch "absurdity/experiments.yml"
define your experiments in this file:
:experiments:
:wild_side:
:metrics:
- :fun
- :hangover
:variants:
- :with_music
- :without_music
:walk:
:metrics:
- :sun
- :rain
:variants:
- :slow
- :fast
:completed:
:fast
:wild_side will be the name of your experiment
[:fun, :hangover] will be the metrics you wish to track
[:with_music, :without_music] will be the variants you wish to vary
the :walk has been marked as completed.
You should identify which variant to show here (:fast).
Now everyone will only see the :fast variant.
And, no one will produce any metric tracking.
Note: You can't use the shortform for declaring an array of symbols in ruby 1.9.2 and Psych.
So instead of using :metrics: [:fun, :hangover] use the longer form shown above.
def create Absurdity.track! :fun, :wild_side, current_user.id end
def my_helper variant = Absurdity.variant :wild_side, current_user.id if variant == :with_music Play.music else Play.nothing end end
/absurdities => linked list of experiments /absurdities/experiment_name => show experiment
