Github Scientist example

README.md

GitHub's Scientist gem provide's a framework for running and publishing experiments, however, I found their code snippets a little confusing. They confused me because the examples were either too simple (that is, did not demonstrate the publishing feature) or they were incomplete (that is, they assumed the user had some implementation correctly setup and just needed to add code to make it run).

This is the shortest hello world style example which demonstrates publishing I could figure out.

scientist_example.rb

require 'scientist'

class Greeter
  include Scientist
  include Scientist::Experiment

  def initialize(*args)
  end

  def greeting
    science "say_hello" do |experiment|
      experiment.use { "hello" }
      experiment.try { "hola" }
    end
  end

  def enabled?
    true
  end

  def publish(result)
    p result
  end
end

# replace `Scientist::Default` as the default implementation
module Scientist::Experiment
  def self.new(name)
    Greeter.new(name: name)
  end
end

puts Greeter.new.greeting
