A/B Testing With Rails (In 5 Easy Steps)

Step 1: Start using Vanity in your Rails application:

Rails::Initializer.run do |config|
gem.config "vanity"

config.after_initialize do
  require "vanity"
end
end

And:

class ApplicationController < ActionController::Base
use_vanity :current_user
end

Step 2: Define your first A/B test. This experiment goes in the file experiments/price_options.rb:

ab_test "Price options" do
description "Mirror, mirror on the wall, who's the better price of all?"
alternatives 19, 25, 29
metrics :signups
end

Step 3: Present the different options to your users:

Get started for only $<%= ab_test :price_options %> a month!

Step 4: Measure conversion:

class SignupController < ApplicationController
def signup
  @account = Account.new(params[:account])
  if @account.save
    track! :signups
    redirect_to @acccount
  else
    render action: :offer
  end
end
end

Step 5: Check the report:

vanity report --output vanity.html
