AbTests

AbTests is a simple gem for creating and deploying new a/b tests with only a simple addition of some ruby code in a view.

For serious applications, I would recommend reading the source code of this gem and rolling your own version for easy customization.

Installation

Add this line to your application's Gemfile:

gem 'ab_tests'

And then execute:

$ bundle
$ bundle exec rails g ab_tests:install
$ bundle exec rake db:migrate

Or install it yourself as:

$ gem install ab_tests

Usage

To create an a/b test merely define the following.

<%= ab_test "example test", ["variation one", "variation two"], nil do |variation| %>
  <% if variation == "variation one" %>
    <p>
      Variation one
    </p>
  <% end %>
  <% if variation == "variation one" %>
    <p>
      Variation two
    </p>
  <% end %>
<% end %>

The ab_test helper takes the following arguements: test_name, an array of variation names, and a unique user idenitfier (optional).

The results of the tests are stored in the variations table.

Currently, AbTests does not support variation percentages. To date I've only had to run 50/50s and other evenly proportioned tests and I merely removed the variations when I have picked a winner.
