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.
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
To create an a/b test merely define the following.
<%= ab_test "example test", ["variation one", "variation two"], user_id do |variation| %>
<% if variation == "variation one" %>
<p>
Variation one
</p>
<% end %>
<% if variation == "variation two" %>
<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.
