ChankoAb

Installation

Add this line to your application's Gemfile:

gem 'chanko_ab'

And then execute:

$ bundle

Or install it yourself as:

$ gem install chanko_ab

Usage

# Define logging code and identifier
# e.g.
ChankoAb.logging do |name, attrs|
  Rails.logger.debug(name)
end

ChankoAb.identifier digit: 1, radix: 10, extractor: -> (ctx) do
  ctx.cookies[:identifier][-1]
end

# And then, prepare ab test chanko unit.
module MySplitTest
  include Chanko::Unit
  include ChankoAb

  split_test.add_cohort name: :default, attributes: {}
  split_test.add_cohort name: :pattern1, attributes: { partial: "partian1" }

  split_test.log_template name: 'show' template: 'my_split_test.[name]'

  split_test.define(:new_text, scope: :view) do |cohort|
    cohort.log('show')
    context.instance_eval do
      case cohort.name
      when 'default'
        run_default
      else
        render cohort.attributes[:partial]
      end
    end
  end
end

Switch using identifier

module MySplitTest
  ...

  split_test.identifier digit: 1, radix: 10, extractor: -> (ctx) do
    ctx.cookies&.then do |cookies|
     cookies.[:identifier][-1]
  end
  ...
end

Use HexIdentifier if identifier is composed by hex.

module HexMySplitTest
  ...
  split_test.identifier digit: 1, radix: 16, extractor: -> (ctx) do
    ctx.cookies[:hex_identifier][-1]
  end
  ...
end
