Usage

install

add your Gemfile gem 'senju_kan_non'

or $ gem install senju_kan_non

in your spec

SenjuKanNon.redeem(first_group: [1,2,3], second_group: [9,8,7])

SenjuKanNon.redeem returns nested array like below: [[1, 9], [1, 8], [1, 7], [2, 9], [2, 8], [2, 7], [3, 9], [3, 8], [3, 7]]

you can use each pair for your spec repeatedly(maybe you should use rspec-retry).
