Installing

gem install pairwise

Usage

Pairwise and Ruby

Pairwise.combinations will return an array of input combinations.

Here’s an example using pairwise with Rspec:

require 'rubygems'
require 'pairwise'

describe “something” do
Pairwise.combinations([1,2], [1,2], [2,3]).each do |(event_id, new_event_id, media_id)|
it “should do something with these input values” do

end
end
end

Pairwise and Cucumber

Create a yaml file with your inputs:

event with image: [Football, Basketball, Soccer]
event without image: [Football, Basketball, Soccer]
media: [Image, Video, Music]

If you want to force the ordering of your inputs:

- event with image: [Football, Basketball, Soccer]
- event without image: [Football, Basketball, Soccer]
- media: [Image, Video, Music]

Run pairwise passing the input file

$ pairwise inputs.yml

This will output a table ready to be used in your Cucumber features.


| media | event without image | event with image |
| Image | Football            | Football         |
| Image | Basketball          | Basketball       |
| Image | Soccer              | Soccer           |
| Video | Football            | Soccer           |
| Video | Basketball          | Football         |
| Video | Soccer              | Basketball       |
| Music | Football            | Basketball       |
| Music | Basketball          | Soccer           |
| Music | Soccer              | Football         |
