# Dither
Collection of combinatorial test generation strategies.

# Usage

Use 2-Way IPOG
```ruby
require 'dither'

results = Dither.ipog([[true, false],
                      [:cat, :dog, :mouse],
                      (0...3).to_a])

results.each { |a| puts "#{a}" }

# output
[true,  :cat, 0]
[true,  :dog, 1]
[true,  :mouse, 2]
[false, :cat, 0]
[false, :dog, 1]
[false, :mouse, 2]
[true,  :cat, 0]
[true,  :dog, 1]
[true,  :mouse, 2]
```

Use 3-Way IPOG

results = Dither.ipog([[true, false],
                       [true, false],
                       [:cat, :dog, :mouse],
                       (0...5).to_a], :t => 3)

results.each { |a| puts "#{a}" }

# output
[true, true, :cat, 0]
...
```

# Note on Patches/Pull Requests

* Fork the project.
* Make your feature addition or bug fix.
* Add tests for it. This is important so I don't break it in a
  future version unintentionally.
* Commit, do not mess with rakefile, version, or history.
  (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
* Send me a pull request. Bonus points for topic branches
