ValidatesCnpj

Validates cnpj and test it in a simple way. Supports ruby 2.2+ and rails 3+.

Add this line to your application's Gemfile:

gem 'validates_cnpj'

And then execute:

$ bundle

Or install it yourself as:

$ gem install validates_cnpj

Just use as any other validator:

class Company < ActiveRecord::Base
    validates :cnpj, cnpj: true
end

To force the attribute to be masked pass option mask:

class Company < ActiveRecord::Base
  validates :cnpj, cnpj: { mask: true }
end

Require the matcher:

require 'validates_cnpj/require_a_valid_cnpj_matcher'

Use in your tests:

it { is_expected.to require_a_valid_cnpj } # It will test the attribute :cnpj by default
it { is_expected.to require_a_valid_cnpj(:id) }
