Validates cnpj and test it in a simple way

## Installation

Add this line to your application's Gemfile:

    gem 'validates_cnpj'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install validates_cnpj

## Usage

Just use as any other validator:

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

To force the attribute to be masked pass option `mask`:

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

## Testing

Require the matcher:

```ruby
require 'validates_cnpj/require_a_valid_cnpj_matcher'
```

Use in your tests:

```ruby
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) }
```
