Validates cpf and test it in a simple way.
Supports ruby 2.2+ and rails 3+. For older ruby versions use the version `2`.

## Installation

Add this line to your application's Gemfile:

    gem 'validates_cpf'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install validates_cpf

## Usage

Just use as any other validator:

```ruby
class User < ActiveRecord::Base
  validates :cpf, cpf: true
end
```

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

```ruby
class User < ActiveRecord::Base
  validates :cpf, cpf: { mask: true }
end
```

## Testing

Require the matcher:

```ruby
require 'validates_cpf/require_a_valid_cpf_matcher'
```

Use in your tests:

```ruby
it { is_expected.to require_a_valid_cpf } # It will test the attribute :cpf by default
it { is_expected.to require_a_valid_cpf(:id) }
```
