```ruby
FactoryGirl.define do
  factory :user do
    name "Winston Smith-Churchill"
    sequence(:github_id)
  end

user
```ruby
FactoryGirl.define do
  factory :user do
    name 'Winston Smith-Churchill'
    sequence(:email) {|n|
      "user#{n}@example.org"
    }
    provider 'google'
    sequence(:provider_uid)
    sequence(:image_url) {|n|
      "http://example.org/users/#{n}.jpg"
    }
  end
end
