Makers

Minimalistic factories to replace fixtures in rails.

I did this gem to:

• Enforce better practices removing unnecessary options.
• Avoid the need to use another method to build/create lists.
• Quicker syntax to handle associations.

Put this line in your Gemfile:

gem 'makers', group: [:development, :test]

Then bundle:

$ bundle

Generate de definitions file:

$ bundle exec rails g makers:install

The file will be put in test/makers.rb or spec/makers.rb depending on your test framework:

Makers.define do
end

Just concatenate makers:

Makers.define do

  maker :user do
    name 'example'

    maker :user_with_email do
      email 'example@mail.com'
    end
  end

end

Generates an unique sequence of numbers for an attribute:

Makers.define do

  maker :user do
    sequence(:email) { |n| "example#{n}@mail.com" }
    sequence(:phone)
  end

end

Associations are defined by name or by the association method:

Makers.define do

  maker :user do
    posts
    comments 4, strategy: :create
  end

  maker :comment do
    association :user
  end

  maker :post do
    user
  end

end

Aliases can be assigned in the initialization:

Makers.define do

  maker :user, aliases: :author do
    comments
  end

  maker :post, aliases: %i(comment article) do
    title
    author
  end

end

If you need to use some logic that depends of another attribute you can use a block:

Makers.define do

  maker :user do
    name 'example'
    email { "#{name}@mail.com" }
    sequence(:username) { |n| "#{name}-#{n}" }
  end

end

There are two new methods available in tests:

build
create

Is possible to override the defaults passing a hash:

build :user, name: 'other'
create :category, title: 'other'

To create lists just pass the desired size as second parameter:

build :user, 2, name: 'other'
create :category, 5, title: 'other'

Any issue, pull request, comment of any kind is more than welcome!

I will mainly ensure compatibility to Rails, AWS, PostgreSQL, Redis, Elasticsearch and FreeBSD.
