Minimalist library for build objects as test data. Inspired by FactoryGirl
Fabricas is simple; just a few lines of code. It's a framework agnostic library with zero requires and zero monkey-patching of any class or object. Very useful when you need to build objects fast.
Installing Fabricas is as simple as running:
$ gem install fabricas
Include Fabricas in your Gemfile with gem 'fabricas' or require it with require 'fabricas'.
class User
attr_accessor :name, :email
end
Fabricas.define do
factory :user do
name "Julio"
email "[email protected]"
end
end
user = Fabricas.build :user
puts user.inspect
#=> <User @name= "Julio", @email= "[email protected]">
other_user = Fabricas.build :user, name: "Pedro"
puts other_user.inspect
#=> <User @name= "Pedro", @email= "[email protected]">You can provide your own class name to your factories using the class_name key:
Fabricas.define do
factory :employee, class_name: "User" do
name "Dilbert"
area "Engineer"
end
end
employee = Fabricas.build :employee
puts employee.inspect
#=> <User @name= "Dilbert", @area= "Engineer">Also you can use blocks in your factory to send whatever you want.
Fabricas.define do
factory :user do
# ...
password { User.generate_password }
city { Faker::Address.city }
end
endYou can take advantage of them for sending other instances.
class Pet
attr_accessor :name, :age
end
Fabricas.define do
factory :user do
# ...
pet { Fabricas.build :pet }
end
factory :pet do
name "Firulais"
age 12
end
end
user = Fabricas.build :user
puts user.pet.inspect
#=> <Pet @name= "Firulais", @age= 12>Attributes can be built using other attributes
Fabricas.define do
factory :user do
name "Julio"
url "workingawesome.com"
email { "#{name.downcase}@#{url}" }
end
end
user = Fabricas.build :user
puts user.inspect
#=> <User @name= "Julio", @url="workingawesome.com", @email= "[email protected]">By using inheritance, your factory child can receive the same attributes and class name of its parent.
Fabricas.define do
factory :user do
first_name "Julio"
email "[email protected]"
factory :admin do
access true
end
end
end
user = Fabricas.build :user
admin = Fabricas.build :admin
puts user.inspect
#=> <User @name= "Julio", @email= "[email protected]">
puts admin.inspect
#=> <User @name= "Julio", @email= "[email protected]", @access= true>
