Famili
Yet Another ObjectMother pattern implementation for rails testing
Why
We meet some problems with factory-girl:
-
We require quite complex logic for creation of test models
-
We require use factories with running rails application for integration tests
-
So why don’t make factory just another class in rails lib, and get extensibility of factories/mothers and rails lazy loading and dependency management?
Example
To define factory/mother for model User just create class in your lib directory:
#lib/famili/user.rb`
module Famili
class User < Mother
fist_name { 'nicola' }
last_name { 'nicola' }
email { "#{last_name}@mail.lv" }
def before_save(user)
#...
end
def after_create(user)
#...
end
end
end
#lib/famili/article
module Famili
class Article < Mother
#creating association
user { Famili::User.create }
title { "article by #{user.last_name}" }
end
end
And u can use it anywhere in tests or controllers:
Famili::User.create(:fist_name=>'Override') # create model
Famili::User.build(:fist_name=>'Override') # build model not saving
Famili::User.hash(:fist_name=>'Override') #get attributes hash
Famili::Article.create #create article with user
Inheritance
U can inherite mothers just like plain ruby classes, Just think each declaration field_name … as method definition
module Famili
class User < Mother
name { "nicola" }
end
class Person < User
email { "#{name}@emial.com" }
end
end
Mother methods
Mother have some usable methods, which can be used
module Famili
class User < Mother
last_name { 'nicola' }
login { "#{last_name}_#{unique}" }
number { sequence_number }
end
end
-
sequence_number - incremented with each instance
-
unique - just unique string
-
we a planing add more
Nutshell
each declaration
field_name { block }
just create method
def field_name
end
and register attribuite to copy in model
field :field_name
Install
in config/environment.rb:
config.gem 'famili'
and then
sudo rake gems:install
FEATURES
CHANGE LOG:
-
0.0.1 - created
-
0.0.2 - add inheritance, and mother methods [unique,sequence_number]
-
0.0.3 - fix Mother.create call model.save!; Mother.hash return symbolized hash
-
0.0.5 - add raise NoMethodError if property declared without block (becose it is error-prone), fix Famili::Mother.class#name method
-
0.0.6 - rename Mother#hash to Mother#build_hash (to avoid conflicts with Object#hash in Ruby 1.9). Old name keeped as alias when using with oldest versions of Ruby for backward compatibility.
