Jelly Bird gem

Lightweight library for building objects in test/spec case's.

Travis CI

instalation

type gem install jelly_bird

or add to bundler ( test group )

"jelly_bird", :git => "[email protected]:JakubOboza/jellybird.git"

usage

assuming you have class called Dummy with two properties name and number you can create test factory this say:

      Dummy.define {{
        :name => /\w{3,8}/.gen,
        :number => /\d\d\d\d\d\d/.gen
      }}

to generate object in test just use .gen like this Dummy.gen to get generated object

example

class Dummy < Hash; end

Dummy.define {{
  :name => /\w{3,10}/.gen
}}

10.times { puts Dummy.gen[:name] }

dummy = Dummy.gen
# dummy[:name] => random generated /\w{3,10}/ compilant word

other_dummy = Dummy.gen(:name => "dummy name")
# other_dummy[:name] => "dummy name"

custom factories

you can define custom factories, and generate object using .generate method with factory name like this.

Mummy.define {{
  :left  => /\w{3,10}/.gen,
  :right => /\w{3,10}/.gen
}}

Mummy.define(:custom) {{
  :center => /\w{3,10}/.gen
}}

mummy = Mummy.generate(:custom, :mumble => true)

in fact .gen is just calling generate with :default symbol.

generate with hook

user = User.gen {|user| user.save }

doing this returns you object which received :save after generating

integration with rspec

touch a file with defines like factories.rb in spec folder and then require it inside of your spec_helper.rb. Then define all the factories like this.

User.define {{
  :first_name => /\w{3,9}/.gen,
  :last_name  => /\w{3,8}/.gen,
  :email      => /\w{3,8}@\w{3,8}\.com/.gen
}}

Family.define {{
  :father      => User.gen,
  :mom         => User.gen,
  :kind        => User.gen,
  :family_name => /\w{3,8}/.gen
}}

remember that if you wanna embbed one into another please don't specify them at random order :).

Now just use it in tests!

Don't forget about {{
