object-history

Test your objects with history path.

http://travis-ci.org/LTe/object-history.png

Instalation

Add to your Gemfile gem 'object-history'

How to use

Just include ObjectHistory to class. class TrackedObject include ObjectHistory end

And on bottom of class add the methods that you want to track class TrackedObject include ObjectHistory track_history_of :your_method end

Examples

Track object

class TrackedObject attr_accessor :number

def initialize(child = nil)
  @number = 0
end

def add_one(*args, &block)
  @number += 1
  block.call(self) if block_given?
end

include ObjectHistory
track_history_of :add_one
end

After that you can test with rspec using have_track matcher ;-)

describe TrackObject do
before(:each) do
  @track_object = TrackObject.new
end

it "should every execute add one to :number" do
  3.times {@track_object.add_one}
  @track_object.should have_track(:number, [0,1,2,3])
end
end

Post example

class Post attr_accessor :status

def initialize
  @status = :new
end

def accept
  @status = :accepted
end

def send_post
  @status = :sent
end

def load
  @status = :loaded
end

include ObjectHistory
track_history_of :accept, :send_post, :load
end

And Rspec before(:each) do @post = Post.new end

it "should have [:new, :loaded, :accepted, :sent] path" do
@post.load
@post.accept
@post.send_post

@post.should have_track(:status, [:new, :loaded, :accepted, :sent])
end

Accessors

class Accessor attr_accessor :version

def initialize
  @version = 0
end

include ObjectHistory 
track_history_of :version=
end

Rspec before(:each) do @accessor = Accessor.new end

it "should track accessor" do
  @accessor.version = 5
  @accessor.version = 10

  @accessor.should have_track(:version, [0,5,10])
end

Deep clone?

Works

method_missing?

Fuck method_missing ;*. Just deal with it.

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
