Celluloid actors

[LTe]

I have problem with Bogus and Celluloid. Bogus expects that Method object will be respond to name method. But Celluloid::Method does not respond for this method.

How to reproduce:

# celluloid_spec.rb
class Actor
  include Celluloid

  def test_method
    puts "hello"
  end
end

require 'rspec'
require 'bogus/rspec'

describe Actor do
  fake(:actor)

  before { stub(subject).test_method { "value" } } 

  it "returns value" do
    subject.test_method.should == "value"
  end
end

And we can execute spec for that

Failures:

  1) Actor returns value
     Failure/Error: before { stub(subject).test_method { "value" } }
     NoMethodError:
       undefined method `name' for #<Celluloid::Method Actor#test_method>
     # ./celluloid_method.rb:17:in `block (2 levels) in <top (required)>'

I created workaround for that: https://github.com/LTe/dht/blob/master/spec/support/celluloid_method.rb

Solutions:

1. Create pull request to celluloid.
2. Bogus should display information about problem with method object.
3. Add information to wiki about - how to test celluloid actors.

This is definitely an issue with Celluloid, because they overwrite Ruby's standard reflection, without preserving the old interface. The fix is rather trivial (Celluloid::Method just needs to respond to name and parameters).

Would you like to create the pull request to Celluloid, or should I?

But when you or library will modify Method object would be nice when Bogus will inform developer about problems. For example:

Hey developer! Bogus depends on original Method object and probably this object has been modified which can cause problems

Or something like that :)

Yes I will create pull request to Celluloid

I created pull request for Celluloid https://github.com/celluloid/celluloid/pull/300

Thanks for the workaround LTe. First day yesterday using both celluloid and bogus I got hit by this.
