Writing tests for workers

[langalex]

Provide a way to write automated tests for workers. The tests should include building the code package to ensure all files and gems are required correctly.

@romand-ironio it's for you. suggestion - add method for code package which will show list of files and runtime-specific things (like gems).

I basically created this ticket as a conversation starter. Basically what I would like to see are two things:

integrated

A way to run workers as part of an integration test suite (in-process). Here's what I'm doing right now:

# a helper for testing workers
# to use a helper just call TestWorkers::<WorkerName>.perform(params)
module TestWorkers
  def self.const_missing(name)
    path = Rails.root.join('workers')
    $LOAD_PATH << path.to_s unless $LOAD_PATH.include?(path.to_s)
    code = File.read(path.join(name.to_s.underscore + '.rb'))
    klass = Class.new
    klass.class_eval "attr_reader :params
    def perform(_params)
      @params = JSON.parse(_params.to_json) # deep stringify keys
      #{code}
    end", __FILE__, __LINE__
    const_set name, klass
    klass
  end
end

And then in a test:

TestWorkers::MyWorker.new.perform :x => :y

Isolated

A way to test a worker in an isolated way to make sure all its dependencies are correct. This would probably use

IronWorkerNG::Code::Base.new(:workerfile => workerfile).run

so what's missing here IMHO is maybe an integration with RSpec.

Can you please come to support channel @ http://get.iron.io/chat so we can discuss?

[langalex]

sorry don't have time at the moment. happy to contribute here from time to time.

[iced]

any time - we usually have 2-3 devs sitting there.
