Evented requests

  • @synchrony

As an API consumer

I want to perform evented requests

Because that has some business value.

Scenarios
Evented request
Given
the following: 
require 'sucker/synchrony'

@request = Sucker.new(
  key:       amazon_key,
  secret:    amazon_secret,
  locale:    'us')
@request << {
  operation: 'ItemLookup',
  id_type:   'ASIN',
  item_id:   '0826490786' }
When
I tape: 

EM.synchrony do
  @response = @request.get
  EM.stop
end
Then
I expect: 
@response['Item'].count.should eql 1
Multiple evented requests executed in parallel
Given
the following: 
require 'sucker/synchrony'

@asins   = %w{ 0816614024 0143105825 0485113600 }
@locales = Sucker::Request.locales

@request = Sucker.new(
  key:        amazon_key,
  secret:     amazon_secret)
@request << {
  operation: 'ItemLookup',
  id_type:   'ASIN' }
When
I tape: 
EM.synchrony do
  concurrency = 6

  @responses = EM::Synchrony::Iterator.new(@asins.product(@locales), concurrency).map do |(asin, locale), iter|
    @request.locale = locale
    @request << { item_id: asin }
    @request.aget { |response| iter.return(response) }
  end

  EM.stop
end
Then
I expect: 
@responses.map { |response| response['Title'] }.size.should eql 18
