Question

我有一个类使用the aws-sdk-rails gem（aws-sdk-ruby v2上的包装器）读取/处理来自SQS队列的消息。如何模拟AWS调用以便我可以测试我的代码而无需访问外部服务？

communicator.rb ：

define( 'DB_NAME', ..... (redacted code for security)
...........................

define('AUTH_KEY'......         
..........................

我很难找到模拟AWS资源的示例。我花了几天时间搞清楚，并希望在Stack Overflow上分享我的结果以供后代使用。我使用了rspec-mocks（doubles＆amp; verifying doubles)。这是问题中include(dbsalts.php);示例的示例。

<强> communicator_spec.rb ：

class Communicator
  def consume_messages
    sqs_client = Aws::SQS::Client.new
    # consume messages until the queue is empty
    loop do
      r = sqs_client.receive_message({
                                              queue_url: "https://sqs.region.amazonaws.com/xxxxxxxxxxxx/foo",
                                              visibility_timeout: 1,
                                              max_number_of_messages: 1
                                     })
      break if (response.message.length == 0)
      # process r.messages.first.body
      r = sqs_client.delete_message({
                                      queue_url: "https://sqs.region.amazonaws.com/xxxxxxxxxxxx/foo",
                                      receipt_handle: r.messages.first.receipt_handle
                                    })
    end
  end
end

AWS SDK已提供存根。剂适量http://docs.aws.amazon.com/sdkforruby/api/Aws/ClientStubs.html了解更多信息（与官方文档相关联。）
