title: AWS Lambda: Java Integration testing
body: <p>Is there way to build proper integration test for few AWS Lambdas interacting each other via AWS SNS topic?</p>
  
  <p>I deployed two lambdas using Java. </p>
  
  <ul>
  <li>The first one is subscribed to AWS SNS_topic#1. It filters and transforms SNS message and pushes modified data onto SNS_topic#2.</li>
  <li>The second one lambda is subscribed to SNS_topic#2. It modifies SNS message and do http request onto external endpoint.</li>
  </ul>
  
  <p>I need to build end-to-end Integration test to check whole interaction.</p>
