[Exploration] Creating Integration Tests

[jfuss]

Currently, it can be challenging to write reliable integration tests against serverless applications.
We want to explore ways this process can be made easier using SAM CLI (Serverless Application Model Command Line Interface), and need your feedback. Here are a few ideas we are thinking about -

Manage timeouts and retries for tests targeting event driven applications
Optimize test execution time
Auto generate test payloads for a set of AWS services

Please feel free to drop your ideas/requests pertaining to integration testing in the comments. Specifically, what are the sticky issues you run into when writing tests for serverless applications on AWS? Do the ideas above accurately address the pain points?
