Building and Testing Serverless API Applications with AWS SAM

The primary draw for implementation of AWS serverless applications is the supposed simplicity. Anyone that has attempted to implement testing on a serverless application, however, knows that it is anything but simple. Serverless technologies allow for the faster construction of more complex applications with more complex integrations while also providing new technologies and execution environments, all of which pose a challenge to those used to testing in a more traditional way. This presentation looks at an API-based serverless application as an example and introduces how the application may be built using a tool known as SAM (Serverless Application Model) with testing in mind. Additionally, specific testing approaches and strategies, including local simulated tests and deployed cloud-based tests, will be shared. Attendees will walk away from this presentation with a greater understanding of what a serverless application is and how they might want to test it.
