This portion of the repository contains code samples for testing serverless applications using Python.
| Project | Description |
|---|---|
| Python Starter Project | This project contains introductory examples of Python tests written for AWS Lambda. This is the best place to start! |
| Lambda local testing with Mocks | This project contains unit tests for Lambda using mocks. |
| Lambda Layers with Mocks | This project contains unit tests for Lambda layers using mocks. |
| API Gateway with Lambda and DynamoDB | This project contains unit and integration tests for a pattern using API Gateway, AWS Lambda and Amazon DynamoDB. |
| Schema and Contract Testing | This project contains sample schema and contract tests for an event driven architecture. |
| Kinesis with Lambda and DynamoDB | This project contains a example of testing an application with an Amazon Kinesis Data Stream. |
| SQS with Lambda | This project demonstrates testing SQS as a source and destination in an integration test |
These projects have excellent in-depth examples of unit and integration tests for API based applications.

In a synchronous system, a calling service makes a request to a receiving service and then blocks, waiting for the receiver to complete the operation and return a result. In contrast, in an asynchronous system, a caller makes a request to a receiving system, which typically returns an immediate acknowledgement but then performs the requested operation at a later time. Asynchronous systems are frequently designed using event-driven architectures. These types of systems have several advantages including increased reliability, greater control over load processing, and improved scalability. However, testing these systems can present unique challenges.
