This portion of the repository contains test samples for Java based serverless projects.
| Project | Description |
|---|---|
| Java Starter Project | An introductory example of Java AWS Lambda and Amazon API Gateway integration test. This is the best place to start! |
| API Gateway to Lambda to DynamoDB | An example of simple serverless microservice with Amazon API Gateway, Java AWS Lambda and Amazon DynamoDB with tests. |
| Step Functions Local Testing | An example of testing Step Functions workflow locally using JUnit, Spock test framework, and Testcontainers. |
| Springboot with DynamoDB Application | Synchronous sample SpringBoot application written in Java which performs customer CRUD operations. AWS serverless services like Amazon API Gateway, ALB, ECR, Fargate, DynamoDB & SQS being used to host and test the application flow. |
| GraphQL using AppSync | An implementation of the backend GraphQL API using Java with AWS Java SDK 2.x and AWS SAM. |
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.

| Project | Description |
|---|---|
| Lambda with DynamoDB | You may use a variety of resource types to create the event listener for your asynchronous system under test. We recommend starting with AWS Lambda and Amazon DynamoDB. DynamoDB creates a persistent storage resource that can enable long running tests or an aggregate a set of results. |
| Schema & Contract Testing | This project contains examples on how to do schema and contract testing for your event driven applications. |
