After AWS introduced AppSync Events, I decided to revisit my old post on testing Event-Driven Architectures. This time, I use AppSync Events instead of Momento Topics to test my application end-to-end.

Testing Serverless applications end-to-end is difficult. Testing distributed systems is difficult. But with the right tools, it can be made easier. Learn how to use Momento Topics to test that your application(s) produces the EventBridge events you expect.

Learn how to reliably publish domain events in Serverless applications using the Transactional Outbox Pattern. Get the reliability your events deserve with DynamoDB Streams and Transactions while keeping your domain layer clean and complexity low.
