Testing Cloud-Native Applications With Ease!
summary
Shows how Testcontainers + LocalStack run real AWS-compatible services in Docker so tests are repeatable and isolated, including creating S3 buckets, DynamoDB tables and deploying a Java Lambda thumbnail generator (zip, create-function, invoke) within tests. Demonstrates JUnit and Quarkus DevServices integrations, automatic on‑demand service startup in LocalStack 2.0, container lifecycle and cleanup, and an option to run containers remotely via Testcontainers Cloud so CI or locked developer machines can still execute the same end‑to‑end tests.
