Simplifying cloud-native app testing across environments
summary
Claim: developers can run and test cloud‑native Spring apps locally without full clusters by combining Testcontainers, Dapr and Microcks. A three‑service pizza demo runs with only the store process: Dapr sidecar abstracts Kafka/Postgres so apps have no broker or DB deps and Microcks generates mocks and contract tests from OpenAPI/AsyncAPI, including async Kafka/cloud‑events checks. Demo shows simulated kitchen/delivery work, contract tests validate serialization and topic delivery (demo uses a 4s wait; callback support is planned), and switching brokers or managed services requires no code changes.
