Integration testing a cloud native application with JavaScript｜
summary
Walks through testing a cloud‑native app on AWS that uses MQTT to webhooks and REST, driven with JavaScript and a BDD/gherkin setup, showing a working test runner that deploys real stacks into a separate account, verifies webhooks via an API Gateway + SQS receiver, and copes with async delays using exponential backoff. Calls out 3,500 lines of CloudFormation that forced adoption of CDK in TypeScript, introduces the open‑source test runner/defrost and shows the approach actually running and catching timing/cold‑start issues.
