Testing Cloud Applications Without Breaking the Bank: Testcontainers & LocalStack
summary
Claims a concrete setup: Testcontainers + LocalStack spin up AWS emulations, create SQS queues and S3 buckets, run Playwright-driven UI flows, then clean up. The repo contains the code and Docker Compose used. Examples show an end-to-end test that retries until the async SQS→processor→S3 step appears and it works in local and CI. Costs drop because no real cloud calls are made, but emulation gaps remain for performance or exotic services.
