Learn how to test your serverless applications
summary
Explains how to test Lambda code with concrete tools and patterns: use SAM CLI to locally invoke and step through functions, run unit, integration and end to end tests, and provision ephemeral test stacks from SAM templates so environments stay consistent. Recommends polling for final state rather than fixed sleeps, add a dead letter queue and zero retry to surface delivery errors, use pre-traffic hook and post hooks plus canary deploys for safe deploys, and orchestrate test runs with Step Functions.
