Local Testing and Debugging with SAM CLI
Run and debug your serverless functions on your own machine before deploying. Use sam local to invoke functions, emulate API Gateway, and iterate fast.
Why Test Locally?
Deploying to AWS just to test a change is slow. The SAM CLI emulates Lambda and API Gateway locally using Docker, so you can iterate in seconds.
Prerequisites
Local invocation needs:
- Docker running
- The SAM CLI installed
- A valid
template.yaml
