There are a few ways to improve the feedback loop, like SAM, Stackery, and Serverless Framework. That said, containers on Lambda (or GCP Cloud Run) are where it’s at. Just code your code, run local unit tests, and push the container up. The most important thing is to clearly define a mock request from your invocation source as your first step of the project. There is a vast difference between SQS, ALB and API Gateway events that need to be accounted for, and trip up people on deployment. I usually have those in my tests folder for every event the code will handle, and build from there. ‘aws lambda invoke -e myevent.JSON’ goes a long ways, because you get the full response object back.
