I would love it if you could expand on this. I currently work with AWS Lambdas a lot and have tried a couple options for running them locally but never got to a point where it was worth the effort. For example I use PyCharm and tried getting the aws serverless plugin working with it for running Lambdas and State Machines but just kept running into different problems.

There must be a better approach than setting up a bunch of mocks and running the core logic in a scratch file.
