Answer 2

I can see the advantages of local testing. Take a look at these open source projects:

1. lambda-local: test Lambda functions on your local machine with sample event data
2. emulambda: a Python wrapper that emulates the AWS Lambda API locally

Also see this Stack Overflow post: How to test aws lambda functions locally.

Our command-line tool, bst proxy, does exactly what you are looking for: https://bespoken.tools/blog/2016/08/24/introducing-bst-proxy-for-alexa-skill-development

It will make your lambda code accessible via URL, which you can then test with yourself or use with a real Alexa device. To use it, you install bst with npm:

sh
npm install bespoken-tools -g

And then run it:

bst proxy lambda index.js

You can then use the URL that is printed out to test away.
