 # Lambda-local
-============
 
 [![Build Status](https://travis-ci.org/ashiina/lambda-local.svg?branch=develop)](https://travis-ci.org/ashiina/lambda-local)
 
 Lambda-local lets you test Amazon Lambda functions on your local machine with sample event data.
 The `context` of the Lambda function is already loaded so you do not have to worry about it.
 You can pass any `event` JSON object as you please.
