Since August 2017, AWS has provided SAM local which allows lambda functions to be run locally.

https://docs.aws.amazon.com/lambda/latest/dg/sam-cli-requirements.html

The AWS SAM CLI is a command line tool that operates on an AWS SAM template and application code. With the AWS SAM CLI, you can invoke Lambda functions locally, create a deployment package for your serverless application, deploy your serverless application to the AWS Cloud, and so on.

You need docker - to start your lambda locally. If you are in admin / docker group you can connect to the process with your profiler.
