lambda-harness 1.0.0

Test harness for AWS Lambda

Sets up and executes Python code in a method highly analogous to the Lambda runtime environment.

Current notable gaps include:

• No support for runtime or memory limits

• No support for intra-execution cgroup freeze/thaw

Other than these caveats, it should look and feel roughly like a real Lambda execution, including all the correct environment variables, data structures, and log messages.

Check out the page on GitHub for complete documentation.

Example
