Overview

Note:

This class is intended for use in development, for example if you want to verify what events your instrumented code is sending. Use in production is not recommended.

For debugging use: a mock version of TransmissionClient that simply prints events to stderr or a file for inspection (and does not send them to Honeycomb, or perform any network activity).
