> We don't have a standardized test framework for unit testing samza tasks. Currently, in order to test the proper functionality of a task we have to bring up the system (kafka) and its dependencies (zk).
> Goals:
> - The harness should abstract several notions around the system and its partitions, without mocking them, and hold task context and state in memory.
> - The harness should let you inject several <key,value> pairs that would normally be passed in by the `SystemStream` provided in `tasks.input`.
> - The same harness should offer an interface to visualize all the corresponding <key,value> pairs collected in the message `Collector`, which are the output of the `process`ed or `window`ed input <key,value> pairs previously injected.
