-------------------------------------
[~navina]
Yes, I'm interested in this patch and I think it's valuable for everybody
trying to implement unit tests for stream tasks.
It would be great if it could be included in the next release, 0.11.0.
Thanks Navina!
> Create a unit test harness to easily test samza tasks
> -----------------------------------------------------
>
> Key: SAMZA-681
> URL: https://issues.apache.org/jira/browse/SAMZA-681
> Project: Samza
> Issue Type: Test
> Components: test
> Affects Versions: 0.9.0
> Reporter: Luis De Pombo
> Attachments: SAMZA-381.patch
>
>
> 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.
