-------------------------------------
Summary: Unit testing main methods is hard
Key: SAMZA-387
URL: https://issues.apache.org/jira/browse/SAMZA-387
Project: Samza
Issue Type: Bug
Components: container, yarn
Affects Versions: 0.8.0
Reporter: Chris Riccomini
Both SamzaAppMaster and SamzaContainer are hard to unit test. I ran into this
as part of SAMZA-382, but it's a recurring problem. The issue is that we have a
lot of logic in the main() method that's not mockable.
I think a good solution would be to write a helper class for things like
environment variable, JmxServer, etc, and manage them all cleanly in an object
that we can test, rather than in the main() method.
