The documentation for testing artifacts (http://docs.cask.co/cdap/develop/en/developers-manual/testing/testing.html#strategies-in-testing-artifacts) is out-of-date, in that the referenced file (BaseETLBatchTest) no longer exists.
It needs to replace references to cdap-etl-batch with cdap-data-pipeline, and show how to:
- add an artifact containing an application class
- deploying an application using that artifact
- add plugins that extend that artifact
