Jesse Anderson commented on CRUNCH-322:
---------------------------------------
Then I'd recommend changing the unit tests in
src/test/java/org/apache/crunch/fn/ that currently use StoreLastEmitter to
start using InMemoryEmitter. That was how I finally found some unit test
examples for Crunch.
I'd also add a something about unit testing to the new user guide.
> StoreLastEmitter Should Be Part of crunch-test

> Key: CRUNCH-322
> URL: https://issues.apache.org/jira/browse/CRUNCH-322
> Project: Crunch
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.9.0
> Reporter: Jesse Anderson
> Assignee: Josh Wills
>
> There aren't many ways of unit testing Crunch that are built in. I'm using
> crunch-core/src/test/java/org/apache/crunch/fn/StoreLastEmitter.java to test
> outputs from DoFN classes.
> This class is not distributed with the crunch-core JAR because it is in the
> test package. This class should be moved to the non-test source for
> crunch-test.
