> WordCount unit test plus a helper class to facilitate testing Mappers and
> Reducers
> ----------------------------------------------------------------------------------
>
> Key: HADOOP-1936
> URL: https://issues.apache.org/jira/browse/HADOOP-1936
> Project: Hadoop
> Issue Type: Test
> Components: examples
> Reporter: Kate Rhodes
> Priority: Trivial
> Attachments: WordCountTestExampleAndOutputCollectorTestHelper.patch
>
>
> There are to pieces to this The first is a test for WordCount, not because
> word count actually needed one but because it would be useful to beginners to
> have an example of how to unit test Mappers and Reducers.
> The second piece is AOutputCollector and it's associated unit test
> TestAOutputCollector. This is an abstract class that can be quickly extended
> by a stub OutputCollector in your unit tests to collect the output from your
> Mapper and Reducer tests and make it available for easy retreival when
> testing to see if the fourth key that was emitted was the one you expected.
> I think that this would be a useful tool to have in the main test folder but
> wasn't sure where would be best to put it. Also, since nothing else in Hadoop
> uses Hungarian notation you'll probably want to rename it. I didn't because
> I'm not confident about the naming conventions here and figured that since it
> and its test probably wouldn't end up living in the same folder as WordCount
> that you could just rename it when you moved it.
