---------------------------------------
Hi [~eyal]
Let me know if i start working on this.
> Improve test cases
> ------------------
>
> Key: DATAFU-164
> URL: https://issues.apache.org/jira/browse/DATAFU-164
> Project: DataFu
> Issue Type: Test
> Reporter: Eyal Allweil
> Priority: Major
> Labels: good-first-issue, newbie, up-for-grabs
>
> We can get better code coverage and cover edge cases that are currently
> missing in our main tests file,
> [TestSparkDFUtils|https://github.com/apache/datafu/blob/master/datafu-spark/src/test/scala/datafu/spark/TestSparkDFUtils.scala].
>
> For example, another test for
> [joinWithRange|https://github.com/apache/datafu/blob/master/datafu-spark/src/main/scala/datafu/spark/SparkDFUtils.scala#L419]
> that includes the case that a record falls into
> {{{}decreased_range_single{}}}, but {{range_start}} and {{range_end}} do not
> contain {{single.}}
> Another case for the
> [flatten|https://github.com/apache/datafu/blob/master/datafu-spark/src/main/scala/datafu/spark/SparkDFUtils.scala#L256]
> API could also be good.
> Or for
> [dedupRandomN|https://github.com/apache/datafu/blob/master/datafu-spark/src/main/scala/datafu/spark/SparkDFUtils.scala#L567].
> Or for anything else, for that matter.
>
> It's perfectly alright to only do one of them - either as a patch or GitHub
> PR.
