PJ Fanning commented on SPARK-18896:
------------------------------------
I noticed from the pull request that you are looking at possibly upgrading
scalatest too. Getting to scalatest 3.0.1 would be useful for later scala 2.12
support. Scalatest 2.x is not cross compiled for Scala 2.12.
> Suppress ScalaCheck warning -- Unknown ScalaCheck args provided when
> executing tests using sbt

> Key: SPARK-18896
> URL: https://issues.apache.org/jira/browse/SPARK-18896
> Project: Spark
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 2.2.0
> Reporter: Jacek Laskowski
> Priority: Trivial
>
> While executing tests for {{DAGScheduler}} I've noticed the following warning:
> {code}
> > core/testOnly org.apache.spark.scheduler.DAGSchedulerSuite
> ...
> [info] Warning: Unknown ScalaCheck args provided: -oDF
> {code}
> The reason is due to a bug in ScalaCheck as reported in
> https://github.com/rickynils/scalacheck/issues/212 and fixed in
> https://github.com/rickynils/scalacheck/commit/df435a5 that is available in
> ScalaCheck 1.13.4.
> Spark uses [ScalaCheck
> 1.12.5|https://github.com/apache/spark/blob/master/pom.xml#L717] which is
> behind the latest 1.12.6 [released on Nov
> 1|https://github.com/rickynils/scalacheck/releases] (not to mention 1.13.4).
> Let's get rid of ScalaCheck's warning (and perhaps upgrade ScalaCheck along
> the way too!).
