Sandy Ryza commented on SPARK-4159:
-----------------------------------
[~pwendell] [~srowen] After this change it looks like the wiki's advice on how
to run a single test
(https://cwiki.apache.org/confluence/display/SPARK/Useful+Developer+Tools) no
longer holds.
{code}
mvn test -DwildcardSuites=org.apache.spark.io.CompressionCodecSuite
{code}
will fun that single Scala test and all Java tests.
I was able to work around this with:
{code}
mvn test -DwildcardSuites=org.apache.spark.io.CompressionCodecSuite
-Dtest=nothing -DfailIfNoTests=false
{code}
is there anything we can do in the build to fix this or should I just change
the wiki?
> Maven build doesn't run JUnit test suites
> -----------------------------------------
>
> Key: SPARK-4159
> URL: https://issues.apache.org/jira/browse/SPARK-4159
> Project: Spark
> Issue Type: Bug
> Components: Build
> Reporter: Patrick Wendell
> Assignee: Sean Owen
> Priority: Critical
> Labels: backport-needed
> Fix For: 1.3.0
>
>
> It turns out our Maven build isn't running any Java test suites, and likely
> hasn't ever.
> After some fishing I believe the following is the issue. We use scalatest [1]
> in our maven build which, by default can't automatically detect JUnit tests.
> Scalatest will allow you to enumerate a list of suites via "JUnitClasses",
> but I cant' find a way for it to auto-detect all JUnit tests. It turns out
> this works in SBT because of our use of the junit-interface[2] which does
> this for you.
> An okay fix for this might be to simply enable the normal (surefire) maven
> tests in addition to our scalatest in the maven build. The only thing to
> watch out for is that they don't overlap in some way. We'd also have to copy
> over environment variables, memory settings, etc to that plugin.
