Adding parallel JUnit task

[Jason Rutherglen-2]

Hello, please excuse the newbie question.
For the Apache Lucene project I'd like to paralleize the unit tests by
subclassing JUnitTask into ParallelJUnitTask which executes JUnitTests in
threads.

I don't understand how to place things like <batchtest> into the new
<paralleljunit> task tag properly.  Here's what I've tried in the build.xml:

<paralleljunit xmlns="antlib:org.apache.lucene.ant" printsummary="off"
haltonfailure="no" maxmemory="512M">
      <contrib-settings />
      <formatter type="xml"/>
      <formatter type="brief" usefile="false"/>
      <batchtest fork="yes" todir="@{junit.output.dir}" if="runall">
        <fileset dir="@{dataDir}" includes="${junit.includes}"
excludes="${junit.excludes}"/>
      </batchtest>
      <batchtest fork="yes" todir="@{junit.output.dir}" if="testpackage">
        <fileset dir="@{dataDir}"
includes="**/${testpackage}/**/Test*.java,**/${testpackage}/**/*Test.java"
excludes="${junit.excludes}"/>
      </batchtest>
      <batchtest fork="yes" todir="@{junit.output.dir}"
if="testpackageroot">
        <fileset dir="@{dataDir}"
includes="**/${testpackageroot}/Test*.java,**/${testpackageroot}/*Test.java"
excludes="${junit.excludes}"/>
      </batchtest>
      <batchtest fork="yes" todir="@{junit.output.dir}" if="testcase">
        <fileset dir="@{dataDir}" includes="**/${testcase}.java"/>
      </batchtest>
  </paralleljunit>

I've been thinking of an extra junit4 task in its own antlib, this could
go alongside it. I've also done a junit3 runner for hadoop, runs each
test suite as a separate task...

simply needs to add a jar to their existing project. Hadoop sounds great as
well.

Hi Jason.

It is an interesting insight. This junit runner for Hadoop you've mentioned,
would it actually allow to parallel an execution of a bunch of tests on a
multi-way hardware? Or it would require someone to make manual split of tests
into separate test suites first?

Is the source code is available anywhere?

Thanks for any information you can share
