Subject [jira] [Commented] (LUCENE-3785) Replace ant macros for running concurrent tests with ant-junit4.
Date Mon, 20 Feb 2012 19:59:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13212039#comment-13212039
] 

Dawid Weiss commented on LUCENE-3785:
-------------------------------------

I talked to Robert a bit and I've decided to postpone the commit until I have the backport
on 3x branch ready too. It would make everyone's life very difficult if I applied it to the
trunk only because of differences in acquiring the Random instance from LTC.

I'll work on the backport and come back when I'm ready.

> ant-junit4 is an ANT task for running tests in parallel (on slave JVMs). Its advantages
over the current macros:
> - dynamic load balancing based on historical test runs and current execution (job-stealing),
> - jvm-crash resilience (I wrote tests that actually crash a slave jvms to make sure such
an event is reported appropriately),
> - nicer console reporting (no need for syserrs on LuceneTestCase level).
> More documentation and info will follow as I roll out a patch.
> NOTE. The code for this issue is being developed at:
