Michael McCandless commented on LUCENE-4463:
--------------------------------------------
The "scatter tests across a bunch of networked machines" script is here:
http://code.google.com/a/apache-extras.org/p/luceneutil/source/browse/runRemoteTests.py
... it just uses randomizedrunner to execute the tests, but ssh to distribute
each test case to the N machines. All JVMs (N per remote machine) pull from a
single shared tasks queue, in order of slowest test to fastest test ... it
communicates with randomizedrunner using its nice stdin/.events "API" :)
It runs [nearly!] all Lucene/Solr tests across N machines and reports any
failures ... the source code is scary and has hardwired constants for my env
... but it makes running all tests wicked fast.
But that's a very different use case than "beasting a single test" (this
issue). For that I use
http://code.google.com/a/apache-extras.org/p/luceneutil/source/browse/repeatLuceneTest.py
... however, it's single threaded, and does not run on remote machines ...
would be fun to fix that!
bq. He should install Jenkins on his farmhouse machine and then setup a slave
Well I think we need to solve this issue first (how to run many iters of a
single testcase & testmethod, each w/ a different seed)? Then I agree Jenkins
could be used for distribution instead of ssh + scripts.

> I have a shell script for this, mike has a python script, its annoying :)
> I want to do something like this:
> ant beast -Dtestcase=XXXX -Dtestmethod=YYYY -Diterations=100
> I would be happy with a simple loop that just invokes 'test' somehow: getting
> a fresh new JVM to each iteration is desirable anyway (so you get fresh
> codecs, etc).
> the -Dtests.iters is not really useful for this because it does not allow
> -Dtestmethod and it does not give a fresh jvm.
> bonus points if it can use multiple jvms at the same time though :)
