Subject [jira] [Commented] (LUCENE-4463) Add support for running the same test method/class many times with different class seeds
Date Sat, 06 Oct 2012 11:33:03 GMT


Uwe Schindler commented on LUCENE-4463:

bq. Btw. I don't think there's anything I can do to make Mike NOT run his Python/SSH magic
because he scatters tests across a farm of machines... I plan to do this for junit4 around
year 2020, he, he. Not that it's very complicated technically but it'd require a lot of refactorings
and then testing for potential infrastructure problems, detecting hung processes/sockets/jvms,

I dont think you need to do that: He should install Jenkins on his farmhouse machine and then
setup a slave in the GUI for every combine harvester operated by his slaves. He can then create
a job, not bound to a specific node and run it on all slaves in parallel. Very easy to setup,
the SSH-Magic is included in Jenkins ("dumb slave "): Jenkins connects via SSH to the slave,
copies the slave.jar via scp and starts the jenkins cows. On the dairies you don’t need
to setup anything beyond a VM in $PATH.

> 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 :)
