Subject [jira] [Commented] (LUCENE-4463) add support for running the same test method many times
Date Fri, 05 Oct 2012 21:28:04 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13470678#comment-13470678

Robert Muir commented on LUCENE-4463:
-------------------------------------

Here is my current script, just so you see:

{noformat}
#!/bin/bash
> /home/rmuir/log.txt
x=0
while [ $x -lt 1000 ]
do
  echo "test iteration number $x"
  ant test -Dtestcase=TestFoo -Dtests.method=testBar >> /home/rmuir/log.txt 2>&1

  x=$(( $x + 1 ))
done
{noformat}

I edit this every time i need to use it and then just use 'grep -i failed log.txt' to look
for failures.
one problem is it fires up ant, calls resolve,compile,compile-tests all this stuff each time.
this makes it really slow.
so if it could work from ant directly i think it would be much more efficient.

> 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 :)
