Subject [jira] [Commented] (LUCENE-6194) Reproduce with should include -Dtests.iters=N
Date Thu, 22 Jan 2015 10:17:34 GMT


Dawid Weiss commented on LUCENE-6194:

If reiterations are independent then the failure reproduce-with message should point you at
the failing iteration, without the need to loop through any previous seeds... At least in
an ideal world this should be the case?

> I was playing with the patch on LUCENE-6066, and hit a test failure, but then the "Reproduce
with: " failed to reproduce, which threw me for a bit of a loop, until I realized it was missing
the -Dtests.iters=N.

-Dtests.slow=true -Dtests.linedocsfile=/lucenedata/hudson.enwiki.random.lines.txt -Dtests.locale=ru_RU
-Dtests.timezone=Europe/Paris -Dtests.asserts=true -Dtests.file.encoding=UTF-8 -Dtests.iters=10
> {noformat}
> (or just insert a random test failure into e.g. TestDemo or something).
> It should fail, but the "Reproduce with: ..." line does not include -Dtests.iters=10.
 I think it should?
