[jira] [Created] (LUCENE-3036) TestFSTs.testRealTerms is a terrible
unit test
TestFSTs.testRealTerms is a terrible unit test
----------------------------------------------
Key: LUCENE-3036
URL: https://issues.apache.org/jira/browse/LUCENE-3036
Project: Lucene - Java
Issue Type: Bug
Reporter: Robert Muir
This test:
* uses FSDirectory.open (platform-specific behavior)
* is a random test, but runs to a certain amount of seconds, then quits (makes it hard to reproduce with seed, as its behavior is dependent on your computers speed etc)
After waiting 3 hours to download the 1 gigabyte file to reproduce the corrupt index it made in (https://hudson.apache.org/hudson/job/Lucene-trunk/1533/testReport/junit/org.apache.lucene.util.automaton.fst/TestFSTs/testRealTerms/), I found some of this frustrating.
I managed to finally reproduce it but its no fun fiddling with a test that runs for 5 minutes to reproduce a fail.

-------------------------------------
also, i don't like that the test data file hudson uses for nightly tests seems to only be available on hudson itself. this limits debugging fails to pmc members. we should put this file somewhere public.
