[jira] [Created] (LUCENE-4460) Test exception handling
better/easier than testThreadInterruptDeadlock()
Robert Muir created LUCENE-4460:
-----------------------------------
Summary: Test exception handling better/easier than testThreadInterruptDeadlock()
Key: LUCENE-4460
URL: https://issues.apache.org/jira/browse/LUCENE-4460
Project: Lucene - Core
Issue Type: Bug
Components: general/test
Reporter: Robert Muir
currently the fact that MockDirectoryWrapper has throttlers and such that sleep, combined with the fact this test interrupts, makes a good test for exception handling.
The problem is this is really crappy to debug: things dont reproduce, you have to use hundreds or thousands of iterations, etc etc.
I think it would be better if we made it possible for MockIndexInput to throw random exceptions like MockIndexOutput and had a single threaded test that just threw random exceptions? This way it would reproduce...
