-----------------------------------

             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...
