Subject [jira] [Comment Edited] (CASSANDRA-7712) temporary files need to be cleaned by unit tests
Date Sat, 13 Sep 2014 19:10:34 GMT

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

Quick digging seems to indicate the correct way to handle this would be to call deleteOnExit
in an @After method.  Junit isn't shutting the jvm down uncleanly, just failing the test out.

> There are many unit test temporary files left behind after test runs. In the case of
CI servers, I have seen >70,000 files accumulate in /tmp over a period of time. Each unit
test should make an effort to remove its temporary files when the test is completed.
> My current unit test cleanup block:
> {noformat}
> # clean up after unit tests..
> rm -rf  /tmp/140*-0 /tmp/CFWith* /tmp/Counter1* /tmp/DescriptorTest* /tmp/Keyspace1*
