Subject [jira] Updated: (DERBY-1764) Rewrite stress.multi as a JUnit test
Date Thu, 09 Oct 2008 21:18:44 GMT

     [ https://issues.apache.org/jira/browse/DERBY-1764?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kathey Marsden updated DERBY-1764:
----------------------------------

    Attachment: DERBY-1764_sysprops_diff.txt

Attached is a patch that enables the test and uses SystemPropertiesTestSetup for setting the
system properties for embedded.  I added a staticproperties flag to SystemPropertiesTestSetup
that will  cause the engine to shutdown on setup and teardown so that the properties take
effect.   It is still not  perfect but I would like to check it in as an incremental improvement.
 The SystemPropertyTestSetup  works fine for the embedded test but not for network server
because it causes protocol errors and not for encrypted because the database cannot booted
after it has been shutdown.  So I did the SystemPropertiesTestSetup only for embedded.  

Another problem is that the database will get deleted after the test run, so the property
to keep the transaction log is really not that useful.  I plan to change BaseTestCase to 
save off the database if the test fails.  I'll open up another issue for that change.

I ran suites.All (hit only DERBY-3719) , StressMutli10x1,StressMulti50x59

> Currently, stress.multi consists of a number of sql scripts that are run in ij. It often
fails with cryptic error messages, and since it uses ij, there is often no stack trace. It
would be very useful to rewrite the test in JUnit so that we can get better error messages
and stack traces when it fails.
