Subject [jira] Commented: (DERBY-4347) Provide a property to increase network server start timeout for JUnit tests
Date Mon, 31 Aug 2009 19:59:32 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12749593#action_12749593
] 

Kathey Marsden commented on DERBY-4347:
---------------------------------------

I seem to recall concern that increasing the default wait time might mask actual network server
start performance regressions.   Seconds instead of milliseconds sounds fine.

>  Sometimes when running JUnit tests with jvm options that are known to slow things down
significantly network server start timeouts can occur e.g.
> SecureServerTest( Opened = false, Authenticated= false, CustomDerbyProperties= null,
WildCardHost= null )junit.framework.AssertionFailedError: Timed out waiting for network server
to start:Spawned SpawnedNetworkServer exitCode=143

>      */
>     private static final long WAIT_TIME = 40000;

> It would be nice to have system property (maybe derby.tests.networkServerStartTimeout=<ms>)
 to allow this to be configurable in environments where we expect the start to take longer.
> I am not sure if there are other timeouts in the tests for replication etc or if they
all use this same setting.
