Knut Anders Hatlen commented on DERBY-4347:
-------------------------------------------
We could also just increase the default wait time. It shouldn't have any
negative effects except that it takes longer for the test to fail if the server
doesn't start, but that's hardly worth optimizing for.
Minor nit: If we add the system property, I think it would be better to specify
the number of seconds to wait instead of milliseconds, as I don't see the need
for ms resolution. It would also be more in line with the other (non-testing)
timeout properties like derby.locks.*timeout.

> Key: DERBY-4347
> URL: https://issues.apache.org/jira/browse/DERBY-4347
> Project: Derby
> Issue Type: Improvement
> Components: Test
> Affects Versions: 10.5.3.0, 10.6.0.0
> Reporter: Kathey Marsden
> Priority: Minor
>
> 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.
