Knut Anders Hatlen commented on DERBY-5100:
-------------------------------------------
Some of the test methods in this test (and also in NetworkServerControlApiTest
- see DERBY-5115) depend on the connections having a certain connection number.
This is only possible to guarantee if the test methods are invoked in a
particular order, or if we restart the network server between each test method.
I suggest that we explicitly order the methods in this test and add a comment
saying why the order is required. I'll add a utility method that sorts the
tests alphabetically, and then we can add a serial number to the test names to
define the order (test_01_blahblah, test_02_blahblah, ...).

> Key: DERBY-5100
> URL: https://issues.apache.org/jira/browse/DERBY-5100
> Project: Derby
> Issue Type: Bug
> Components: Test
> Affects Versions: 10.8.0.0
> Reporter: Knut Anders Hatlen
>
> The test cases in GetCurrentPropertiesTest must run in the order in which
> they are defined in the source file. If for example the test case
> testPropertiesTraceOn runs first, the test will fail with the following stack
> trace:
> 1)
> testPropertiesTraceOn(org.apache.derbyTesting.functionTests.tests.derbynet.GetCurrentPropertiesTest)junit.framework.ComparisonFailure:
> expected:<[tru]e> but was:<[fals]e>
