Subject [jira] Commented: (DERBY-2543) testVirtualMemoryHeap junit test fails with "Virtual memory heap test failed! Got unexpected value. expected:<202> but was:<103>"
Date Fri, 13 Apr 2007 21:16:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12488786
] 

Ugo Matrangolo commented on DERBY-2543:
---------------------------------------

I was checking why the test passes when executed alone and fails in a suite.

My first thought was that other tests can influence the derby.language.maxMemoryPerTable=1
property; a simple println() revealed
that it is not the case. Running the test in a suite doesn't affect this value.

I composed a little suite with :

suite.addTest(UpdateCursorTest.suite());
suite.addTest(DistinctTest.suite());       
suite.addTest(GroupByTest.suite());

and the test did ok. Then I tried :

suite.addTest(DistinctTest.suite());       
suite.addTest(UpdateCursorTest.suite());      
suite.addTest(GroupByTest.suite());

and the test failed. Both times the property was ok.

I'm investigating what changes between these two cases.

Hope this helps.
