Subject [jira] Commented: (DERBY-2949) AssertionFailedError in testStalePlansOnLargeTable
Date Fri, 03 Dec 2010 20:26:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2949?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12966657#action_12966657
] 

Lily Wei commented on DERBY-2949:
---------------------------------

+1 for making test behaves predictable. Tests are meant to raise potential issues not to add
variation of the issue. I can see leaning toward to selects from the FLUSHER table with explicit
checkpoints is a good balance for this case. However, the goal of the test was very good.
I am not aware of whether we have test to fill the page cache with new data, evicting all
pages currently in the cache so the row count changes are written at a known point in time.
And, it will be a good test to have in turn of code coverage point of view.
