Create test cases for MultiProbeTableScanResultSet with duplicates in the probe
list
------------------------------------------------------------------------------------
Key: DERBY-4378
URL: https://issues.apache.org/jira/browse/DERBY-4378
Project: Derby
Issue Type: Improvement
Components: Test
Affects Versions: 10.6.0.0
Reporter: Knut Anders Hatlen
Priority: Minor
See the coverage report for MultiProbeTableScanResultSet:
http://dbtg.foundry.sun.com/derby/test/coverage/jvm1.6/sol/suitesAll82289/_files/401.html
There are three red lines (lines that are not exercised by the tests).
Adding a test case where the probe list contains duplicate values will exercise
the first red line in getNextProbeValue().
If the duplicates are also the last elements in the probe list, the other two
red lines (in getNextProbeValue() and reopenScanController()) will be exercised
too.
Note that MultiProbeTableScanResultSet will sort the probe list, so the last
element in the probe list is not necessarily identical to the last element in
the query's IN list. It will also remove duplicates at compile time, if
possible, so the IN list needs to contain parameters.
