Sure, We (Prabhat and I) have done some testing for this feature 
internally but never published the test-scripts on this forum. PFA the 
sql scripts ( along with the expected .out files) we have used for 
testing for your ready reference.

In addition we had generated the LCOV (code coverage) report and 
compared the files which are changed for the "Parallel index scan" patch.
You can see the numbers for  "with patch" V/s "Without patch"  (.pdf 
file is attached)
