Mamta A. Satoor commented on DERBY-4834:
----------------------------------------

I ran all the junit and derbyall tests after backporting this jira to 10.6 and didn't run into any issues. I have committed the backport to 10.6 with revision 1336993.

> Dealing with index statistics in the JUnit tests require some tedious work, like looking up table and index ids,  doing selects on the SYS.SYSSTATISTICS table, and analyzing the results of these queries.
> To make life easer and the tests easier to read, a set of utility methods will be added to a new class living in the JUnit test framework package.
