Hi,
I am working on DERBY-6317(Optmizer can choose the wrong path when
BTreeCostController.java returns an estimate cost and row count of
0.0) and have a stand alone reproducible test case. The program has to
create a very large db to reproduce the problem.
Now, I am working on writing a junit test and having the junit test
create a similar db but the problem does not reproduce. I am wondering
if it is possible(for experimental purposes) for the junit test to
pick up an existing db(the one I have created from stand alone
reproducible case) and run the test fixtures against it to reproduce
the problem. This will verify for me that the test fixture is working
fine when working against a known reproducible db.
Yes, you can put a copy of your database in place as system/wombat and
the test will pick that up for your testing.
thanks,
Mamta
