No, I do not.

But again, where is your "careful test plan" please? All I have seen
from you so far is asking us to provide you with a careful test plan
while dancing carefully around every single attempt to get a look at
what you got so far.

I have written PostgreSQL regression tests. I have done consistency
checks of entire ERP systems prior to data conversion attempts. I know
the value of tests, whether they are against software or data. May I ask
what you've done so far?

I personally think you don't actually ever did any software testing
yourself. You are not really talking from experience, are you? So
please, show me what you have now, or get one more plus on my minus-list.
