In your earlier post you mention Django 1.2 but the reference you quote
above is the dev documentation. There are differences in the docs but
I'm not sure what the underlying code differences might be.

You are right though. If you want to test commits and rollbacks
TransactionTestCase is your thing. By my reading of both 1.2 and dev
docs, vanilla TestCase imported from Django on the other hand should
handle commits and rollbacks itself.

As to your second database, I can't help because I have zero experience
with multiple databases. However, I think I have recently seen a caveat
in the docs somewhere about testing with multiple database. I haven't
looked in the 1.2 docs for some time.
