Weird failure behavior with TestCase for payment app ?

[Darren Hollenbeck]

In the minimum order test case for the payment app, I am getting a failure when testing under my development store setup. What's weird is that the assertion failure will happen in different spots (2 of them), but putting a pdb trace point in and stepping through the test case code results in success. I suspect there's some kind of timing thing going on where some of the transactions are not occurring before the next assertion test is done, thus causing a failure. I cannot reproduce this when using a fresh demo/skeleton store setup (clonesatchmo).

Error text and trace point insertion below...

Sometimes this one:

Creating test database for alias 'default'...
Skipping creation of NoticeTypes as notification app not found

Other times I get this:
