Yes. I believe the methods all raise AssertionError on failure, and the 
test methods are wrapped with try:.. except AssertionError as err:

    if missing:
      raise ValueError('invoices %r missing from batch' % missing)

should be "assertEqual(missing, [], 'invoices missing from batch')" and 
if that fails, the non-empty list is printed along with the message.
