Can bank name be tested here instead of being ""?

[Shanfeng, 2017/03/10 21:49:57]

This is intended.
This test case is to verify the database migration function works properly. We
don't know the bank name of a card without a downstream sync. So when we add the
bank name column to the table, we couldn't initialize it. That's why the bank
name is empty here.
