nit: payment_test_utils

[Moe, 2017/07/05 13:59:23]

Hmm :? I've received the opposite feedback in the past, which is to prefer
_util.h over _utils.h

[Mathieu, 2017/07/05 14:23:00]

From code search test_util does seem a little more prevalent, you're right
(perhaps a 60/40 split between the two). I was saying this because we have
autofill_test_utils and now having this as test_util feels weird. We should pick
one

[Eugene But (OOO till 7-30), 2017/07/05 14:47:31]

FWIW: _util is more prevalent than _utils

[Moe, 2017/07/05 16:01:46]

It makes sense to move toward what's more prevalent. Let's change the
autofill_test_utils to autofill_test_util in a separate CL.
