missing canaries more likely?
insufficient tests that dont assert on the right things?
the existence of a test doesnt mean it catches the right thing
based on the description, id bet the COE action item will be to do a migration that enforces units are passed at the billing service level
theres no good reason for the billing service to make up its own units.

Technically, there could be a test. It could just be wrong!

why would a test setting unit to Bytes fail and not MB, KB, or GB, and so on? That's like trying create a unit test for email opt-in, both true and false are valid values. It's up to the user to select the right one.
