Why would you want to mark and ID verification test as expired?
The main reason is to enable a client of yours to re-run and ID test. If a client has done the test which is 'valid', we don't ask the client to redo this test if, for example, you ask the same client to run a different onboarding workflow (perhaps in a different capacity, for example, as a director of a different company). In that situation the workflow will check that the ID test has already been done for that client so it can be skipped. You save money, the client saves time.
