  Telr test mode is toggled per transaction (test=1 on the legacy gateway,
  "test": true on the REST Payments API) rather than via separate test keys. Test
  cards work only in test mode and never for live transactions. All values below
  are published verbatim by Telr; none are invented.
test_mode:
  legacy_gateway: "order.test = 1 (0 = live, 1 = test)"
  remote: "tran.test = 1"
  rest_payments: '"test": true'
cvv_rules:
  authorised: "123 (American Express: 1234)"
  declined: "any other CVV declines"
  on_hold: "999 places the transaction on hold"
  simulate_response_code: >-
    Pad the desired response code to three digits with a leading zero and pass it
    as the CVV. Example: CVV 041 simulates code 41 (Insufficient funds). See
    errors/telr-decline-codes.yml.
