description: >-
  Genome's test surface. There is no sandbox HOSTNAME and no test-mode key — test traffic is separated
  from live traffic by the CURRENCY on the request. Every value below is published verbatim by Genome.
model:
  type: currency-discriminated
  host: https://api.genome.eu (the production host; there is no separate sandbox host)
  discriminator_field: currency
  discriminator_value: XTS
  rationale: >-
    XTS is the ISO 4217 code reserved for testing. Genome states that test payments in XTS work even
    after a merchant account is approved and LIVE.
  key_prefixes: none
  test_clock: not offered
  risk_note: >-
    Because the test/live boundary is a payload field on the production host rather than a separate
    credential or endpoint, a wrong currency value is a real-money mistake. There is no fail-safe: the
    same merchant_account and merchant_password process both.
hosted_payment_page:
  test_mode: >-
    A payment page can be exercised in Test mode from the merchant dashboard before activation. Genome
    states that real transactions are only processed on an ACTIVATED payment page, which makes
    activation the explicit go-live gate.

test_cards:
  note: >-
    Published by Genome. These cards support the XTS currency only. CVV is any 3 random digits; expiry
    is any month 01-12 with a year of 2020 or later.
  cards:
  - brand: Visa
    flow: 2D
    number: '4111111111111111'
    cvv: any 3 digits
    expiry: MM 01-12 / YYYY 2020 or greater
  - brand: Mastercard
    flow: 2D
    number: '5555555555554444'
    cvv: any 3 digits
    expiry: MM 01-12 / YYYY 2020 or greater
  - brand: Visa
    flow: 3D Secure
    number: '4012000300001003'
    cvv: any 3 digits
    expiry: MM 01-12 / YYYY 2020 or greater
  - brand: Mastercard
    flow: 3D Secure
    number: '5191330000004415'

  steps:
  - Sign up at https://my.genome.eu
  - Send the list of transaction types your business model needs to support@genome.eu
  - Test every one of those transaction types in XTS
  - Send the references of the test transactions to support@genome.eu to close out test integration
  - Genome's integration team activates the account
  - Implement production credentials
  - Re-test production integration across all transaction types
  self_service: false
  note: >-
    Test access is not self-service. Two of the seven steps require a human at Genome to read an email
    and act, so an agent cannot get from signup to a working test call without a person in the loop.
fixtures:
  triggers: none published
  simulated_declines: >-
    Genome publishes no magic amounts or card numbers that force a specific decline code, so the
    137-code error registry cannot be exercised deterministically in test.
  test_ibans: none published
  vop_test_values: >-
    The Verification of Payee documentation shows a worked example against DE52100400000371301300 but
    does not designate it as a reserved test value.
gaps:
- No separate sandbox host or test key prefix.
- No fixtures or triggers to force specific decline codes.
- No test clock or time simulation for the 7-day authorization window.
- No published test data for the SEPA Payout, Query on Demand or Verification of Payee surfaces.
