Code Review

This pull request updates the default version of the Adyen Checkout service from 71 to 72 and updates the SDK generation log. The review feedback correctly points out that this version bump will cause test failures in spec/checkout_spec.rb because the test expectations still look for v71, and advises updating those tests to match the new default version.

[gemini-code-assist]

Updating DEFAULT_VERSION to 72 will cause test failures in spec/checkout_spec.rb because several test cases (such as those on lines 650 and 676) expect the URL version to be v71. Please update the corresponding test expectations in spec/checkout_spec.rb to use v72 to match this new default version.

focus: true is for filtering out tests during development (running a specific test). Removed this, seems to be a temporary marker from before that slipped in as the repo doesn't run tests with focus-filtering enabled, so it's inert.

For reference, if anyone looks back at this PR, rundown of the test changes:

• Fixed breaking tests (was quite straight-forward, just changing 71->72 in the endpoints)
• Added tests for new payments endpoint (update_session)
• While here:
  • Updated outdated mocks in tests (were still using old models)
  • Added tests for missing endpoints whose models were actually modified during the upgrade but were previously untested.

Regarding these extra changes:

• Outdated mocks:
  • POST /payments/{paymentPspReference}/amountUpdates — request + response mocks
  • POST /orders — request + response mocks
  • POST /orders/cancel — response mock (invalid resultCode enum value)
  • POST /payments/details — request + response mocks
  • POST /paymentMethods/balance — request + response mocks
  • POST /paymentLinks — response mock + status code corrected to 201
  • POST /paymentMethods — response mock
  • DELETE /storedPaymentMethods/{storedPaymentMethodId} — status code corrected to 204
• New (missing) tests -> note, I only added tests where models were changed via v72 but endpoints weren't already tested:
  • POST /payments — payments_api.payments
  • POST /payments/{paymentPspReference}/reversals — modifications_api.refund_or_cancel_payment
  • POST /cardDetails — payments_api.card_details
  • POST /donations — donations_api.donations
  • POST /donationCampaigns — donations_api.donation_campaigns
  • POST /paypal/updateOrder — utility_api.updates_order_for_paypal_express_checkout
  • POST /storedPaymentMethods — recurring_api.stored_payment_methods
