qa-payment

Payment testing for Stripe, Adyen, PayPal and Braintree sandboxes: test cards, webhooks, subscription billing, refunds, chargebacks and 3DS flows. Includes a payment lifecycle state reference and a review agent (payment-flow-critic) that flags missing idempotency keys and other high-incident payment defects. Distinct from qa-compliance/pci-dss-control-test-author (PCI DSS scope and controls).

What it installs

Skills (4)

  • payment-flow-test-author

    Use when a payment integration needs refund, dispute or payment-webhook tests: a refund matrix (full, partial, over-refund) for Stripe, Adyen, PayPal and Braintree, chargebacks with card-network reason codes, and webhook replay through each gateway's simulator.

  • payment-gateway-sandboxes

    Use when code integrated with Adyen, PayPal or Braintree needs tests in sandbox mode: test credentials, sandbox URLs, deterministic test card numbers and each gateway's webhook simulator. For Stripe use stripe-test-cards-and-webhooks or stripe-subscription-billing-test-author.

  • stripe-subscription-billing-test-author

    Use when Stripe subscriptions or recurring billing need tests: trial to paid, proration on upgrade and downgrade, dunning on failed renewals, cancel and reactivate, and the subscription webhook events, using Stripe test clocks to skip through billing cycles without waiting.

  • stripe-test-cards-and-webhooks

    Use for any question or task about testing Stripe payments, including one webhook handler and checkout that fails for 3D Secure cards: test-mode keys, test cards for success, declines and 3D Secure, stripe listen to forward webhooks locally, stripe trigger fixtures, and Stripe-Signature verification

Subagents (1)

  • payment-flow-critic

    Use proactively whenever a PR touches payment integration code. Checks for missing idempotency keys on charges, unverified webhook signatures, card data in logs, unhandled 3DS requires_action states and double-charge races, with severity, fixes and a BLOCK or PASS verdict.
