stripe-test-cards-and-webhooks

Overview

Stripe's test-mode is feature-complete: every API call works against test data, no real money moves. Per docs.stripe.com/testing, test keys (sk_test_* / pk_test_*) accept canonical test cards that deterministically produce success / decline / 3DS challenge.

When to use

• Tests for code that integrates Stripe.
• Verifying webhook handling.
• 3DS challenge flow tests per the 3DS flows reference in payment-flow-test-author (its payment-states reference).
