braintree-test-cards

Overview

Per developer.paypal.com/braintree/docs/reference/general/testing, the Braintree sandbox accepts the same API as production with deterministic test-card responses.

The notable distinction: Braintree's Transaction state machine includes an explicit submitted_for_settlement → settled transition with simulated settlement in sandbox.

When to use

• Tests for code using Braintree.
• Drop-in / Hosted Fields client-side flow tests.
• 3DS tests per 3ds-test-flow-reference.
