Test card
Also called: Test card number
A card number published by a payment provider to simulate payments in test mode.
Definition
Payment providers publish special card numbers that simulate outcomes like approved, declined or insufficient funds, without moving real money. Testers always use these on test environments, never real cards.
In practice
Stripe's 4242 4242 4242 4242 approves any test payment; other published numbers trigger a decline or a 3-D Secure challenge.
