Test cards for Cypress

Fill a Stripe (or any) payment form in a Cypress end-to-end test with a known test card so the run is deterministic.

Example

Cypress · js

// cypress/e2e/checkout.cy.js
const TEST_CARD = "4242 4242 4242 4242"; // Visa, succeeds in test mode

it("completes checkout", () => {
  cy.visit("/checkout");
  // Stripe mounts the card field in an iframe:
  cy.get("iframe").its("0.contentDocument.body").find('[name="cardnumber"]')
    .type(TEST_CARD);
  cy.get('[name="exp-date"]').type("12 / 34");
  cy.get('[name="cvc"]').type("123");
  cy.contains("Pay").click();
  cy.contains("Payment succeeded");
});

Test card numbers

The standard Stripe test numbers — successes and declines you can wire into your Cypress suite.

`4000 0000 0000 9995`	Visa	any 3 digits	Declined: insufficient_funds.
`4000 0000 0000 9987`	Visa	any 3 digits	Declined: lost_card.

`4100 0000 0000 0019`	Visa	any 3 digits	Declined: flagged as fraudulent (Radar).

Use any future expiry date (e.g. 12 / 34) and any postal code. Behaviors shown are for Stripe’s test mode; other processors publish their own test numbers. These cards are non-functional fixtures — they will be declined in production.
