cvv test cases

A CVV test case is a documented pair of input and expected result used to prove that a checkout form, payment gateway integration, or tokenization flow validates the card verification value correctly. This library collects the cases QA teams actually run: 3-digit CVV2, 4-digit Amex CID, blank and malformed inputs, and the boundary conditions that quietly break naive validation. Every case is built around publicly documented sandbox card numbers, so no live cardholder data is ever involved.

Key Features

• 40+ documented test cases, each with input, expected result, gateway response code, and expected on-screen message
• Coverage for Visa, Mastercard, Discover, and JCB 3-digit CVV2 alongside American Express 4-digit CID
• Negative cases for blank fields, alphabetic input, whitespace, leading zeros, over-length strings, and non-ASCII digits
• Equivalence partitioning and boundary value notes so you can extend the set to your own form rules
• Sandbox card numbers sourced from publicly published gateway documentation
• Delivered in CSV and XLSX for direct import into TestRail, Zephyr, Jira, or a plain spreadsheet
• Change log tied to current PCI DSS wording and OWASP input validation guidance

The pack ships as an 18-page PDF plus two data files, so it works whether your team lives in a test management tool or a shared sheet. Cases are written to be gateway-agnostic: each row lists the expected behavior in plain language and, separately, the typical decline or error code that sandbox environments such as Stripe, Adyen, Braintree, and Authorize.net return. Nothing requires live credentials, and each case states its precondition, so a tester can run the full suite against a fresh sandbox in under an hour.

Access is instant — a download link is issued as soon as checkout completes, and the files stay available in your account for repeat downloads. If the pack does not fit your stack, request a refund within 30 days and it is processed without questions; updates to the library are included at no extra cost.

Are CVV test cases safe to run with real cards?

No. Run them only against sandbox or test-mode credentials using published test card numbers. Storing or transmitting real CVV values after authorization is prohibited under PCI DSS.

Which payment gateways do these cases work with?

Any gateway with a documented test mode. Expected results are written generically, with typical error codes noted for the major processors so you can map them to your own integration.

Do the cases cover 4-digit verification codes?

Yes. American Express CID uses four digits, and the suite includes positive, negative, and truncation cases for both the 3-digit and 4-digit formats.
