Test Payments

Test Payments puts realistic payment and identity test data one right-click away. Right-click any editable field on a page, pick a value from the Test Payments menu, and it's inserted instantly — no more hunting through provider docs or keeping a scratch file of test card numbers. Built for developers and QA engineers who test checkout, payment, and signup flows. It ships with official sandbox test cards for a dozen major payment providers (including Stripe, Adyen, and Braintree), each with the expected test values, successful cards by brand, decline scenarios, and 3D Secure cards. It can also generate fresh fictional identity data — names, addresses, phones, emails, and company names — on demand using Chrome's built-in on-device AI, plus ready-made static names and addresses for US, UK, and AU. Private by design: no data collection, no tracking, no external servers. Built on Manifest V3 with minimal permissions — the extension only runs on a page when you click a menu item.
