Test your payments integrations end-to-end with the new test suite for Google Pay- Google Developers Blog

What this post added

Introduced an upgraded test suite for the Google Pay API in TEST mode, featuring PSP test cards from major payment processors (Stripe, Adyen, Braintree, WorldPay, Checkout.com). This enables end-to-end testing of payment flows, including diverse outcomes like fraud, declines, and insufficient funds. The suite supports test automation with Android testing frameworks (UIAutomator, Espresso) and integration into CI/CD pipelines. Web support is planned for later.
