Functional Testing for Custom Payment

I have a project that relies on a non-standard payment solution—something other than the usual credit cards, PayPal, or bank transfers—and I need to be absolutely sure the integration works seamlessly before we go live. Your task is to run thorough functional tests on this “other” payment gateway, confirming that every user flow (initiation, authorization, capture, refund, and error handling) behaves exactly as expected.


Once I have the test report and we confirm all critical paths pass, the job is done. Let’s make sure this payment flow is rock-solid.
