Test Cases for a Payment Gateway: Complete Guide + Free Templates
A failed payment is never just a technical failure. It is the moment a customer loses confidence in your platform, abandons their purchase, and often does not return. Unlike most bugs, a payment failure has a direct and immediate cost. This guide gives you the test cases to prevent that. Below you will find over 50 test cases organised by type and filterable by category, guidance on using AI to speed up your test suite, and a pre-launch checklist you can work through before every release.
