Overview

A silent failure in your payment gateway or shopping cart can go unnoticed for hours, costing your business thousands of pounds in abandoned checkouts and lost revenue.

Testing Strategies

• Sandbox Testing Modes: Use your payment gateway's staging or sandbox mode to execute test purchases following major platform or plugin updates.
• Multi-Device Checkout Audits: Verify that mobile, tablet, and desktop checkout workflows, including autofill fields and digital wallet integrations (Apple Pay/Google Pay), function without visual layout errors.
• Failed Payment Handling: Test how your system responds to declined cards or gateway timeouts to ensure customers receive clear, helpful error messages instead of blank loading screens.
