eCommerce Testing

eCommerce testing covers the end-to-end customer journey from product discovery to post-purchase. Revenue is directly tied to functionality — a broken checkout flow is a quantifiable business loss, making thorough testing a commercial priority.

◈Key Points

Critical paths: product search → product detail → add to cart → checkout → payment → confirmation → fulfilment notification.
Payment gateway integration testing: test all payment methods, failure scenarios, and partial refunds.
Performance under peak load: Black Friday and sale events generate traffic spikes — load test for 10× normal volume.
Inventory management: simultaneous purchase by multiple users of the last item — race conditions are real.
Tax and shipping calculation accuracy: edge cases around international orders, tax exemptions, and discount stacking.

⚡ Expert Pro Tip

Always test payment failure recovery. The path from 'payment failed' back to a successful checkout is where users abandon most. It's under-tested and over-important.
