E-commerce platforms rely on tightly connected systems such as product discovery, pricing, cart, checkout, payments, inventory, fulfillment, and returns. A failure at any point directly impacts revenue and customer trust.

Traditional testing approaches depend on manual scripts and isolated endpoint checks. These methods struggle to validate real shopping journeys and complex scenarios like discounts, taxes, partial payments, refunds, and inventory changes. During traffic spikes and promotions, gaps in coverage often surface as production issues, abandoned carts, and lost sales.
