Pro UI test design
Practice a senior-style answer for checkout flows, including pricing, promos, payment failures, duplicate prevention, accessibility, backend contracts, and support signals.
Pro trainer
The checkout flow includes cart review, shipping and billing forms, promo codes, tax and shipping totals, payment method selection, payment provider states, and order confirmation.
How to use this trainer
No backend or external AI is called. Your answer is scored locally against a structured QA checklist.
Cover the happy path, validation, payment failure states, duplicate prevention, backend contracts, UX/accessibility, and observability.
Tip: a stronger answer usually mixes happy path, negative cases, state changes, data, backend, UX, accessibility, and risk.
