Baymard’s checkout usability research consistently shows that technical faults—mobile layout breaks, surprise fees, broken coupon fields—drive abandonment as much as design choices. Yet most SMB stores test manually once, then ship. AI QA automates exploratory testing on staging and production-safe sandboxes.

What customers usually find first

  • Add-to-cart fails on certain variants.
  • Tax or shipping shown incorrectly at checkout.
  • Collection links that 404 after a rename.
  • Payment success page missing order summary.
  • Hero images that cover the buy button on small phones.

How the QA agent works

It runs scripted and exploratory paths with desktop and mobile viewports: browse, filter, cart, discount, pay (test mode), account, returns. Visual diffs flag regressions after theme or copy edits. Critical findings block publish until resolved or explicitly waived.

Connect the pillars

QA pairs with the SEO agent (broken URLs hurt crawl budget) and with the agentic team (merchandising agents can trigger re-tests after bulk catalog imports).
