The selected socks reached the cart. The drawer opened on live, but stayed closed on the draft.

Fictional store and sample evidence.
This is not a real store scan.
The item is in the cart. The drawer stayed closed.
After Add to cart, the drawer opens and shows the selected variant.
The item was added to the cart, but the drawer remained closed.
Share the report or copy this issue brief into a developer task or AI coding conversation, then recheck after the fix.
The item reached the cart, so check whether the drawer’s open handler runs afterward. Review any browser errors from that action. This is a possible cause to investigate, not a confirmed diagnosis.
Reproduce: Open PurpleFox socks → select Cream / M → Add to cart → check the drawer → open the cart page to confirm the item. The cause has not been determined.
Verify the fix: Rerun the same product and variant on desktop and mobile. Confirm the drawer opens with the correct item and quantity, and checkout entry remains reachable.
Outside this report’s coverage: Payment completion, subscriptions, other products, and other markets were not tested.

Questions before you start.
What can I test with PurpleFox?
Test Shopify draft themes, preview links, or individual storefront URLs. Compare pages against your live store before publishing, or check your live storefront after launch. Choose the pages and shopping flows that matter to your store.
Which shopping interactions are checked?
Automated functional tests cover variant selection, Add to Cart, quantity changes, cart removal, pricing, and checkout handoff. Checks run on desktop and mobile without placing orders or taking payments.
What visual issues can PurpleFox spot?
Screenshot comparisons help detect broken layouts, overlapping elements, missing images, clipped content, and unexpected visual changes on desktop and mobile. Review flagged differences and approve intentional design changes.
What comes in an issue report?
Reports include screenshots, affected pages, severity, device information, and steps to reproduce the problem. Share the report with your developer, agency, or team, and use scan history to track issues through resolution.
How does AI help me fix an issue?
AI turns technical findings into easy-to-understand explanations and copyable fix instructions for your developer or AI coding assistant. Fix briefs include the evidence and reproduction steps your team needs to investigate. Suggested causes still need to be confirmed, and you can rerun checks after a fix.
Will it monitor my live store too?
Yes. Schedule automatic storefront checks and run checks after theme publication. Notifications flag potential problems that appear after launch, so your team can investigate even after a successful release.
How do I keep intentional changes from becoming noise?
Approve intentional design changes, ignore irrelevant findings, and track open or resolved issues. Smart alert handling helps reduce duplicate notifications so your team can focus on the problems that need attention.
Does this work with AI-generated changes?
PurpleFox tests selected storefront flows whether a change came from AI, a developer, or an agency. AI explanations and developer-ready fix briefs help your team understand and act on the findings.
Does a passing report mean my whole store is safe?
A pass applies to the checks completed in that report. It does not cover every product, app, market, device, or business rule.
Will PurpleFox change my theme or place an order?
PurpleFox checks storefront behavior without editing theme code, placing orders, or taking payments. Shopping-flow checks may create test carts and reach checkout entry.
Does it work with every theme or subscription app?
We support selected theme and cart configurations. We will confirm compatibility during setup; subscriptions and complex bundles are outside the initial scope.
How do I get started?
Select Get started and tell us which draft theme, preview link, or storefront pages you want to check or monitor. We’ll confirm support for your theme and cart setup, help you choose the scope, and guide you through your first run.
