The test store
AisleRun's own labelled fixture store, its four versions and the seeded defect.
The test store is a small storefront AisleRun built for itself at https://aislerun-fixtures.vercel.app. It looks and behaves like a Shopify product page, and every page says in its footer that it's a test fixture. It's the only store AisleRun is authorized to test today.
The four versions
Each version lives at its own fixed path, so a result always names exactly what it tested.
| Version | What it does | Expected result |
|---|---|---|
fixture-healthy-v1 |
Normal product, cart and checkout | Pass on both viewports |
fixture-mobile-cart-broken-v1 |
Add to cart throws an error below 750 px wide | Mobile fails, desktop passes |
fixture-fixed-v2 |
The one-line repair of that bug | Pass on both viewports |
fixture-bot-check-v1 |
A human-verification wall instead of the product | Inconclusive on both viewports |
Product pages are at /v/<version>/products/cup, and the cart and checkout pages follow the same pattern.
The seeded defect
On the broken version, the Add to cart handler looks for a cart drawer that doesn't exist on narrow screens. It throws before the cart is saved, so nothing happens when a phone shopper presses the button. The fix makes both screen sizes use the same drawer.
- var isMobile = window.matchMedia("(max-width: 749px)").matches;
- return document.getElementById(isMobile ? "CartDrawer-mobile" : "CartDrawer");
+ return document.getElementById("CartDrawer");
The browser console shows the real error: Cannot set properties of null (setting 'hidden'). AisleRun reports it as a possible cause, not a diagnosis.
How the store tracks the cart
The cart lives in the browser's local storage, keyed by version. The header shows a cart count and the cart drawer lists each line, which gives AisleRun its two cart signals. The checkout page collects nothing and has no submit button.
