 ### Shop Page Integration Tests
-**Status:** Follow-up
+**Status:** Complete
 
-Home, product detail, and cart pages have no LiveView integration tests. Collection and content pages are well-covered (16 and 10 tests respectively). Priority order by logic complexity:
+All shop pages now have LiveView integration tests (612 total):
 
-1. **Product detail page** — variant selection, add-to-cart, gallery, breadcrumb
-2. **Cart page** — cart items, quantity changes, order summary, checkout link
-3. **Home page** — hero section, featured products, category nav (mostly presentational)
+- **Product detail page** (15 tests) — rendering, breadcrumbs, variant selection, price updates, add-to-cart, related products, fallback for unknown IDs
+- **Cart page** (10 tests) — empty state, item display with DB fixtures, order summary, increment/decrement, remove, checkout button
+- **Home page** (12 tests) — hero section, category nav, featured products, image+text section, navigation links
+- **Collection page** (16 tests, pre-existing) — category filtering, sorting, URL params
+- **Content pages** (10 tests, pre-existing) — about, delivery, privacy, terms
 
 ### Page Editor
 **Status:** Future (Tier 4)
