+## Test Quality Standards
+
+### Patterns Applied
+- **AAA Pattern:** Arrange, Act, Assert (100% compliance)
+- **Mocking:** Comprehensive API mocking via `setup.ts`
+- **Fixtures:** Shared test fixtures (mockUserToken, mockItems, etc.)
+- **Error Handling:** Realistic async scenarios and error cases
+- **Accessibility:** Semantic HTML and ARIA compliance checks
+- **Edge Cases:** Empty states, timeouts, validation failures
+
+### Code Quality
+- Proper cleanup with `beforeEach()` / `afterEach()`
+- Helper functions for render (reduce duplication)
+- Consistent naming conventions
+- Type-safe with TypeScript strict mode
+- Comments for complex test scenarios
