## Summary
Lays the test foundation for the two open assets-testing issues — Phase
1 (fixtures + page object) and Phase 2 (unit tests). Phase 3/4 (the
actual E2E specs) follow in stacked PRs.
## Changes
- **What**: 27 new unit tests covering `useMediaAssetFiltering`,
`MediaAssetFilterMenu`, and `MediaAssetSettingsMenu`; reusable
Playwright fixture factories for diverse media kinds and execution-time
specs; new locators + helpers on `AssetsSidebarTab` for the filter menu
and longest/fastest sort options. No production code touched.
- **Breaking**: none
### New files
- `src/platform/assets/composables/useMediaAssetFiltering.test.ts` — 11
cases: single/multi-OR media-type filter, `'3D'` → `'3d'` filename
normalization, exclusion of unsupported kinds, all four sort modes,
`created_at` fallback when `user_metadata.create_time` is absent,
filter+sort composition.
- `src/platform/assets/components/MediaAssetFilterMenu.test.ts` — 6
cases: checkbox rendering, prop-driven `aria-checked`, click toggling
(add/remove/append), keyboard activation (Enter/Space).
- `src/platform/assets/components/MediaAssetSettingsMenu.test.ts` — 10
cases: view-mode v-model, `showSortOptions` and `showGenerationTimeSort`
visibility gates, `v-model:sortBy` round-trip for
newest/oldest/longest/fastest.
### Extended files
- `browser_tests/fixtures/helpers/AssetsHelper.ts` — added
`MediaKindFixture` type, optional `mediaKind` shorthand on
`createMockJob` (sets both filename extension and
`preview_output.mediaType`), plus `createMixedMediaJobs(kinds)` and
`createJobsWithExecutionTimes(specs)` factories for unambiguous
filter/sort assertions.
- `browser_tests/fixtures/components/SidebarTab.ts` — added
`filterButton`, per-type checkbox locators
(`filterImage/Video/Audio/3DCheckbox`), `sortLongestFirst`,
`sortFastestFirst`, plus `openFilterMenu()`, `filterCheckbox(kind)`,
`toggleMediaTypeFilter(kind)`, and `getAssetCardOrder()` helpers.
## Review Focus
- **Naming of `MediaKindFixture` values** — `'images'` is plural to
match existing API conventions emitted by the backend /
`useMediaAssetGalleryStore`; `'video' | 'audio' | '3D'` follow the
singular `MediaKind` type. Open to renaming if a unified shape is
preferred.
- **Filter button locator strategy** — `MediaAssetFilterButton` has no
`aria-label`, so the page object targets it via the
`icon-[lucide--list-filter]` class. Happy to add a `data-testid` or
`aria-label` to the source component if reviewers prefer a more durable
hook (would be a one-line source change in a follow-up).
## Follow-up PRs
- Phase 3 (E2E for media-type filter) → closes#10780
- Phase 4 (E2E for asset sort) → closes#10779
Both are stacked on this branch and can be reviewed/merged in either
order once this lands.
