## Module

Web
|

|
|
## Status

|
VERIFIED
|
|
|
|
## Description
|
|
Tabular SBOM component-change diff view with change-type filter chips, debounced search, multi-column sorting, row selection with bulk actions, pagination, clipboard actions, and CSV export for lineage comparisons.
|
|
|
|
## Implementation Details
|
|
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/lineage/components/node-diff-table/`
|
|
- **Primary component**:
|
|
- `diff-table.component.ts`
|
|
- `diff-table.component.html`
|
|
- `diff-table.component.scss`
|
|
- `models/diff-table.models.ts`
|
|
- **Service dependency**:
|
|
- `src/Web/StellaOps.Web/src/app/features/lineage/services/lineage-graph.service.ts`
|
|
- **Behavioral tests**:
|
|
- `src/Web/StellaOps.Web/src/tests/lineage/node-diff-table-component.spec.ts`
|
|
|
|
## E2E Test Plan
|
|
- **Setup**:
|
|
- [ ] Log in with a user that has appropriate permissions
|
|
- [ ] Navigate to lineage comparison workflow hosting the node diff table
|
|
- [ ] Ensure comparison data exists (added/removed/changed components)
|
|
- **Core verification**:
|
|
- [ ] Verify component rows render and sort deterministically
|
|
- [ ] Verify search is debounced and filter chips (including both-changed) work
|
|
- [ ] Verify bulk actions, pagination, and API-input based diff fetch behavior
|
|
- **Edge cases**:
|
|
- [ ] Verify graceful handling when backend API is unavailable (error state)
|
|
- [ ] Verify responsive layout at different viewport sizes
|
|
- [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
|
|
