Web
|
|
|
|
## Status
|
|
IMPLEMENTED
|
|
|
|
## Description
|
|
Visual graph diff engine with split-view component for comparing two dependency/SBOM graphs side by side with change highlighting, diff computation, and synchronized navigation.
|
|
|
|
## Implementation Details
|
|
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/graph/`
|
|
- **Components**:
|
|
- `graph-canvas` (`src/Web/StellaOps.Web/src/app/features/graph/graph-canvas.component.ts`)
|
|
- `graph-explorer` (`src/Web/StellaOps.Web/src/app/features/graph/graph-explorer.component.ts`)
|
|
- `graph-filters` (`src/Web/StellaOps.Web/src/app/features/graph/graph-filters.component.ts`)
|
|
- `graph-hotkey-help` (`src/Web/StellaOps.Web/src/app/features/graph/graph-hotkey-help.component.ts`)
|
|
- `graph-overlays` (`src/Web/StellaOps.Web/src/app/features/graph/graph-overlays.component.ts`)
|
|
- `graph-side-panels` (`src/Web/StellaOps.Web/src/app/features/graph/graph-side-panels.component.ts`)
|
|
- **Services**:
|
|
- `graph-accessibility` (`src/Web/StellaOps.Web/src/app/features/graph/graph-accessibility.service.ts`)
|
|
- **Source**: Feature matrix scan

## E2E Test Plan
|
|
- **Setup**:
|
|
- [ ] Log in with a user that has appropriate permissions
|
|
- [ ] Navigate to `/graph`
|
|
- [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
|
|
- **Core verification**:
|
|
- [ ] Verify side-by-side comparison view renders correctly with two versions
|
|
- [ ] Verify additions, removals, and changes are visually highlighted
|
|
- [ ] Verify diff data matches the expected delta between versions
|
|
- **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)
