## E2E Test Plan
|
|
- **Setup**:
|
|
- [ ] Log in with a user that has appropriate permissions
|
|
- [ ] Navigate to `/lineage`
|
|
- [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
|
|
- **Core verification**:
|
|
- [ ] Verify the component renders correctly with sample data
|
|
- [ ] Verify interactive elements respond to user input
|
|
- [ ] Verify data is fetched and displayed from the correct API endpoints
|
|
- **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)
|
|
|
