## E2E Test Plan
|
|
- **Setup**:
|
|
- [ ] Log in with a user that has appropriate permissions
|
|
- [ ] Navigate to `/compare/:currentId`
|
|
- [ ] 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)
