## Development Servers
|
||
|
||
### Angular (Port 3000)
|
||
```bash
|
||
cd apps/angular
|
||
npm start
|
||
```
|
||
Used as reference implementation and baseline for visual regression testing.
|
||
|
||
### React (Port 3001)
|
||
```bash
|
||
cd apps/react
|
||
npm run dev
|
||
```
|
||
Test target for Cypress and comparison target for BackstopJS.
|
||
|
||
## Execution Flow for Tasks 56-59
|
||
|
||
### Task 56: Generate Angular Baseline
|
||
1. Start Angular on port 3000: `cd apps/angular && npm start`
|
||
2. Run baseline capture: `cd e2e && npm run backstop:reference`
|
||
3. Verify 12+ images in `bitmaps_reference/`
|
||
4. Commit baseline: `git add e2e/backstop/bitmaps_reference/ && git commit`
|
||
|
||
### Task 57: Compare React to Baseline
|
||
1. Start React on port 3001: `cd apps/react && npm run dev`
|
||
2. Run comparison: `cd e2e && npm run backstop:test`
|
||
3. Review HTML report: `e2e/backstop/html_report_react/index.html`
|
||
4. Document differences found
|
||
|
||
### Task 58: Fix Visual Differences
|
||
1. For each failed scenario in report:
|
||
- Identify React component/CSS
|
||
- Compare Angular vs React styles
|
||
- Update React SCSS to match
|
||
- Rerun test for that scenario
|
||
2. Iterate until all tests pass
|
||
|
||
### Task 59: Full Validation
|
||
1. Run Cypress: `npm run cypress:run`
|
||
2. Run final BackstopJS: `npm run backstop:test`
|
||
3. Generate validation report
|
||
4. Commit all results
|
||
|
||
## Required Data-TestID Attributes
|
||
|
||
The BackstopJS scenarios depend on these data-testid values being present in both Angular and React:
|
||
|
||
- `data-testid="page-loaded"` - Main page container
|
||
- `data-testid="board-page-loaded"` - Board page container
|
||
- `data-testid="schedule-page-loaded"` - Schedule page container
|
||
- `data-testid="flights-map-loaded"` - Flights map container
|
||
|
||
**Status:** Ready selectors defined in config, implementation status depends on Task 11-55 completion.
