## Running the Tests

### Individual File
```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web

```

### All Page Tests
```bash
npm test src/__tests__/pages/
```

### With Coverage
```bash
npm test -- --coverage src/__tests__/pages/
```

## Expected Test Output

When run with a proper test environment:
- **183 test cases** should pass
- **6 test suites** should complete
- **Coverage:** Each page component should have >90% coverage
- **Runtime:** ~30-60 seconds for all tests

## Integration with Existing Tests

These page tests complement the existing test suite:
- **Component tests:** Unit tests for individual components
