with WebPageValidator(headless=True) as validator:
    result = validator.validate_url('http://127.0.0.1:5000')

    # Check for JavaScript errors
    if result.console_errors:
        print(f"[ERROR] Found {len(result.console_errors)} console errors")
        for error in result.console_errors:
            print(f"  - {error.message}")
            print(f"    Line: {error.line}, Source: {error.source}")

    # Check for network failures
    if result.network_errors:
        print(f"[ERROR] Found {len(result.network_errors)} network errors")

    # Verify performance
    if result.load_time > 5.0:
