/**
 * Contact Import End-to-End Tests
 * 
 * This comprehensive test suite validates Time Safari's contact import functionality
 * across all supported import methods and edge cases. The tests ensure that users
 * can reliably import contacts through various mechanisms while maintaining data
 * integrity and providing appropriate feedback.
 * 
 * ## How the Contact Import Page Works
 * 
 * ### User Workflow
 * 1. **Entry Point**: Users can reach contact import through multiple paths:
 *    - Direct navigation to `/contact-import` with URL parameters
 *    - Pasting contact data in the contacts page input field
 *    - Manual entry via textarea on the import page
 * 
 * 2. **Data Processing**: The system parses contact data in multiple formats:
 *    - JSON arrays: `[{"did":"did:ethr:0x...","name":"Alice"}]`
 *    - Individual contact strings: `"did:ethr:0x..., Alice, publicKey"`
 *    - JWT tokens (future implementation)
 * 
 * 3. **Contact Analysis**: For each contact, the system:
 *    - Validates the DID format and required fields
 *    - Checks if the contact already exists in the database
 *    - Compares field values for existing contacts to detect differences
 *    - Categorizes contacts as "New" or "Existing"
 * 
 * 4. **UI Presentation**: The ContactImportView displays:
 *    - A list of all contacts with checkboxes for selection
 *    - Status indicators ("New" in green, "Existing" in orange)
 *    - Field comparison tables for existing contacts with differences
 *    - Visibility settings checkbox for activity sharing
 *    - Import button to execute the selected contacts
 * 
 * 5. **Import Process**: When users click "Import Selected Contacts":
 *    - Selected contacts are processed in batch
 *    - New contacts are added to the database
 *    - Existing contacts are updated with new field values
 *    - Success/error feedback is displayed
 *    - Users are redirected back to the contacts list
 * 
 * ### Page Structure and Components
 * 
 * **ContactImportView.vue**:
 * - **Header**: Back navigation and "Contact Import" title
 * - **Loading State**: Spinner while processing contact data
 * - **Visibility Settings**: Checkbox for making activity visible to imported contacts
 * - **Contact List**: Each contact displayed with:
 *   - Checkbox for selection
 *   - Contact name and DID
 *   - Status indicator (New/Existing)
 *   - Field comparison table for existing contacts
 * - **Import Button**: Executes the import process
 * - **Empty State**: Message when no contacts are found
 * 
 * **ContactInputForm Component** (in ContactsView):
 * - **Input Field**: Accepts contact data in various formats
 * - **Add Button**: Triggers contact processing
 * - **QR Scanner**: Alternative input method
 * - **Validation**: Real-time validation of input format
 * 
 * ### Data Flow
 * 
 * 1. **Input Processing**:
 *    ```typescript
 *    // Contact data can be provided as:
 *    const contactData = 'Paste this: [{"did":"did:ethr:0x...","name":"Alice"}]';
 *    // or individual format:
 *    const contactData = 'did:ethr:0x..., Alice, publicKey';
 *    ```
 * 
 * 2. **Contact Validation**:
 *    - DID format validation (must be valid DID)
 *    - Required field checking (name is optional but recommended)
 *    - Duplicate detection against existing contacts
 * 
 * 3. **Field Comparison**:
 *    - For existing contacts, compare all fields
 *    - Display differences in a table format
 *    - Allow users to see what will be updated
 * 
 * 4. **Batch Import**:
 *    - Process all selected contacts in a single transaction
 *    - Handle both new additions and updates
 *    - Maintain data integrity throughout the process
 * 
 * ### Error Handling
 * 
 * The system handles various error scenarios:
 * - **Invalid Data**: Malformed JSON, missing fields, wrong types
 * - **Network Issues**: Failed data retrieval from URLs
 * - **Database Errors**: Storage quota exceeded, connection issues
 * - **UI Errors**: Modal conflicts, alert dismissal failures
 * 
 * ### Performance Considerations
 * 
 * - **Large Contact Lists**: Efficient processing of 10+ contacts
 * - **Field Comparison**: Optimized comparison algorithms
 * - **Batch Operations**: Database transactions for multiple contacts
 * - **Memory Management**: Proper cleanup of temporary data
 * 
 * ## Test Coverage Overview
 * 
 * ### Import Methods Tested
 * 1. **Direct Contact Addition**: Single contact via contacts page input
 * 2. **Batch Import via Text**: Multiple contacts pasted into input field
 * 3. **URL Query Parameters**: Contact data passed via URL parameters
 * 4. **Manual Data Input**: Contact data entered via textarea
 * 5. **Selective Import**: Checkbox-based contact selection
 * 
 * ### Error Scenarios Validated
 * - Invalid JWT format detection and handling
 * - Malformed contact data validation
 * - Empty contact array handling
 * - Missing required fields detection
 * - Wrong data type handling
 * - Network error simulation
 * 
 * ### Performance and Reliability
 * - Large contact list import performance
 * - Alert dismissal reliability
 * - Modal dialog handling
 * - Duplicate contact detection
 * - State management and cleanup
 * 
 * ## Test Data Strategy
 * 
 * Each test uses unique contact data generated with timestamps and random
 * suffixes to prevent conflicts with existing database contacts. This ensures
 * test isolation and reliable results across multiple test runs.
 * 
 * ## Key Implementation Details
 * 
 * ### Performance Monitoring
 * The test suite includes a PerformanceMonitor class that tracks execution
 * times for critical operations, helping identify performance bottlenecks
 * and ensuring consistent test behavior across different environments.
 * 
 * ### Error Handling Patterns
 * Tests implement robust error handling for UI interactions, including:
 * - Modal dialog detection and dismissal
 * - Alert message verification
 * - Network error simulation
 * - Graceful degradation for failed operations
 * 
 * ### State Management
 * Each test maintains clean state through:
 * - Pre-test user import and contact cleanup
 * - Post-test contact cleanup
 * - Isolated test data generation
 * - Proper resource cleanup
 * 
 * ## Usage Examples
 * 
 * ### Basic Contact Import
 * ```typescript
 * // Navigate to contacts page
 * await page.goto('./contacts');
 * 
 * // Add contact via input field
 * await page.getByPlaceholder('URL or DID, Name, Public Key')
 *   .fill('did:ethr:0x123..., Alice Test');
 * 
 * // Submit and verify
 * await page.locator('button > svg.fa-plus').click();
 * await expect(page.locator('div[role="alert"] span:has-text("Success")'))
 *   .toBeVisible();
 * ```
 * 
 * ### Batch Contact Import
 * ```typescript
 * // Prepare contact data
 * const contactData = 'Paste this: [{"did":"did:ethr:0x123...","name":"Alice"}]';
 * 
 * // Navigate and input data
 * await page.goto('./contacts');
 * await page.getByPlaceholder('URL or DID, Name, Public Key').fill(contactData);
 * await page.locator('button > svg.fa-plus').click();
 * 
 * // Verify import page and import contacts
 * await expect(page.getByRole('heading', { name: 'Contact Import' })).toBeVisible();
 * await page.locator('button:has-text("Import Selected Contacts")').click();
 * ```
 * 
 * ## Test Architecture
 * 
 * ### PerformanceMonitor Class
 * Provides detailed timing information for test operations, helping identify
 * performance issues and ensuring consistent test behavior.
 * 
 * ### Test Data Generation
 * Creates unique contact data with timestamps and random suffixes to prevent
 * conflicts and ensure test isolation.
 * 
 * ### Error Simulation
 * Tests various error conditions including invalid data formats, network
 * failures, and malformed inputs to ensure robust error handling.
