/**
 * Contact Management and Gift Recording Test Suite
 * 
 * This test suite verifies the contact management and gift recording functionality 
 * of the application. It includes tests for adding contacts, recording gifts, 
 * and confirming gifts.
 * 
 * Key Components:
 * 
 * 1. Constants
 *    - ALERT_TIMEOUT: For alert-related operations (5000ms)
 *    - NETWORK_TIMEOUT: For network operations (10000ms)
 *    - ANIMATION_TIMEOUT: For animation completion (1000ms)
 * 
 * 2. Main Test Cases
 *    - "Add contact, record gift, confirm gift"
 *      Tests complete flow of adding contact and managing gifts
 *    - "Without being registered, add contacts without registration"
 *      Verifies contact addition without registration
 *    - "Add contact, copy details, delete, and import"
 *      Tests contact import/export functionality
 * 
 * 3. Helper Functions
 *    - generateRandomString: Creates unique test identifiers
 *    - dismissAlertWithRetry: Handles alert dismissal with retry logic
 *    - recordGift: Encapsulates gift recording workflow
 *    - confirmGift: Manages gift confirmation process
 * 
 * Best Practices:
 * - Comprehensive error handling with try-catch blocks
 * - Random test data generation
 * - Consistent verification steps
 * - Page object patterns for maintainability
 * - Debug logging support
 * - Cross-browser compatibility considerations
 *
