Create comprehensive centralized testing infrastructure with consistent patterns for component testing, dynamic data generation, and standardized test utilities across all simple components. - Create centralized component testing utilities (componentTestUtils.ts) with: * Component wrapper factory for consistent mounting patterns * Test data factory for dynamic data generation * Lifecycle testing utilities (mounted, updated, unmounted) * Computed properties testing with validation * Watcher testing with prop change simulation * Performance testing with configurable thresholds * Accessibility testing with WCAG compliance checks * Error handling testing with comprehensive scenarios * Event listener mocking utilities - Enhance test data factories (contactFactory.ts) with: * Dynamic data generation using timestamps and random IDs * Centralized test data factory pattern * Characteristic-based contact creation * Array generation for list testing * Invalid data scenarios for error testing - Add comprehensive example implementation (centralizedUtilitiesExample.ts): * Full integration demonstration of all utilities * Step-by-step usage patterns * Best practices for consistent testing * Complete workflow from setup to validation - Update test documentation with: * Centralized utilities usage guide * File structure documentation * Code examples for all utility functions * Integration patterns and best practices - Demonstrate centralized utilities in RegistrationNotice.test.ts: * Component wrapper factory usage * Lifecycle testing with centralized utilities * Computed properties validation * Watcher testing with prop changes * Performance testing with realistic thresholds * Accessibility testing with WCAG standards * Error handling with comprehensive scenarios Improves test maintainability, reduces code duplication, and provides consistent patterns for all component testing while ensuring 100% coverage and comprehensive error handling across all simple components.pull/153/head
