/**
 * Test Mock Factory - Consolidated Mocking Utilities
 *
 * This factory provides centralized mocking for external dependencies
 * to eliminate duplication across test setup files.
 *
 * Key Features:
 * - Single source of truth for all test mocks
 * - Consistent mock configuration across test files
 * - Easy to extend with new mock patterns
 * - Memory-efficient test environment setup
 * - Singleton pattern prevents duplicate mock creation
