/**
 * ⛔ DEPRECATED - January 2025
 * This test file has been deprecated and replaced by comprehensive E2E testing framework
 *
 * Reasons for deprecation:
 * - Tests old event creation/management forms that have been replaced
 * - Individual test files replaced by comprehensive test suites
 * - Page Object Model (POM) architecture provides better test organization
 * - Modern test framework with better error handling and reporting
 *
 * Replacement: test-master-trainer-e2e.js + test-comprehensive-validation.js
 * - Comprehensive E2E testing covering all event workflows
 * - Page Object Model for maintainable tests
 * - Better test organization and reporting
 * - Docker-based testing environment
 *
 * See: DEPRECATED-FILES.md for full migration details
