Add comprehensive test suite for current implementation
- Add tests for internal/config package (90.9% coverage) - Test all viperConfig getter methods - Test LoadConfig with default and environment-specific configs - Test error handling for missing config files - Add tests for internal/di package (88.1% coverage) - Test Container lifecycle (NewContainer, Start, Stop) - Test providers (ProvideConfig, ProvideLogger, CoreModule) - Test lifecycle hooks registration - Include mock implementations for testing - Add tests for internal/logger package (96.5% coverage) - Test zapLogger with JSON and console formats - Test all logging levels and methods - Test middleware (RequestIDMiddleware, LoggingMiddleware) - Test context helper functions - Include benchmark tests - Update CI workflow to skip tests when no test files exist - Add conditional test execution based on test file presence - Add timeout for test execution - Verify build when no tests are present All tests follow Go best practices with table-driven patterns, parallel execution where safe, and comprehensive coverage.
