test: add comprehensive tests for all Epic 1 stories
Story 1.2: Database Layer - Test database client creation, connection, ping, and close - Test connection pooling configuration - Tests skip if database is not available (short mode) Story 1.3: Health Monitoring and Metrics - Test health registry registration and checking - Test database health checker - Test liveness and readiness checks - Test metrics creation, middleware, and handler - Test Prometheus metrics endpoint Story 1.4: Error Handling and Error Bus - Test channel-based error bus creation - Test error publishing with context - Test nil error handling - Test channel full scenario - Test graceful shutdown - Fix Close() method to handle multiple calls safely Story 1.5: HTTP Server and Middleware - Test server creation with all middleware - Test request ID middleware - Test logging middleware - Test panic recovery middleware - Test CORS middleware - Test timeout middleware - Test health and metrics endpoints - Test server shutdown Story 1.6: OpenTelemetry Tracing - Test tracer initialization (enabled/disabled) - Test development and production modes - Test OTLP exporter configuration - Test graceful shutdown - Test no-op tracer provider All tests follow Go testing best practices: - Table-driven tests where appropriate - Parallel execution - Proper mocking of interfaces - Skip tests requiring external dependencies in short mode
