//! # Protocol Module Tests
//!
//! This module contains comprehensive tests for the Ri protocol system,
//! covering protocol configuration, frame parsing, and protocol state management.
//!
//! ## Test Coverage
//!
//! - **RiProtocolConfig**: Tests for configuration creation with custom settings
//! - **RiProtocolFrameType**: Tests for frame type enum variants and conversions
//! - **RiProtocolState**: Tests for protocol state transitions and initialization
//! - **RiProtocolStats**: Tests for statistics tracking and cloning
//! - **RiProtocolHealth**: Tests for health status enum variants
