//! Comprehensive test suite for TLI system

//! This module organizes and provides access to all test suites including:
//! - Unit tests for individual components
//! - Integration tests for end-to-end workflows
//! - Performance tests for latency and throughput validation
//! - Property-based tests for comprehensive edge case coverage
//! - Continuous monitoring infrastructure
