//! ICMarkets FIX 4.4 Real Integration Validation Tests
//!
//! These tests validate the REAL ICMarkets FIX 4.4 integration by testing:
//! - TCP connection establishment to ICMarkets FIX endpoint
//! - FIX 4.4 protocol logon and session management
//! - Order submission, modification, and cancellation workflows
//! - Execution report processing and position tracking
//! - FIX sequence number management and error recovery
//!
//! NOTE: These tests are designed to gracefully handle connection failures
//! in CI environments while validating real broker integration functionality.
