//! Bitfinex WebSocket live integration test.
//!
//! Tests:
//! - `bitfinex_ticker_two_symbols_receive_events` — Ticker for tBTCUSD + tETHUSD
//! - `bitfinex_liq_global_subscribe_and_receive` — liq:global status channel (liquidations)
//!
//! Verifies:
//! - chanId integer routing works (acks populate the map, data dispatches correctly)
//! - per-symbol topic key extraction works for two concurrent subscriptions
//! - status channel key-based chanId mapping works for liq:global
//! - symbol field is correctly populated in emitted StreamEvents
//! - application-level ping keeps the connection alive (20 s interval)
//!
//! Run with:
//!   cargo test --test bitfinex_ws_live -- --nocapture --ignored
