//! Smoke Tests - End-to-End System Validation
//!
//! Automated smoke tests to validate complete system functionality after deployment.
//! Tests are organized by category and can run selectively based on service availability.
//!
//! ## Test Categories
//! - Infrastructure Health (PostgreSQL, Redis, Vault, InfluxDB)
//! - Service Health (API Gateway, Trading, Backtesting, ML Training)
//! - Authentication Flow (JWT, MFA, Session Management)
//! - Basic Order Flow (Submit, Query, Cancel, Positions)
//! - Market Data (Streaming, Historical Queries)
//! - ML Inference (Predictions, Feature Engineering)
//! - Compliance (Audit Logs, Best Execution, Risk Checks)
//! - Metrics and Monitoring (Prometheus, Grafana)
//!
//! ## Usage
//! ```bash
//! # Run all smoke tests
//! cargo test --test smoke_tests
//!
//! # Run specific category
//! cargo test --test smoke_tests infrastructure_health
//! cargo test --test smoke_tests service_health
//! cargo test --test smoke_tests basic_order_flow
//!
//! # Run with logging
//! RUST_LOG=debug cargo test --test smoke_tests -- --nocapture
//! ```
