foxhunt/trading_engine/tests/compliance_automated_reporting_tests.rs

//! Comprehensive tests for automated reporting compliance module
//!
//! Tests cover:
//! - Scheduled report generation (daily, weekly, monthly, quarterly)
//! - Report delivery mechanisms (email, SFTP, API)
//! - Regulatory deadline tracking (MiFID II, EMIR)
//! - Report template processing
//! - Transaction aggregation and summary generation
//!
//! Total tests: 25
//! Target coverage: 70-75% of automated_reporting.rs
