foxhunt/tests/test_common/database_helper.rs

//! Database Test Helper for Foxhunt HFT System
//!
//! Consolidates database connection logic across 22+ test files to eliminate duplication
//! and provide consistent database setup/teardown functionality.
//!
//! This module provides:
//! - get_test_database_pool() - Centralized PostgreSQL pool creation
//! - setup_test_database() - Test database initialization and setup
//! - teardown_test_database() - Test data cleanup and connection closure
//! - Test data creation and management utilities
//! - Consistent database configuration across all tests
