//! 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 use std::collections::HashMap; use chrono::Utc; // CANONICAL TYPE IMPORTS - Use core types throughout // All Decimal operations use rust_decimal::Decimal use ::rust_decimal::Decimal; use sqlx::{PgPool, Row}; use std::time::Duration; use tokio::time::timeout; use uuid::Uuid; /// Database test configuration #[derive(Debug, Clone)] /// DatabaseTestConfig component. pub struct DatabaseTestConfig { pub postgres_url: String, pub influxdb_url: String, pub redis_url: String, pub test_timeout_secs: u64, pub pool_max_size: u32, pub pool_timeout_secs: u64, pub cleanup_on_drop: bool, } impl Default for DatabaseTestConfig { fn default() -> Self { // Load test environment variables crate::load_test_env(); let db_host = std::env::var("DATABASE_HOST") .or_else(|_| std::env::var("POSTGRES_HOST")) .unwrap_or_else(|_| "localhost".to_string()); Self { postgres_url: std::env::var("TEST_DATABASE_URL").unwrap_or_else(|_| { format!( "postgresql://foxhunt_test:test_password@{}:5433/foxhunt_test", db_host ) }), influxdb_url: std::env::var("TEST_INFLUXDB_URL") .unwrap_or_else(|_| format!("http://{}:8086", db_host)), redis_url: std::env::var("TEST_REDIS_URL") .unwrap_or_else(|_| format!("redis://{}:6379/1", db_host)), test_timeout_secs: 30, pool_max_size: 5, pool_timeout_secs: 10, cleanup_on_drop: true, } } } impl DatabaseTestConfig { /// Create configuration for testing with Docker Compose pub fn docker_compose() -> Self { let postgres_host = std::env::var("POSTGRES_HOST") .or_else(|_| std::env::var("DATABASE_HOST")) .unwrap_or_else(|_| "localhost".to_string()); let influx_host = std::env::var("INFLUXDB_HOST").unwrap_or_else(|_| "localhost".to_string()); let postgres_user = std::env::var("POSTGRES_USER").unwrap_or_else(|_| "foxhunt".to_string()); let postgres_password = std::env::var("POSTGRES_PASSWORD") .or_else(|_| std::env::var("TEST_DB_PASSWORD")) .unwrap_or_else(|_| "test_password".to_string()); // Default for testing let postgres_db = std::env::var("POSTGRES_DB").unwrap_or_else(|_| "foxhunt_dev".to_string()); Self { postgres_url: format!( "postgresql://{}:{}@{}:5432/{}", postgres_user, postgres_password, postgres_host, postgres_db ), influxdb_url: format!("http://{}:8086", influx_host), redis_url: std::env::var("REDIS_URL") .unwrap_or_else(|_| format!("redis://{}:6379", postgres_host)), ..Default::default() } } /// Create configuration for `CI`/`CD` environments pub fn ci_environment() -> Self { Self { test_timeout_secs: 10, // Shorter timeouts for CI pool_max_size: 2, // Smaller pools for CI pool_timeout_secs: 5, ..Self::docker_compose() } } /// Validate the configuration pub fn validate(&self) -> Result<(), String> { if self.postgres_url.is_empty() { return Err("PostgreSQL URL cannot be empty".to_string()); } if !self.postgres_url.starts_with("postgresql://") { return Err(format!( "Invalid PostgreSQL URL format: {}", self.postgres_url )); } if self.pool_max_size == 0 { return Err("Pool max size must be greater than 0".to_string()); } Ok(()) } } /// Database test pool with cleanup tracking #[derive(Debug)] pub struct DatabaseTestPool { pub pool: PgPool, pub config: DatabaseTestConfig, pub test_session_id: Uuid, pub created_test_ids: HashMap>, } impl DatabaseTestPool { /// Create a new test pool with the given configuration pub async fn new(config: DatabaseTestConfig) -> Result { use tracing::{debug, error}; let test_session_id = Uuid::new_v4(); debug!( session_id = %test_session_id, postgres_url = %config.postgres_url.replace(&std::env::var("POSTGRES_PASSWORD").unwrap_or_default(), "[REDACTED]"), pool_max_size = config.pool_max_size, pool_timeout_secs = config.pool_timeout_secs, "Creating new database test pool" ); config.validate().map_err(|e| { error!( validation_error = %e, session_id = %test_session_id, "Database configuration validation failed" ); sqlx::Error::Configuration(e.into()) })?; let pool = timeout( Duration::from_secs(config.pool_timeout_secs), PgPool::connect(&config.postgres_url) ) .await .map_err(|_| { error!( timeout_secs = config.pool_timeout_secs, session_id = %test_session_id, "Database connection timed out" ); sqlx::Error::PoolTimedOut })?
