//! Test logging utilities for rch tests.
//!
//! This module provides convenient wrappers around `rch_common::testing`
//! to standardize test logging across the crate.
//!
//! # Usage
//!
//! ```ignore
//! use crate::common::logging::{init_test_logging, TestLogger};
//!
//! #[test]
//! fn test_example() {
//!     init_test_logging();
//!     let logger = TestLogger::for_test("test_example");
//!
//!     // ... test logic ...
//!
//!     logger.pass();  // or logger.fail("reason")
//! }
//! ```
