//! Test logging utilities for Reinhardt framework

//! Provides utilities for initializing logging in test environments.

/// This function ensures that logging is initialized only once across all tests.
/// It uses `env_logger` with test mode enabled.
///
/// # Examples
///
/// ```
/// use reinhardt_testkit::logging::init_test_logging;
///
/// // In your test:
/// init_test_logging();
/// // Your test code
/// ```
