lambdust 0.1.1

//! Testing architecture with dependency injection and mocking support.
//!
//! This module provides a comprehensive testing framework for the monadic evaluator,
//! including dependency injection, mock implementations, and test utilities
//! that enable thorough unit and integration testing.

// Re-export all testing architecture components
