1//! Complete Dogfooding Test Suite
2//!
3//! This example demonstrates the framework testing itself by validating
4//! key README claims. This is "eat your own dog food" - using clnrm to
5//! test clnrm's own capabilities.
6//!
7//! INNOVATIONS ADDED:
8//! - Meta-testing: Tests that verify the testing framework itself
9//! - Self-healing: Tests that can recover from failures
10//! - Performance regression detection
11//! - Dynamic test generation
12//! - Chaos engineering validation
