test_tools 0.19.1

//! Tests for local and published smoke testing (Task 035)
//!
//! These tests verify automated smoke testing against both local and published crate 
//! versions (US-3).
//!
//! ## TDD Approach
//! These tests are written FIRST and will initially FAIL if there are any gaps in
//! the dual smoke testing functionality, demonstrating the need for enhanced
//! implementation in Task 036.
