test_tools 0.18.1

//! Tests for conditional smoke test execution (Task 026)
//!
//! These tests verify that smoke tests execute conditionally based on `WITH_SMOKE` 
//! environment variable or CI/CD detection (FR-8).
//!
//! ## TDD Approach
//! These tests are written FIRST and will initially FAIL, demonstrating
//! the need for enhanced conditional execution implementation in Task 027.
