//! Test module for diagnostics CLI command (Session 6 spec)
//!
//! These tests define expected behavior BEFORE implementation.
//! Tests are designed to FAIL until the modules are implemented.
//!
//! # Test Categories
//!
//! ## 1. Tool invocation tests
//! - pyright, ruff, tsc, eslint output parsing
//! - cargo check, clippy output parsing
//! - go vet, golangci-lint output parsing
//!
//! ## 2. Unified format tests
//! - All tools produce Diagnostic structs with consistent format
//! - Line/column conversion (0-indexed to 1-indexed)
//!
//! ## 3. Severity filtering tests
//! - Filter by Error, Warning, Information, Hint
//!
//! ## 4. Auto-detection tests
//! - Detect which tools are installed
//! - Select appropriate tools per language
//!
//! ## 5. Parallel execution tests
//! - Tools run concurrently
//! - Timeout handling
//!
//! ## 6. Output format tests
//! - SARIF output (valid schema)
//! - GitHub Actions workflow commands
//! - JSON and text formats
//!
//! ## 7. Exit code tests
//! - Non-zero on errors
//! - Configurable --strict mode
//!
