mortar_cli 0.3.3

//! # main_tests.rs
//!
//! # main_tests.rs 文件
//!
//! ## Module Overview
//!
//! ## 模块概述
//!
//! Contains the unit tests that exercise the CLI entry helpers defined in `main.rs`. It
//! checks language conversion, command construction, flag parsing, and the basic file-oriented
//! workflow pieces that the binary relies on.
//!
//! 包含针对 `main.rs` 里 CLI 入口辅助函数的单元测试。它会检查语言转换、命令构建、
//! 标志解析，以及二进制程序依赖的基础文件工作流片段。
